6 PBO1 / Profibus DP Function The field bus system Profibus DP is coupled with the MX frequency converter by installing the option card PBO1 in the X3 slot see MX Projecting Manual. The data exchange between the "DP Master" and the "DP Slave (MX)" is designed in accordance with the specifications for the Profibus DP as defined in the standard DIN EN 50170/2. (DINE Part 3). Structure of the Profibus DP User Data The structure of the user data is in accordance with the profile for variable speed motors and is described in the VDE Directive 3689 Sheet 1. Diagram of Data Exchange in accordance with Profidrive Profile Option Profibus /01 - page 4

7 In accordance with the PPO type (Parameter - Process Data - Object see diagram) defined in the Profibus profile for variable speed motors, the process data area (PZD) for the control word consists of the following user data: Main control word with a 16-bit command chain, whereby the meaning of 11 bits is standardized, and at least one Main reference value (16-bit display, %, resolution 2-14 ) The status word, on the other hand, consists of the following user data: Status word 16-bit (bits 0-10 standardized) and at least one Main actual value (16-bit display, %, resolution 2-14 ) If, in addition to the process data exchange (real-time mode), parameter values are also to be read or adjusted, an additional 4 words are required see PKW - Parameter Code Value. All data (PKW and PZD) are 16-bit information chains that must be regarded as "words". Transmission is carried out in two 8-bit bytes, whereby the high byte (8-15) is transmitted before the low byte (0-7). The PPO type used is defined during configuration of the DP Master, and is set in the MX using parameter B6.34. Parameter - Process Data - Object (PPO): The Parameter - Process Data - Object (PPO) is defined for cyclical data exchange between the DP Master and Slave. Both process data and parameters can be transmitted with this object. It describes the available user data structures in numbers, and the meaning of the individual words. PPO type 3 and 4 are purely process data objects, type 1 and 2 also allow cyclical parameter processing. Option Profibus /01 - page 5

8 Network Configuration: The Profibus DP bus access process is based on the master-slave principle, whereby the slave can be read by an master, but can only be written to by one master. A maximum of 126 subscribers can be operated on the bus, but only in individual segments. The maximum number of subscribers per segment is 32 including the repeater. Electric Network: Rt... Terminating resistor Technical data for an electric network Maximum number of subscribers: Maximum number of subscribers per segment: Maximum repeater cascades: Bus cable: Terminal resistance: 126 in all segments 32 including the repeater 7 at 500 Kbaud bus speed 4 at 1.5 Mbaud bus speed A screened, twisted two-wire cable must be used as bus cable (wire type A, e.g. Siemens 6XV AH-10). Characteristic impedance: Ω, rated value: 150 Ω Distributed capacitance:: < 30 nf / km Loop resistance: < 110 Ω / km Wire cross-section: > 0,34 mm 2 Each bus segment must be provided with a resistance combination at both ends. The terminal resistances are in the bus plug of the two outer bus subscribers, which also supply them with electricity. Option Profibus /01 - page 6

9 Plug connector: The bus is connected using a 9-pin sub-d plug connector. Male terminal strip on the bus cable, female terminal strip on the bus subscriber. The bus plugs are designed as T junctions, whereby the bus line sections in the plug connector are fixed. The terminal resistances are in the bus plug and can be switched on and off using DIP switches. e.g. Siemens 6GK EA-00 Baud rate, line lengths: Depending on the baud rate and when using the described bus cable (type A), the following line lengths per segment are permissible: Baud rate [kbit/s] 9,6 19,2 93,75 187, (3000) (6000) (12000) Length [m] (100) (100) (100) Experience has shown that with a line cross-section of 0.5 mm 2, double the line lengths are also possible. Option Profibus /01 - page 7

10 Optic (mixed) Network: The optic network can be set up with the help of OLM's (Optical Link Modules) or active star connectors in a line, ring or star structure. Optical Link Module (OLM s) - optical coupling module for connecting electric segments with repeater function - transmission rate 9.6 Kbaud to 1.5 Mbaud Optical bus terminal - for connecting individual subscribers with OLM's or star connectors - supply from the bus subscriber Active star connetor - for setting up star structures - max. 16 slots (subscribers) - slots for plastic and optical waveguides For technical details on the optical bus components, please refer to the relevant manufacturer documentation. Option Profibus /01 - page 8

11 Cycle Times: For bus cycle times depending on the number of DP bus subscribers, see the following diagrams for each PPO type. The following calculation principles apply to the calculation of bus cycle times: tsdi = 37 bit; tsdr = 11 bit; for worst case 50% telegram repeats! (pessimistic assumption) Option Profibus /01 - page 9

