7 VERSION New features 1 Display of PLC or CNC messages in Russian and Chinese By default, the texts defined by the OEM are in a single language and stored in several programs: PLCMSG Texts for PLC messages. PLCERR Texts for PLC errors. P Texts and titles used by all the OEM screens. P Help texts of the OEM screens or cycles. To have texts and messages in several languages, they must be grouped in a single program and set g.m.p. MSGFILE (P131) with that program number. The MSGFILE program may be in user memory, in the Memkey Card or in the KeyCF. If it is in more than one place, it takes the one in user memory. From this version on, PLC or CNC messages may be displayed in Russian and mainland Chinese. Windnc may be used to convert a file in standard Unicode format into a Unicode format customized for the Fagor CNC. The program number set in g.m.p. MSGFILE must be the same as the number of the program converted with Windnc. This way, once this program is sent to the CNC and after pressing [SHIFT/RESET], it will be possible to display these PLC or CNC messages in Russian and mainland Chinese. i Converting standard Unicode files into Fagor Unicode format requires Windnc version 5.1. This conversion is not possible with previous Windnc versions. On the other hand, since the CNC has CJK-Unicode characters, this system can also be used to display texts in traditional Chinese, Japanese and Korean. To do this, the CNC must be set in one of the following languages: English Chinese Russian MSGFILE program structure On each line, a text is defined preceded by ; the text number, a blank space and the $ sign. Examples: ;116 $Axis feedrate (F) ;117 $Tool (T) The texts must be grouped by subjects and languages. 1

8 The labels identify a group with a mnemonic in brackets and preceded by ;. ;[PLCMSG] Texts for PLC messages (up to 255). ;[PLCERR] Texts for PLC errors (up to 128). ;[CO999995] Texts and titles used by all the OEM screens (up to 256). ;[CO999994] Help texts of the OEM screens or cycles (up to 256). ;[OEMMSG] Other texts used in OEM programs (up to 768). The language number is indicated after the label and separated by a comma, the same number used by g.m.p. LANGUAGE (P122): (0) English ;[PLCMSG],0 (1) Spanish ;[PLCMSG],1 (2) French ;[PLCMSG],2 (3) Italian ;[PLCMSG],3 (4) German ;[PLCMSG],4 (5) Dutch ;[PLCMSG],5 (6) Portuguese ;[PLCMSG],6 (7) Czech ;[PLCMSG],7 (8) Polish ;[PLCMSG],8 (9) Chinese ;[PLCMSG],9 (10) Basque ;[PLCMSG],10 (11) Russian ;[PLCMSG],11 The text groups may be defined in the desired order, grouping them by subjects, languages, etc. i A Russian or Chinese message cannot be written in a program using the MSG command; it can only refer to a message number available in the described message files. e.g.: The message (MSG "change tool") cannot be written; instead, you would have to write the corresponding message number (MSG 1). Russian or Chinese comments cannot be displayed in a program even if that program has been converted using Windnc. 2

9 2 G233. Withdrawal of axes when interrupting a threading operation. New features When interrupting a thread (G33) either with a [STOP] or a feedhold, the axes withdraw from the part a safety distance that may be programmed with the new function G233. Once the tool has withdrawn, it returns to the cycle's starting point. Then, the machine remains stopped waiting for the [START] command to repeat the interrupted pass. The new function G233 is modal, it must be programmed alone in the block and it is displayed in the history. This function determines the thread exit for all the threads programmed after it. If there are several G33 functions in a row and each one of them has a different withdrawal, the corresponding function G233 must be programmed before each G33 function. Function G233 may be canceled by programming it alone in a block or by programming all the coordinates as zero. In this latter case, G233 disappears from history. If the [STOP] key is pressed while executing a thread and function G233 is active, the axes withdraw according to the distances programmed in that function. If in that very instant there is an active DSTOP, the blocks will still be executed until an ESTOP is found. If G233 is not active and [STOP] is pressed or there is a FEEDHOLD while executing G33, there is no withdrawal and the CNC stops at the end of the block. In the threading cycles where no thread exit has been programmed, the withdrawal distances will be the D and the J of that cycle. If a G233 function has been programmed before the cycle, the CNC will ignore it and it will consider the one programmed in the canned cycle, instead. Programming format: G233 X...C X...C +/-5.5 Thread exit distances. X: Incremental distance (positive or negative) to move along the thread exit axis (X axis). Z: Incremental distance to move along the thread axis (Z axis). X X Punto de salida de la rosca Punto de parada del ciclo Punto final Z STOP Punto inicial Z RETRACT mark: The RETRACT mark is activated when pressing [STOP] and the CNC begins the withdrawal. This mark will stay active until the withdrawal distances set in G233 are reached. 3

