Connection to the inverter E Connect the vector-option unit to the inverter according to the procedures below. 2.1 Connection to the inverter (1) Confirm that the all power to the inverter are turned off beforehand. Note: Wait 10 minutes or more after turning the power off and confirm that the charge lamp on the inverter is unlit. (2) Fixing the vector-option unit alone by using screws <When the vector-option unit is installed alone> Tighten M4x25 screws with M4 nuts to an attachment of optional add-on cassette (separately procured) to fix the unit as shown in the figure below. <When the unit is installed with another option> Read instructions of connection with options on the following page for installation. Same procedures apply when three options are installed together. (When plural options are installed, order of installation from the inverter side is not specified.) (Note) Determine the initial setting of the bit switch for internal signal before connecting options. Mount a board for option connection, then use M4x50 screws and M4 nuts to fix the options as shown below. (When three units of option are installed, use M4x75 screws.) (3) Fixing the unit to the inverter Method for fixing the unit to the inverter differs according to the type of inverter to which the unit is installed. Refer to the instruction manual of Attachment of optional add-on cassette. 7

9 E Connection with options When two or more optional add-on cassettes are used, connect them with reference to the following diagram. Mounting of relay board for connecting options Following the diagram below mount the board which is attached to the vector option unit onto the unit for connecting options. Insert a flat head screwdriver into the triangular section at the right side of the option unit and remove the small window cover. Relay board mounting guide Triangular mark on the side face Slide the relay board into the place according to the insertion guide. (Note) Engage the patterned section of the board with the metal pad section of the connector and insert the board in parallel. When the insertion angle inclines, remove the board once and try again. Engage the patterned section of the board with the metal pad section of the connector and insert the board in parallel. When the metallic parts of the relay board is touched with bear fingers, they oxidizes and the contacting failure occurs. Put on gloves for the work. Connecting two options Connect options with reference to the diagram below. Triangular mark on the side face Fit two option s positioning guides on both units and connect two units not to shift the connecting position of the relay board. Hold a triangular section on the side of the unit and engage the relay boards securely. (Connection is satisfactory when the click sound can be heard.) If there is a gap between the units, two boards are misaligned. Carry out the work again from the beginning. Option s positioning guide (two guides on top and bottom) 8

10 E Wiring When conducting wiring, follow the instructions below. Use shield wire for control signal line and ground the unit with shield wire. (Use twisted pair shield cable for wiring of the analog monitor output.) Applicable wire size TB1, TB2: 0.2 to 1.5 mm 2 TB3: 0.2 to 2.5mm 2 Peel off the end of the wire about 5mm (7mm for TB3). For connecting wires, use screwdriver that has a blade tip of 0.4mm thickness and 2.5mm width. (For TB3, use screwdriver that has a blade tip of 0.6mm thickness and 3.5mm width.) Tightening torque of the terminal block is 0.22 to 0.25 N m. (For TB3, tightening torque is 0.5 to 0.6 N m.) Never bind the signal line and main circuit connection wire together. Use 0.75mm 2 wire for the connection of CC terminal (or PGCC terminal) of the expansion TB option and CC terminal of the inverter. Use 0.75mm 2 wire for the connection of grounding terminal of the expansion TB option and that of the inverter. < Input/output terminal interface > Terminal code B0~ B15 MON1 MON2 Function Electrical specification Internal circuit Contact point input Changeover of sink or source Analog output terminal Sink input ON: 5V or less (5mAtyp) OFF: 11V or over or 0.5mA or less Source input ON: 11V and 2.5mA or over (30Vmax) OFF: 5V or less or 1.4mA or less Current output: 0 20mA Allowable load resistance: 750Ω or less Converter circuit Voltage output: ±10VDC Output impedance: 4.7kΩ R1A, B, C R2A, B, C Relay contact point output Configuration of 1C contact point 250Vac-2A (cosφ=1) 250Vac-1A (cosφ=0.4) 30Vdc-1A P24 24V power supply 24VDC-100mA (total of optional add-on cassettes is 200mA or less) CC Common terminal of control circuit (Connect CC terminals of expansion TB option and inverter each other.)