12 Configuration of the DP-Master: The Profibus DP device master file (.GSD) for the MX series frequency converter must be used for configuration of the DP Master system. This standardized configuration file (VEE_1234.GSD) contains all the subscriber-specific information (in accordance with Profibus Standard Part 3) for coupling with the master. In the event of problems with the master configuration, please contact the supplier of the DP Master system. For Profibus DP Masters from the Siemens S5 & S7 product families, the relevant type files for integration using the Siemens configuration program COM ET 200 are available in addition to the GSD files. COM ET 200 (DOS) COM ET 200 (WINDOWS) COM PROFIBUS VE1234TD.200 VE1234AX.200 VEE_1234.GSD These files are available on floppy disk (3 1/2"), order number Option Profibus /01 - page 10

13 Installation of the option card PBO1: The front cover of the MX frequency converter must be removed for installation of the option card Profibus PBO1 in the converter. The option card is placed on the left slot of the user interface (UI) marked X3, and must be fixed with the enclosed screws (M3x5) after correct insertion of the connector strip. The device must not be live during installation!! Control panel User-Interface UI Option IO1 at slot X2 Option PBO1 at slot X3 In order to be able to address a converter via the Profibus even when not on line (mains switch control, power switch,...), the user interface on the MX must be supplied with an external 24 V buffer voltage (at MX 700 a 1 AC 230 V auxiliary voltage must be applied).

15 2 Parameter Area PKW Parameter Area PKW - General First Word PKE 14 Second Word IND 14 Third & Fourth Word PWE-High, PWE-Low 15 Rules for Job and Response Processing 15 Detailed Description of Words in the PKW Area Parameter Code PKE Parameter Index IND Parameter Value PWE Examples PSR3/PSR4 - Trip causes 28 ASCII Table 29 Option Profibus /01 - page 13

16 Parameter Area PKW: The parameter area consists of 4 words and is used for reading and writing parameter values, and for reading parameter description elements. In the PKW mechanism, the master formulates a job, the converter processes the job and sends back a corresponding response. Internally, a job is processed by the converter every 100 ms, i.e. a job is accepted and a response prepared for collection. The converter keeps the response ready until the master formulates a new job. The job and response have the following data format: First Word PKE The parameter code is used for parameter selection (PNU code) and for assignment of a specific "job" in the job telegram, e.g. write (edit) parameter value, read (request) parameter value, etc. In the response telegram, a corresponding response code is transmitted analog to the job code. Second Word IND If the job code is "Request description element", the required description element for the parameter selected with the PNU code must be indicated by specifying a subindex. Option Profibus /01 - page 14

17 Third & Fourth Word PWE - High, PWE - Low In the two words for the parameter value, the value of the parameter selected with the PNU code is transmitted (job or response protocol). If the job code is "Request description element", the information corresponding to the subindex is contained in the parameter value. Rules for job / response processing The master must continue issuing a job until it has received the corresponding response from the converter. While processing the job, the converter transmits the response for the previous job. The master must identify the response to a job: a) by evaluation of the response code b) by evaluation of the parameter number c) possibly by evaluation of the parameter index d) possibly by evaluation of the parameter value Jobs and responses must be transmitted completely in one telegram, blocked jobs are not possible. If the responses contain actual values (response code 1 and 4), the converter always responds with the actual value when repeating the response telegrams. If information is not to be exchanged via the PKW mechanism, the master must use the job code "no job". For write jobs, the transmitted value in the response must also be evaluated (job canceled if the value remains the same or an error occurs.) Following responses containing an error code (response code 7), "no job" (job code 0) must be entered in the job list, if the next regular job refers to the same PNU number (delete last trip message). Option Profibus /01 - page 15

18 Detailed Description of Words in the PKW Area Parameter Code (PKE) This 16-bit value defines the type of parameter jobs and responses. Parameter number PNU Spontaneous reports SPM Job Code AK Bits 0 to 10 contain the parameter number (PNU), with the help of which individual parameters can be accessed. For the PNU codes of the individual matrix parameters, see parameter list in the appendix. Bit 11 is used as a toggle bit for spontaneous reports for the transmission of active parameters. This bit is not set in the MX. Bits 12 to 15 contain the job and response code. This is defined so that it indicates which fields of the PKW interface (IND, PWE) have to be evaluated, as well as their contents. Only specific response codes can be assigned to each job code. If a job cannot be processed (response code 7), the field PWE-L (4th word) contains the relevant trip number. Job Codes (Master Converter): Job Meaning Response Code Code pos. neg. 0 no job request parameter value 1,2 7 2 edit parameter value (word) edit parameter value (double word, NF) request description element *) **) request parameter value (array) **) 4,5 7 9 request number of array elements 6 7 *) On the Profibus DP interface, only description elements with a maximum length of 4 bytes can be transmitted in the PKW share. Therefore, the elements NAME and TEXT cannot be read by the DP Master. **) The subindex for the required parameter description element or the indexed parameter is indicated in the field IND (2nd word of PKW area). Option Profibus /01 - page 16