10 RETREJ variable: Read-only variable that indicates that the CNC has carried out a withdrawal from the thread. This variable takes the value of 1 when the withdrawal distances are reached and stays at 1 until pressing [START] or executing an M30 or a RESET. After executing one of these functions, it will take the value of 0. General machine parameter RETRACTE (P186): Operation depending on the value of bit 0 of g.m.p. RETRACTE (P186): Bit 0 Meaning 0 The threading withdrawal is not enabled in the threading cycles (G86 and G87). G233 may be programmed and simulated. 1 The threading withdrawal is enabled in the threading cycles (G86 and G87). In the cycles where no thread exit has been programmed, it withdraws to the safety coordinate moving the X axis. Default value 0 Example: Programming of a thread with G33 and G233 where a thread exit has been programmed so it stops at the starting point and repeats the threading that was aborted. N10 G90 G18 S500 M3 N20 G0 X20 N30 Z0 N40 (ESTOP) N50 X10 N60 G233 X5 Z-20 ; Block activating the thread withdrawal (5mm in X and -20mm in Z, same as the thread exit). N70 G33 Z-30 L5 ;Threading block that may be interrupted with STOP. N80 (DSTOP) N90 G33 X15 Z-50 L5 ;Block to exit previous thread. N100 (IF RETREJ EQ 0 GOTO N120) N105 G4 K0 ;Coordinate initialization after the exit. N110 (GOTO N20) N120 (ESTOP) If a STOP occurs in block N70, the CNC performs a thread withdrawal according to block N60. Then, it concludes block N70 and goes on with the execution in block N80 skipping block N90. Since there is a DSTOP, it continues the execution up to block N40 and stops. 4

11 3 Varying the override while threading It is possible to vary the override during a threading cycle. This feature affects canned cycles G86 and G87 while machining the thread in a threading cycle. A new spindle machine parameter THREAOVR (P85) has been added to set the maximum increment permitted for varying the override. Possible values: 0% - 30%. Default value = 0 (the override cannot be varied while threading). For example, a value of 30 means that the override may be varied between 70% and 130%. In spite of this, the limits set for the spindle with spindle machine parameters MINSOVR (P10) and MAXSOVR (P11), can never be exceeded. On the other hand, it will not be possible to vary the override in the last threading pass, it will be set to the value imposed in the previous threading pass. Spindle machine parameter M19TYPE (P43) must be set to "1" in order for the override to work while threading. In order not to damage the thread when varying the override, the feed-forward value must be close to 100% so as to work with a near-zero following error. 4 New low passing filters FIR. There are now new FIR (finite impulse response) filters. These filters are different from the previous IIR (infinite impulse response) filters. It is recommended to use this new low passing filter FIR instead of the previous IIR. Like before, these filters are set one per axis. To obtain a good machining quality, all the axes interpolating with each other should be defined with the same type of filter and with the same frequency. Machine parameters for defining the frequency filters: Each axis and spindle has the following machine parameters for configuring the filters: For the axes ORDER (P70) TYPE (P71) FREQUEN (P72) NORBWID (P73) SHARE (P74) For the spindle ORDER (P67) TYPE (P68) FREQUEN (P69) NORBWID (P70) SHARE (P71) Use the following axis and spindle machine parameters to set a new type of low passing filters FIR: ORDER (P70): Value Filter type [0-4] Low passing filter [0-4] Notch filter (anti-resonance) [0-30]* Low passing filter FIR * If you wish a low passing filter FIR, the maximum value permitted is 15. 5