12 E Since 0-20mA converter circuit is not insulated electrically inside the board of expansion TB option, place an insulator between the board and the expansion terminal block board when the unit is coupled with the circuit of 24V or over for control. When the signal is received remotely, it should be observed that the sum of the DC resistance and the load resisitance of the electric wire will not go over 750Ω Adjustment parameter for analog monitor Parameter Title Function Adjustment range f672 f673 f674 f675 f678 f679 f680 Optional analog terminal 1 meter selection Optional analog terminal 1 meter adjustment Optional analog terminal 2 meter selection Optional analog terminal 2 meter adjustment Optional analog terminal 1 meter offset Optional analog terminal 2 meter offset Selection of code for option analog meter (Valid when the frequency data is selected.) 0 to 31 Refer to output data selection table for details 0 to 31 Refer to output data selection table for details to 60% to 60% Setting: The first meter, The second meter 0: Standard Standard (absolute value) (absolute value) 1: With code Standard (absolute value) 2: Standard With code (absolute value), 3: With code With code Default setting Note 1: Optional analog terminal 1 and 2 meter offset titled by f678 and f679 are the parameters that is necessary to use only the output of forward side and to put out 4-20mA output.

15 E Adjustment method of analog monitor output (1) Current output (0-20mA output) Under the use of current output, method of output adjustment for analog monitor is the same as the case of "AM terminal meter selection" (f670). Refer to the instruction manual attached to the inverter. (2) Voltage output (±output) In the case of voltage output, meter adjustment under the condition of inverter halt cannot be set well unlike the case of current output and AM terminal meter selection, even when the fixed output for meter (30) is designated with the parameters "optional analog terminal meter selection" (f672 and f674). When the meter adjustment is difficult during the operation of inverter, try sending out the operation frequency command to the monitor, and the adjustment will be possible. Before attempting an adjustment, disconnect an output wiring of the inverter for the sake of safety, or ensure safe condition to avoid possible danger in the event when the inverter abruptly runs. When the analog monitor that is to be adjusted is being used for the manipulation of peripheral devices, terminate the operation of those devices and take necessary safety prevention. Adjustment example of monitor output 1 For this adjustment work, temporarily change the present parameter. Before changing the parameter, record the current set value. 1. Confirm that the inverter is in halt condition. 2. Select [1] (operation frequency command) in the parameter "optional analog terminal 1 meter selection" (f672). 3. Select [1] (coded only to No.1 meter) or [3] (coded both to No.1 and No.2) in the parameter "Selection of code for option analog meter" (f680). 4. Select [5] (operating panel input enabled) in the parameter "speed setting mode selection" (fmod). 5. Operate a panel and set 0Hz to the operation frequency command. 6. Adjust a zero point of the meter on the parameter "optional analog terminal 1 meter offset" (f678). 7. Operate a panel and set the operation frequency command to the maximum frequency (fh). When it is not possible to set operation frequency command to the maximum frequency (fh), first set the upper limit frequency (ul) to the same value of the maximum frequency (fh), then adjust the operation frequency command to the maximum frequency (fh). 8. Adjust the meter indication value in "optional analog terminal 1 meter adjustment" (f673). Types of adjustment level differ depending on the parameter "optional analog terminal 1 meter selection" (f672). See selection table listed on the previous page. (a) The maximum frequency (fh) will become the voltage value that is presently indicated. (b) 150% displayed on the panel will be the voltage value that is presently indicated. (c) 100% displayed on the panel will be the voltage value that is presently indicated. 9. Restore the operation frequency command on the panel to its original value. 10. Restore the speed setting mode selection (fmod) to its original value. 11. Restore the "Selection of code for option analog meter" (f680) to its original value. 12. Restore the optional analog terminal 1 meter selection (f672) to its original value. 13. If the upper limit frequency (ul) has been changed in the step of 7 above, restore it to the original value. 14

16 E Function of expansion input terminal Eight input terminals can be added. However when binary/bcd signal selection (f107) is used, terminals will function as the binary/bcd input terminals. Function is similar to that of the input terminals of the inverter, refer to the inverter instruction manual. Setting of the sink/source switch of the option should coincide with the setting of the inverter. If the setting differs, error trip of sink/source switching (E-10) will be actuated.

(4500) x 99.99% / 9999 x 80Hz / 80% = 45.00Hz Designation of input timing of binary/bcd data Input timing of the binary/bcd data can be designated from the binary/bcd input command (function number 86). Assign this function to the input terminals on the inverter. This function is validated by the input from the terminals not from the parameter operation command mode selection (cmod). By using this function, operation frequency of two or more inverters can be set successively by a single bit s setting circuit. Title Function Adjustment range Setting f111~118 Input terminal function selection to ,87 Input setting of 86 is positive logic and that of 87 is negative logic. Refer to the inverter s instruction manual. Cautions for 16bit binary input When using 16bit binary, note that resolution differs according to the parameter of point setting. 16bit resolution applies to the following setting, however the minimum setting resolution will be 0.01Hz for frequency and 0.01% for percentage. In case that the point conversion is selected to order than the following settings,13bit resolutions applies. In case that frequency point input is selected (for example of speed command selection).