19 Response Codes (Converter Master): Response Meaning Code 0 no response 1 transmit parameter value (word) 2 transmit parameter value (double word, NF) 3 transmit description element 4 transmit parameter value (array, word) 5 transmit parameter value (array, double word) 6 transmit number of array elements 7 unable to perform job (with trip number) Error Codes for Responce: Error Meaning Code 0 inadmissible parameter number 1 parameter value cannot be edited 2 lower and upper value limit exceeded 3 faulty subindex 4 no array 5 incorrect data type 9 description data not available 11 no parametrization priority for parameter 13 text (or text array) cannot be read in cyclical DP operation 14 name cannot be read in cyclical DP operation 17 unable to perform job because of operating status (pulse enable) 101 incorrect job code (job not supported) 103 parameter access blocked by code 104 unable to set parameter value is already used 105 type of array 106 unable to perform job because of acitve 2. UserMakro or parameter lock (digital input) Parameter Index (IND): The index (or subindex) is an 8-bit value and is transmitted in the high byte. The low byte of IND always has the value 0. Value range: 1 to 255 For jobs and responses concerning the parameter description, IND contains the subindex for parameter description, which specifies the parameter. By indicating the subindex in the IND field of the PKW area, the individual description elements can be read. For jobs and responses concerning array elements, IND contains the array subindex.

21 Index 2 - Number of Array Elements This element is of the data type Unsigned 16, and is transmitted in the PWE-L. It contains the length of the value array or text array. Value range: 1 to 255 Index 3 - Standardization Factor This element is of the data type Floating Point (32-bit) and is the factor that transforms the (internal) parameter value into a descriptive size. Note: The standardization factor of the individual actual values can also be found in the parameter list in the appendix. Index 4 - Size Attribute This element is of the data type Octet String 2 and contains a code in the PWE-L (word 4) that defines the valid unit for the selected actual value parameter. Code Unit Code Unit 0000 hex dimensionless 0D43 hex m/min 0400 hex s 1000 hex Nm 0446 hex min 1164 hex C 044A hex h 1500 hex V 084C hex MWh 1600 hex A 0903 hex kw 1800 hex % 0A03 hex kva 1C00 hex Hz 0B43 hex rpm 6400 hex kgm 2 Presentation of parameters as physical values using the standardization factor and size attribute: The following conversion formulas apply, depending on the data type of the parameter value: a) Data type N2 (standardized value 16-bit) Physical value = Parameter value x Standardization factor 16384,0 Unit appropriates the size attribute Example 1: Display of output frequency Parameter value 09C4 hex (2500 dec) Standardization factor 163,84 Size attribute 1C00 hex (Unit Hz) Frequency = 2500 dec x 163,84 Hz= 25,0 Hz 16384,0 Option Profibus /01 - page 19

It is of the data type Octet String 4 and consists of "Password" (Octet 1), "Access Groups" (Octet 2) and "Access Rights" (Octets 3, 4). Only the field "Access Rights" is used for access to parameters. "Password" and "Access Groups" are not used and are always zero. Transmission in PWE: PWE-H 31 Zero Zero 16 PWE-L 15 Access-Rights 0 Code Access Right 8000 hex actual value F800 hex setting value not locked (V) B800 hex setting value depends on Para-Access (VB) 9800 hex setting value depends on Para-Access and code lock (VCB) 8800 hex setting value depends on Para-Access, code lock and pulse inhibit (VICB) Option Profibus /01 - page 20