12 Note: When detecting that the FIR filter order is too high for the filter configuration (according to parameters FREQUEN and LOOPTIME), on power-up it will issue the message: "It is recommended to lower the order of the frequency filter". It is recommended to start from low values (e.g.: ORDER=5) and go on increasing this value until that message is displayed. To use filters, it is recommended to use low values of PLC parameter PLC CPUTIME (e.g.: 0, 1), to assign to the CPU the strictly necessary amount of power. TYPE (P71): Value Filter type 0 Low passing filter 1 Notch filter (anti-resonance) 2 Low passing filter FIR Default value 2 FREQUEN (P72): The cuttoff frequency for the "low passing" filter is the frequency at which its amplitude drops 3 db or reaches 70% of the nominal amplitude. 5 Improvements in backlash compensation. Improved compensation peak cutting criteria The new axis machine parameter PEAKDISP (P98) defines the actual distance traveled along the corresponding axis after the theoretical reversal, from which the reversal peak is cut off on that axis. Its default value is This axis machine parameter will be taken into account when bit 1 of general machine parameter ACTBAKAN (P145) is set to 1 and it makes sense for the exponential peak (bit 0 of g.m.p. ACTBAKAN (P145) = 1) as well as for the square peak (bit 0 of g.m.p. ACTBAKAN (P145) = 0). If the value of axis machine parameter PEAKDISP (P98) = 0 and bit 1 of general machine parameter ACTBAKAN (P145) = 1, the compensation peak will be cut off with the second consecutive loop where the counting reversal has been detected. Example: cutting the exponential compensation off. [rev/min] BAKANOUT Orden de fin de ejecución de la compensación (corte). Se ha producido un movimiento del eje de PEAKDISP mm dado por la captación. [ms] Orden de ejecución de la compensación Posición teórica Feedback de posición de la captación Amplitud del movimiento parametrizado (PEAKDISP) 6

13 6 Improved home search on Gantry axes The following characteristics have been added: 6.1 Managing two home switches, one for the master axis and another one for the slave axis (only if the master has been set as I0TYPE (P52) =3): If both the master and the slave have a home switch (a.m.p. DECINPUT (P31) of the master and slave are YES): The CNC starts the movements of both axes in the direction indicated by a.m.p. REFDIREC (P33) of the main axis. This movement is carried out at the feedrate indicated by a.m.p. REFEED1 (P34) of the main axis. The axes move until one of them presses its home switch. Then, the home search will start on the axis that pressed the home switch first at the feedrate indicated by a.m.p. REFEED2 (P35) of the main axis. Once the first axis has been homed, its coordinate is initialized with a.m.p. REFVALUE (P36) and it starts homing the other axis. Master and slave start moving together at a.m.p. REFEED1 (P34) of the main axis until detecting the home switch of the second axis. It, then, starts homing the second axis at a.m.p. REFEED2 (p35) of the main axis and once detected, it initializes its coordinate. After this, depending on the value of axis machine parameter DIFFCOMP (P96), it will compensate for the difference between the master and slave axes or it will leave uncompensated. If the master axis is the first one to press the home switch and its a.m.p. REFSHIFT (P47) is other than zero, it does not start the second home search until executing the movement for the REFSHIFT (P47) on the master axis. Special cases: If when starting the home search, either the master or the slave is pressing the home switch, the axes will move until releasing the home switch and it then homes that axis first. If when starting the home search both the master and the slave are pressing the home switch, it first homes the master axis. When commanding a simultaneous homing of the gantry axis and other axes; it first moves all the axes having a home switch until all the home switches are pressed (in the case of a gantry pair, one of the home switches will be pressed). After this, if I0TYPE (P52) =3, the axes move one by one to release the home switches and search home in the selected order. 7