23 Para-Access for Adjusting Parameters: The parametrization jobs for the 3 user interfaces (keypad, field bus, RS232) are processed in the 100 ms task. Within one task run, the individual parametrization jobs are processed one by one in the following order: 1. Jobs from the keypad 2. Jobs from the field bus 3. Jobs from the RS232 interface Reading parameter jobs (reading of parameter values, description elements) are always accepted from all 3 user interfaces. The processing of write parameter jobs (editing parameter values) depends on the parameter F6.02 Para- Access (PNU 927). PNU 927 (F6.02) = 0 Editing only possible via keypad PNU 927 (F6.02) = 1 Editing only possible via field bus PNU 927 (F6.02) = 2 Editing only via RS 232 Depending on the parameter type, the other access rights (code lock and pulse inhibit) must also be observed when actually changing values. The Para-Access (F6.02 / PNU 927) itself can always be changed from any user interface, however (i.e. each interface can "get" the Para-Access for itself). The terminal strip input "PARA lock" is only effective for the keypad, but it locks all the parameters (including Para-Access). Index 7 - Lower Limit This element has the same data type as the parameter value and defines its lower limit. Index 8 - Upper Limit This element has the same data type as the parameter value and defines its upper limit. Option Profibus /01 - page 21

24 Parameter Value (PWE) The field PWE is a 32-bit value and contains either the parameter value or the value of a description element. Depending on the job or response code, it defines in which PWE sector the information is expected or stored. A 16-bit value is transmitted in PWE-L (4th word), an 8-bit value in the low byte of PWE-L. The following data types are possible: for simple variables: N2 16-bit linear standardized value O2 unsigned 16 T2 time constant 16 bit NF floating point V2 bit sequence 16 bit for arrays: OS4[ ] octet string with length of 4 (array of ASCII character blocks) O2[ ] unsigned 16 Font: Characters (texts) must be represented using the character table ISO/IEC Latin Alphabet No. 1 (= Windows font). The parameter type and the available elements of parameter description are shown in the following table and in the parameter list in the Appendix. Option Profibus /01 - page 22

25 By requesting the parameter arrays (job code 6) for correct display on visual devices can be read: PNU 915 the PNU number of the control word and the selected reference values (PZD 1-6) PNU 916 the PNU number of the status word and the selected actual values (PZD 1-6).

For this purpose, the following PNU codes are available in addition to the standard matrix parameters. PNU- Code Parameter 790 f-ref Manual 791 f-ref Automatic 792 f-correction 793 M-limit 794 output frequency 795 Motor current 796 Motor voltage 797 speed 798 int. f-ref before accel. 799 int. M-limit For further details on the parameters, see parameter list in the appendix. Saving to Flash EPROM After changing parameters, all the parameters must be saved to the flash EPROM to protect the data in the event of a power cut. This is done with the parameter "PNU Save Backup". To start this process, the parameter value is set to 1. After saving, the parameter must be reset to 0. Option Profibus /01 - page 23

34 Process Data Area PZD During the cyclical exchange of process data, binary and analog reference and actual values are exchanged between the bus subscribers, i.e. between the DP Master and the DP Slaves. The achievable cycle time depends on the bus structure, the number of bus subscribers, and the transmission rates. See section Network Configuration. Internally, a control word is read and a status word prepared for collection by the master every 5 ms. The standardized information in the control and status word (bit 0 to bit 10) does not require any further internal settings. The reference value use, the actual value assignment and the use of the free bits (11-15) must be programmed accordingly in the matrix field "B6 Bus connection".

35 Description of control word bits: Bit Value Meaning Comment 0 1 ON Accepts the change from device state "1 Ready to switch on" to device state "3 Ready to run", if the intermediate circuit has already been loaded If the mains switch control is active: the device status changes to "2 Charge DC-L.", after successful loading it changes to "3 Ready to run" 0 OFF 1 After the command is accepted, the device status changes to "13 OFF1 active" and thus shuts down the drive at the rundown ramp. When the output frequency has reached zero Hz: the device status changes via "0 Not ready to switch on" to "1 Ready to switch on", if the basic status (bit 1 = 0, bit 2 = 1, bit 3 = 1 and bit 10 = 1) is present. If a renewed OFF 1 (On) command is issued during the rundown phase, the applied reference value is run to according to the acceleration ramp. Thereby, the device status changes to 7 Run With active mains switch control, the mains switch is disabled when changing to "1 Ready to switch on" 1 1 Operating condition "OFF 2" command canceled 0 OFF 2 After the command is accepted, the inverter is locked, (pulse inhibit) and the status changes to "19 Lock switching on". If the mains switch control is active, the main switch is disabled. The OFF 2 command can also be issued using the terminal strip function Pulse enable! When the basic status (bit 1 = 0, bit 2 = 1, bit 3 = 1 and bit 10 = 1) is applied, the device status changes to "1 Ready to switch on" 2 1 Operating condition "OFF 3" command canceled 0 OFF 3 After the command is accepted, the device status changes to "14 OFF3 active", resulting in fastest possible shutdown of the drive with maximum power or maximum intermediate circuit voltage. When the output frequency has reached zero Hz, the device status changes to "19 Lock switching on". If the mains switch control is active, the mains switch is disabled. If the OFF 3 command (bit 2 = 1) is canceled during deceleration, the quick stop is still carried out. Option Profibus /01 - page 33

36 Bit Value Meaning Comment 3 1 Operation released After the command is accepted, the inverter is released in the device status "3 Ready to run" (pulse inhibit) and the device status changes to "4 Operation released" 0 Lock operation When the command is accepted, the inverter is locked and the device status changes to "3 Ready to run". If the device status "13 OFF1active" applies, the inverter is locked and the device status "0 Not ready to switch on" is accepted. If the mains switch control is active, the main switch is disabled. If the basic status (bit 1 = 0, bit 2 = 1, bit 3 = 1 and bit 10 = 1) is applied, the device status changes to "1 Ready to switch on". If the device status "14 OFF3 active" applies, the action is still carried out! 4 1 Ramp output Device status "5 Ramp output released" enable 0 Ramp output After the command is accepted, the output of the runup transmitter disable is set to zero. The motor stops with maximum power or maximum intermediate circuit voltage. The device status changes to "4 Operation released". 5 1 Ramp integrator Device status "6 Ramp release" released run 0 Ramp integrator stop After the command is accepted, the reference value currently specified by the runup transmitter is frozen. The device status changes to 5 Ramp output released. 6 1 Release reference After the command is accepted, the selected reference value is value released at the runup transmitter input. The device status changes to "7 Run". 0 Lock reference value After the command is accepted, the input of the runup transmitter is set to zero. This results in a deceleration of the motor at the set ramp. The device status changes to "6 Ramp release". 7 1 Reset The Reset command is accepted with the positive flank in the device status "20 Trip". If the current error has been removed, the status changes to "19 Lock switching on". If the error persists, the device status remains "20 Trip". The Reset command can also be issued via the terminal strip function "EXT Reset" and via the red O button on the keypad. 0 no meaning Option Profibus /01 - page 34

37 Bit Value Meaning Comment 8 1 Jog 1 start The Jog 1 Start command is only accepted if the device status is "4 Operation released". Thereby, the motor warms up to the jog frequency set in parameter C1.13 as quickly as possible, the device status changes to "8 Jog 1_active". 0 Jog 1 off The command is only accepted, if Jog 1 Start was set to "1" before. Thereby, the motor slows down to zero Hz as quickly as possible, and then changes to the device status "9 Jog 1 Pause". If a renewed Jog 1 break command is issued within two seconds, it is executed immediately. At the end of the 2-second "Jog Timer", the device status returns to the initial status "4 Operation released". 9 1 Jog 2 start Command not supported by PSR2 and PSR 3 0 Jog 2 off Command not supported by PSR2 and PSR Control OK If the command is accepted, the DP Slave is tracking via the bus interface. Process data become valid. This bit must be set. Otherwise the control commands and/or the free bits and also the analog signals are not accepted! 0 No control If the command is accepted, all data depend on the status bit 9 Control requested == 1 reaction depends on trip of bus However, if the DP Slave continues to request tracking, the frequency converter switches to error status with the error message BUS_COMM2 (depends on the adjustment of parameter B6.03 at trip of bus ). A warning is always issued in this status! Control requested == 0 data are zero! only I/O operation or local operation Option Profibus /01 - page 35

39 Simplified Status Machine For standard control with defined commands: + Start / stop at the MX-internal runup / rundown ramps + Pulse inhibit + Emergency Stop + Confirm error The commands Pulse inhibit (OFF 2), Quick stop (OFF 3) and a confirmed error status always result in the device status "Lock switching on"! In order to return to the device status "Run", it is necessary to transmit the basic status (bit 0 = 0, bit 1,2 = 1) before transmitting the Start command (bit 0 = 1). After switching on the mains (booting the user interface), the basic status (bit 0 = 0, bit 1,2 = 1) must be applied in order to obtain the device status "Ready to switch on".