14 6.2 Managing the alignment between master and slave using a PLC mark and a machine parameter: After homing both axes of the Ganty pair, if a.m.p. of the master DIFFCOMP (P96) = 1, it corrects the position difference of the slave so the coordinate difference between the master and the slave is zero. The default value of axis machine parameter DIFFCOMP is 1. Whether parameter DIFFCOMP = 1 or = 0, the difference between the Gantry axes may be corrected at any time using the PLC mark SERVOaxisON and the new PLC mark DIFFCOMaxis (axis1: M5117, axis2: M5167, axis3: M5217, axis4: M5267, axis5: M5317, axis6: M5367, axis7: M5417), where "axis" is the name or the logic number of the master axis. The theoretical difference between the master and the slave is corrected as follows: With the leading edge (up flank) of DIFFCOMaxis while SERVOaxisON = 1. With the leading edge (up flank) of SERVOaxisON while DIFFCOMaxis = 1. Besides this, the machine parameter for the master axis MAXDIFF (P97) must be set. This a.m.p. indicates the maximum coordinate difference, in mm, between master and slave, from which on the position difference is not compensated. Its default value is 0 indicating that there is no maximum limit. Axis machine parameter MAXDIFF is taken into account when it is about correct the coordinate difference, in other words: if a.m.p. DIFFCOMP = 1, after the home search or by PLC mark. if a.m.p. DIFFCOMP = 0, only by PLC mark. If the position difference between master and slave is not compensated because the coordinate difference is greater than the value of a.m.p. MAXDIFF, PLC mark MAXDIFFaxis will be activated (axis1: M5605, axis2: M5655, axis3: M5705, axis4: M5755, axis5: M5805, axis6: M5855, axis7: M5905), where "axis" is the name or the logic number of the master axis. In this case the PLC can issue a warning. 7 Spindle homing with the first M3/M4 without M19 Until now, if spindle machine parameter M19TYPE (P43) = 1, executing a G33 Q on power-up required executing an M19. From this version on, if spindle machine parameters M19TYPE (P43) = 1 and DECINPUT (P31) = NO, the spindle will be homed on power-up or after pressing "SHIFT/RESET", when programming an M3 or an M4 for the first time. This search will be carried out at the feedrate set by a.m.p. REFEED2 (P35). After finding home, the spindle speeds up or down to the programmed speed without stopping. If the spindle has SINCOS feedback, the home search will be done directly at the programmed S speed without going through the speed set by a.m.p. REFEED2. If after power-up, an M19 is executed before an M3 or M4, that M19 will be executed like until now and the spindle will not be homed when executing the first M3 or M4. If the feedback device does not have the reference mark synchronized, the home search in M3 might not coincide with the home search in M4. This does not happen with FAGOR feedback. 8

15 8 Drive SET selection on "SWITCHED" axes. The parameters of the switch axes may be used to apply a gear ratio to each axis when having two Sercos axes that share the same drive. This allows controlling two completely different axes with the same motor. To do this, set the new axis machine parameter DRISET (P91). This parameter defines from which set of the drive will the following drive parameters be read: NP 121: Input rpm. NP 122: Output rpm. The possible values of a.m.p. DRISET (P91) are from 0 to 7, where 0 is the default value. A.m.p. DRISET (P91) is only taken into account when two Sercos axes share the same drive with switch parameters. Otherwise, it will read the data of set 0. Special cases: When the C axis of a lathe shares a drive with the spindle, if parameter DRISET (P91) = 0, it reads the values of the drive's set 7. This is because set 0 is reserved to the spindle. 9 Look-Ahead. Angle from which on, it machines in square corner mode The B parameter has been added to the Look-Ahead (G51) function. Programming format: G51 A E B B Angular value of the programmed corners, below which, the machining operation will be interrupted to machine it in square corner mode. This is valid for both outside and inside machining. The possible B values are between 0º and 180º. BLOQUE i B BLOQUE i 1 If B is not programmed, the square corner management at the corners is canceled. The square-corner management at the corners is valid for the look-ahead algorithm with jerk management and for the look-ahead algorithm without jerk management. 10 MDI movements in TEACH_IN mode From this version on, it is possible to make movements in MDI while editing a program in "EDITING/TEACH_IN" mode. Once a block has been edited and before pressing [ENTER], it is possible to press [START] to execute that block. After that, it is possible to enter the block into the program pressing [ENTER] or not by pressing [ESC]. While executing an MDI block in TEACH_IN mode, bit 2 of the OPMODA variable will be set to 1. 9

16 11 Improvements to the oscilloscope and direct access from jog and execution modes. The improvements to the oscilloscope are the following: Access to PLC resources The following programming format is used to access them from the configuration screen: Marks: PLC.M1234 Inputs: PLC.I25 Outputs: PLC.O1 Registers: PLC.R560 Register Bit: PLC.B0R560 Timers: PLC.T1 Counters: PLC.C1 Access is also possible using the associated symbol. An error will be issued when accessing a non-existent PLC resource. Continuous on-screen capture (ROLL ON) When pressing the <BEGIN> softkey, the CNC begins displaying the captured data on the screen. Continuous capture mode. In continuous capture mode, when the trace fills up the screen, the capture goes on except if the trigger has triggered; in that case the trace of the trigger remains until a new trigger is activated. Direct access from jog and execution modes: It is possible to access the oscilloscope from the main screens of the jog and execution modes by pressing [7] and then [1]. 10

17 12 Editing on Hard Disk Until now, the programs could be saved in several devices such as user RAM, Memkeycard, hard disk, remote disk and USB disk and a program could only be edited if it was in user RAM. From this version on, it is also possible to edit the program stored in the hard disk and in the remote disk as long as these devices are available. When carrying out any operation, the disk must have as much free memory or more than the size of the program where that operation is being carried out. The program to be edited may be selected in two ways depending on whether the explorer is used or not: A. Without using the explorer, with g.m.p. EXPLORER (P180) =0: Pressing the <EDIT> softkey makes it possible to select programs contained in the "/prg" folder of the user RAM, hard disk or remote disk. B. From the explorer, with g.m.p. EXPLORER (P180) =1: Pressing the <EDIT> softkey makes it possible to select programs contained in any subfolder of the user RAM, hard disk or remote disk. The operations that may be carried out with the files of the hard disk and remote disk are the same as those that could be carried out before this version with a file of the user RAM. The only difference is in the operation to "include program". The "include program" operation lets the user include the full content of a program in the one being edited. To do this, pressing <INCLUDE PROGRAM> will launch an explorer window for selecting the program to be included. This way, it is possible to select any program from any device and any subfolder except DNC. In the "Copy to program" operation, if the target program already exists and cannot be modified, the operation will not be carried out and the CNC will issue an error message. The "include program" operation can be used with a program that cannot be modified. Hidden programs cannot be edited even if they appear on the directory when pressing <SEE ALL>. The "Include program" operation cannot be carried out with this type of programs. The "copy to program" operation cannot be carried out either, if the program already exists and is hidden. 11

18 13 Data backup copy. Backup - Restore This option may be used to make a backup copy of the CNC configuration data to be restored later on if necessary. The general backup and restore may be carried out on any device (Memkeycard, hard disk, DNC and USB). Configuring the backup options Accessing <STATUS> / <CNC> / <BACKUP/RESTORE>, it is possible to select either the "Backup" or "Restore" option. After selecting one of these two options, an explorer window appears for selecting the source/target of the Backup/Restore operation. The selected configuration is saved for the next time "Backup/Restore" is used. This screen shows a table for selecting everything that is to be saved or restored. OEM programs: PLC program, MSGFILE program, CFGFILE program, STPFILE, USR* program, PLC messages and PLC errors. If any of the programs described is not an OEM program, it will request confirmation to make it OEM. If you chose not to make it OEM, it will not be saved. CNC tables and parameters: Tables for zero offsets, tool offsets, tools, arithmetic parameters and geometry. General machine parameters, for axes, spindles, serial lines, ethernet and hard disk, PLC, M functions, for leadscrew error compensation and cross compensation. Screens: ".PAN" files: Customized screens (pages) generated with VGDRAW and DRAW55. Servo drive parameters: Parameters for all the drives. This field is only shown when using a Sercos or CAN servo drive system. These parameters are saved to and restored from the drives. User programs: Visible and hidden user programs. The same screen shows the softkeys to start the Backup and the Restore: <BEGIN BACKUP> and <BEGIN RESTORE>. It also shows other softkeys such as OEM data, options or modify. If an error occurs, the CNC will request confirmation to resume copying. Backup and Restore are not possible in a hard disk module. Backup and Restore via WINDNC (including screens) requires WINDNC version V5.1 or greater. Otherwise, the CNC will display the corresponding error. 12

19 Backup Backup is carried out using the <BEGIN BACKUP> softkey. Pressing this softkey makes a safety copy (backup) of the data contained in the indicated folder. The data is saved in the selected file. When doing a Backup, each file goes to its corresponding folder (PRG, TAB or PAN). If these folders are missing, they will be created. Backup is not possible in a subfolder PRG, TAB or PAN, only the folder containing these subfolders may be selected. Restore The backup data is restored using the <BEGIN RESTORE> softkey. When doing a Restore, the data is restored in the following devices: Screens: in Memkeycard or KeyCF Servo drive parameters: at the drives In the rest of the CNC files: in RAM memory If servo drive tables or parameters have been selected, the emergency must be activated while doing a Restore. Otherwise, corresponding error will be issued. 13