41 Main Reference Value (Auxiliary Reference Values) Depending on the PPO type used, one or five reference values are available in the Profibus user data protocol. The meaning of the individual reference value words (each 16 bits) is defined by parametrization via the matrix interface on the MX. The reference values can be divided into two groups: a) internal nominal values, e.g. reference f value, reference/actual PID value and the like (in accordance with the reference value use). b) for transmission to the analog outputs for external use, without influence on the converter control (bit 10 Control Word must be 1!). The reference values are presented as linear standardized values with 16-bit display (N2). I.e. 0% = 0 (0 hex), 100% = 214 (4000 hex) This results in the data area from -200% to +200% with a resolution of 2-14 (0,0061%). % Binary Hexadecimal Decimal 199, FFF , , , , FFFF , C , The reference values are standardized in Hz or % using the parameters B6.06 to B6.10. Use of the free bits 11 to 15: Bits 11 to 15 in the control word are not defined according to the Profibus profile, and can therefore be used freely by the user. By parametrizing the frequency converter accordingly, this digital information can be used a) for internal control signals (in accordance with the digital input use), or b) quite separate from the converter functions for information transmission via the digital outputs of the frequency converter (Bit 10 Control Word must be 1!). The additional information (bits 11-15) is added to the individual control word in the corresponding numerical format.

43 Description of status word bits: Bit Value Meaning Comment 0 1 Ready to switch on The device status is "1 Ready to switch on". The inverter is locked. If the mains switch is active, the main switch is disabled. 0 Not ready to switch on The device status is "0 Not ready to switch on" or "19 Lock switching on". 1 1 Ready to run The device status is "3 Ready to run". That means that the output component is live and there are no errors. However, the inverter remains locked. If the mains switch control is active, this operating message is issued during the loading phase. (device status "2 Charge DC-Link") 0 Not ready to run 2 1 Operation enabled The device states are "4 Operation released", "5 Ramp output released", "6 Ramp release", "7 Run", "13 OFF1 active" or "14 OFF3 active". The converter is operating with impulse release, the output terminals are live. 0 Operation disabled 3 1 Trip The motor has a fault and is therefore not operating. The device state is "20 Trip". After removal of the error and confirmation, the device status changes to "19 Lock switching on" 0 No trip 4 1 no OFF 2 0 OFF 2 An OFF 2 (pulse inhibit) command has been issued. (pulse inhibit) 5 1 no OFF 3 0 OFF 3 An OFF 3 (emergency stop) command has been issued. (Emergency Stop) 6 1 Lock switching on The motor is in device status "19 Switching on locked". This status is obtained with the commands OFF 2, OFF 3 and "Lock operation", and after successful confirmation of an trip. This operating status is cleared by setting bit 0 STW = 0. 0 Switching on enable Cancellation of the switching on lock with bit 1 in the control word. (OFF 1/ON) Option Profibus /01 - page 41

The window of tolerance and the rise and drop delay depends on D f, (n) f, (n) reference 9 1 Control requested If the frequency converter has been parametrized for bus mode using parameter B6.01 (control via serial port), it requests the DP Master to take over control when switched on at the mains or when an external 24 V buffer voltage is switched on. If the master does not take over control, a warning (ZSTW bit 7) is issued. 0 No bus mode If the converter is separated from the bus communication by switching to local mode (button on keypad), bit 9 is reset to zero. If the master does not send a Control OK (STW bit 10 = 0), a warning is issued. On renewed switch-over to remote mode = bus mode, the automation system must respond with Control OK within 2 seconds, otherwise the device is automatically switched back to local mode f f level The actual frequency value is than the reference value D f f level The actual frequency value is than the reference value D4.07.

45 Main Actual Value (Auxiliary Actual Values): Depending on the PPO type used, one or five actual values are available in the Profibus user data protocol. The meaning of the individual actual values is defined by parametrization via the matrix interface on the MX. The actual values can be divided into two groups: a) as internal actual values such as, e.g. actual speed, actual moment and the like (in accordance with the analog outputs of the frequency converter) b) as take-over from the analog inputs for external use by the DP Master (without influencing the converter control). Bit 10 STW must be 1! The actual values, like the reference values are presented as linear standardized values with 16-bit display. The standardization of the actual values is firmly assigned for each output value. See parameter B6.11. For further details on the presented data area, see chapter "Main Reference Value (Auxiliary Reference Values)". Use of the free bits 11 to 15: Bits 11 to 15 in the status word are not defined according to the Profibus profile, and can therefore be used freely by the user. With appropriate parametrization of the frequency converter, this digital information can be derived both from the internal operating states (in accordance with the digital outputs) and also totally separate from the converter functions via the digital inputs of the frequency converter. The additional information (bits 11-15) is added to the individual status word automatically.