20 When Restore is done, the CNC is restarted. If the drives are not on, the CNC will issue the relevant warning. If during Restore, there are errors in the table data, the message window will display them in green. The Restore operations will be registered in the CNC status register. OEM data The <OEM DATA> softkey may be used to select/deselect all the OEM data. OEM programs CNC tables and parameters Screens Servo drive parameters After selecting the desired OEM data, it is possible to back them up or restore them using the <BACKUP> or <RESTORE> softkeys. 14 New set of gains and accelerations There is now a third set of gains and accelerations for the axes and the spindle. General machine parameters ACTGAIN2 (P108) General machine parameter ACTGAIN2 indicates when the CNC assumes the second set of gains and accelerations indicated by a.m.p.. ACCTIME2 (P59), PROGAIN2 (P60), DERGAIN2 (P61) and FFGAIN2 (P62) and s.m.p. ACCTIME2 (P47), PROGAIN2 (P48), DERGAIN2 (P49) and FFGAIN2 (P50). This parameter has 16 bits counted from right to left. Each bit has a function or work mode associated with it. By default, all the bits will be assigned the value of 0. Assigning the value of 1 activates the corresponding function. Value Meaning Value Meaning 0 Threading in blind threads 8 G51 (for lathe only) 1 G34 9 G G G48 4 JOG 12 G47 5 Rigid tapping 13 G33 6 G95 14 G01 7 G75/G76 15 G00 Default value in all the bits: 0 14

21 ACTGAINT (P185) General machine parameter ACTGAINT indicates when the third set of gains and accelerations indicated by a.m.p. ACCTIMET (P92), PROGAINT (P93), DERGAINT (P94) y FFGAINT (P95), and s.m.p. ACCTIMET (P81), PROGAINT (P82), DERGAINT (P83) and FFGAINT (P84). This parameter has 16 bits counted from right to left. Each bit has a function or work mode associated with it. By default, all the bits will be assigned the value of 0. Assigning the value of 1 activates the corresponding function. Value Meaning Value Meaning 0 Threading in blind threads 8 G51 (for lathe only) 1 G34 9 G G G48 4 JOG 12 G47 5 Rigid tapping 13 G33 6 G95 14 G01 7 G75/G76 15 G00 Default value in all the bits: 0 New features Axis machine parameters ACCTIMET (P92) PROGAINT (P93) DERGAINT (P94) FFGAINT (P95) These parameters define the third set of gains and accelerations. They must be set like the parameters that define the first set. First set Second set Third set ACCTIME (P18) ACCTIME2 (P59) ACCTIMET (P92) PROGAIN (P23) PROGAIN2 (P60) PROGAINT (P93) DERGAIN (P24) DERGAIN2 (P61) DERGAINT (P94) FFGAIN (P25) FFGAIN2 (P62) FFGAINT (P95) To select the third set of gains and accelerations, set g.m.p. ACTGAINT (P185) correctly or activate the CNC s general logic input ACTGAINT (M5063). Spindle machine parameters ACCTIMET (P81) PROGAINT (P82) DERGAINT (P83) FFGAINT (P84) These parameters define the third set of gains and accelerations. They must be set like the parameters that define the first set.

ACTGAINT (P185) correctly or activate the CNC s general logic input ACTGAINT (M5063). 15

22 Operation: Every time each of these functions or work modes is activated, the CNC checks the value assigned to the corresponding bit and acts as follows: If any of the bits of ACTGAIN2 is set to 1, it applies the second of the sets ACCTIME2, PROGAIN2, etc. If any of the bits of ACTGAINT is set to 1 and all the bits of ACTGAIN2 are set to 0, it applies the third set ACCTIMET, PROGAINT, etc. When those functions or work modes are deactivated, the CNC applies the first set ACCTIME, PROGAIN, etc.. The gains and accelerations may also be changed from the PLC. To do that, there are general logic CNC inputs ACTGAIN2 (M5013) and ACTGAINT (M5063). ACTGAIN2: Every time this input is activated, the CNC selects the second set of gains and accelerations regardless of the active operating mode or function. ACTGAIN: Every time this input is activated, if the ACTGAIN2 mark is not activated, the CNC selects the third set of gains and accelerations regardless of the active operating mode or function. 15 Threading in blind threads A blind thread is a thread where σ (length of the thread exit) is not programmed. Threading with programmed thread exit. (σ > 0) Threading without programmed thread exit. (σ = 0) The third set of gains and accelerations for the axes and the spindle may be used to improve the adjustment and the machining of the exit from blind threads. The special handling of machining blind threads is set by bit 0 of the parameters used to define the current set ACTGAIN2 (P108) and the new general machine parameter ACTGAINT (P185). This bit defines the set of gains and accelerations only for blind threads made with turning canned cycles both in ISO code and conversational language and does not affect other types of threads with programmed exits. If the thread exit is a short distance, any acceleration set may be used or even remove the acceleration without getting the error "insufficient acceleration while threading". 16

23 16 MSGFILE: Number of PLC messages and errors limited to 255 and 128 respectively New features Up to 255 messages and 128 errors may be edited in the file indicated by general machine parameter MSGFILE (P131) used to edit PLC messages and errors in various languages. There are now more PLC marks to process them: MSG1 - M MSG255 - M4254 ERR1 - M ERR128 - M Improvements to the profile editor 18 Jogging in G95 The following improvements have been implemented in the profile editor: The coordinate axes are displayed with the name of each axis in their positive direction. It also resizes those axes. On any menu where no data is being edited or elements being selected, it will be possible to change the zoom using the [+]/[-] keys and to move the graphics using the arrow keys. The profile graphics takes into account the value of general machine parameter GRAPHICS (P16) to determine the direction and position of the axes. This improvement is valid for the mill and lathe models and is especially interesting for vertical lathes. In a profile created with this version: The direction of the axes are taken from g.m.p.graphics (P16). If while editing a profile, the user changes the configuration of the direction of any of the axes and presses "VALIDATE", the new configuration will be registered when saving the profile. Once this is done, when restoring the profile, the saved configuration will also be restored. If while editing a profile, the axis direction configuration is not changed, no reference to them will be saved and when restoring that profile, the direction of the axes will be taken from g.m.p. GRAPHICS (P16). In a profile of a version older than this one: When restoring a profile of a version older than V13.01 or V14.01, the direction of the axes will be taken from g.m.p. GRAPHICS (P16). When g.m.p. IFEED (P14) =1 and g.m.p. FPRMAN (P75) =YES, the jog movements are carried out in mm/rev; therefore, the spindle must have an S programmed. From now on, if the axis to be jogged does not belong to the active plane, the movement will be carried out in mm/minute; thus, it will not be necessary to program an S at the spindle. Also, if any axis of the plane is the Y axis, it won't be necessary either to program the S for jog movements in any axis, regardless of whether it belongs to the plane or not. This feature is especially interesting for auxiliary axes, center rests and tailstocks, because, in those cases, the S has no effect. 17

24 19 Faster rigid tapping and without sending M functions to the PLC This version improves the rigid tapping speed. One of the improvements consists in that the M3, M4 and M5 are not sent to the PLC. If bit 0 of g.m.p. TAPTYPE (P188) = 1, the M3, M4 and M5 that are executed in rigid tapping will still appear in the history, but they will not be sent to the PLC. Since these M's are not sent to the PLC, the dwells associated with them are eliminated and, consequently, the cycle will be faster. General machine parameter TAPTYPE (P188): Operation depending on the value of bit 0 of g.m.p. TAPTYPE (P188): Bit 0 Meaning 0 Regular rigid tapping. 1 Rigid tapping and without sending M functions to the PLC. Default value 1 20 TC model: Improved oscilloscope The improvements to the oscilloscope are the following: Access to PLC resources The following programming format is used to access them from the configuration screen: Marks: PLC.M1234 Inputs: PLC.I25 Outputs: PLC.O1 Registers: PLC.R560 Register Bit: PLC.B0R560 Timers: PLC.T1 Counters: PLC.C1 Access is also possible using the associated symbol. An error will be issued when accessing a non-existent PLC resource. Continuous on-screen capture (ROLL ON) When pressing the <BEGIN> softkey, the CNC begins displaying the captured data on the screen. Continuous capture mode. In continuous capture mode, when the trace fills up the screen, the capture goes on except if the trigger has triggered; in that case the trace of the trigger remains until a new trigger is activated. Direct access to the oscilloscope The oscilloscope may be accessed from the standard and auxiliary screens by pressing [7] and then [1] as long as no data is being written into any field. 18

25 21 TC model: It is possible to select only the roughing or the finishing New features A box has been added to the right of the text "ROUGHING" to select whether to do the roughing or not When de-selecting the roughing, all its data will stay in gray. When selecting the roughing again, all the data will be shown again. A box has also been added to select whether to do the finishing or not. Some of the data of the finishing side are activated/canceled with the box for roughing. This data is the following: Side residual stock in lathes Use bit 7 of general machine parameter CODISET (P147) to activate this option: Value Meaning 0 Neither roughing nor finishing can be selected. 1 Either roughing or finishing can be selected. Default value 1 22 TC model: Varying the override while threading It is possible to vary the override during a threading cycle. This feature affects canned cycles G86 and G87 while machining the thread in a threading cycle. A new spindle machine parameter THREAOVR (P85) has been added to set the maximum increment permitted for varying the override. Possible values: 0% - 30%. Default value = 0 (the override cannot be varied while threading). For example, a value of 30 means that the override may be varied between 70% and 130%. In spite of this, the limits set for the spindle with spindle machine parameters MINSOVR (P10) and MAXSOVR (P11), can never be exceeded. On the other hand, it will not be possible to vary the override in the last threading pass, it will be set to the value imposed in the previous threading pass. Spindle machine parameter M19TYPE (P43) must be set to "1" in order for the override to work while threading. In order not to damage the thread when varying the override, the feed-forward value must be close to 100% so as to work with a near-zero following error. 19

26 23 TC model: Jogging in G95 When g.m.p. IFEED (P14) =1, the jog movements are carried out in mm/rev; therefore, the spindle must have an S programmed. From now on, if the axis to be jogged does not belong to the active plane, the movement will be carried out in mm/minute; thus, it will not be necessary to program an S at the spindle. Also, if any axis of the plane is the Y axis, it won't be necessary either to program the S for jog movements in any axis, regardless of whether it belongs to the plane or not. This feature is especially interesting for auxiliary axes, center rests and tailstocks, because, in those cases, the S has no effect. 24 TC model: Possibility of programming certain M functions in TC. From this version on, there are auxiliary M functions in the cycles of the TC work mode. These auxiliary M functions may be selected in all the cycles both for roughing and for finishing. Enabling the auxiliary M functions in the roughing and finishing operations of the cycles displays a window where up to 4 auxiliary M functions. These functions are executed at the beginning of the operation (roughing or finishing) where they have been defined. Use bit 0 of general machine parameter CODISET (P147) to activate this option: Value Meaning 0 There are no auxiliary M functions. 1 There are auxiliary M functions. Default value 0 25 TC model: Profiling cycle 1 and 2 with 45-degree withdrawal. The Ds data has been added to profiling cycles 1 and 2 with machining passes parallel to the X and Z axes. This data helps set the safety distance the tool withdraws after each pass. This withdrawal is done at 45º (left figure). Icon to validate the Ds data. If the data is not validated, there is no withdrawal. If the data is validated, the display graphic changes and there is a withdrawal. 20

27 26 TC model: Approach distance "C" in the drilling cycle Parameter C (approach distance in each penetration - peck -) has been added to the following cycles: Drilling cycle (level 1). Multiple drilling cycle (level 3). This parameter defines the rapid approach distance for the axis from the previous drilling step to start the next drilling step. When moving the X axis, parameter C is programmed in radius. If parameter C is not programmed, a value of 1mm is assumed. 27 TC model: Customizing the TC for vertical lathes From this version on, when general machine parameter GRAPHICS (P16) = 2 (X axis positive to the right) or = 3 (X axis positive to the left), the screen will display the new graphics for vertical lathes. The profile editor, in profile graphics, takes into account the value of general machine parameter GRAPHICS (P16) to determine the direction and position of the axes. This improvement is valid for the mill and lathe models and is especially interesting for vertical lathes. 21
