2 INSTALLATION AND WIRING 2.1 Pre-Installation Instructions Make sure that the input power of the inverter is off. CAUTION With input power on, do not install or remove the plug-in option. Otherwise, the inverter and plug-in option may be damaged.
INSTALLATION AND WIRING 2.2 Installation Procedure 1) Screw hole for option mounting Inverter side option connector Screw hole for option mounting (on earth plate) Hex-head screw for option mounting 2) 3) 1) Remove the inverter front cover. 2) Mount the hex-head screw for option mounting into the inverter screw hole (on earth plate). (size 5.5mm, tightening torque 0.56N⋅m to 0.75N⋅m) 3) Securely fit the connector of the plug-in option to the inverter connector along the guides.
INSTALLATION AND WIRING 2.3 Wiring (1) Strip off the sheath of the cable to wire. Strip off the sheath about the size below. If the length of the sheath pealed is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Wire the stripped cable after twisting it to prevent it from becoming loose. Cable stripping size In addition, do not solder it. Use a bar type terminal as required.
INSTALLATION AND WIRING (3) For wiring of the 30K(00620 (EC Version)) or less, route wires between the control circuit terminal block and front cover. If cables can not be routed between the control circuit terminal block and front cover due to the increased number of cables, remove a hook of the front cover and use a space become available. For wiring of the 37K(00770 (EC Version)) or more, use the space on the left side of the control circuit terminal block.

4 EXTENSION ANALOG OUTPUT 4.1 Wiring Example By setting the Pr. 306 to Pr. 312 values, analog signals such as the output frequency and output current can be output from the voltage output terminal (AM0) and current output terminal (AM1). Connect the voltmeter or ammeter as shown below: MCCB Power supply (Voltmeter) Inverter Motor IM + 0 to 10VDC FR-A7AY - (Ammeter) AM0 AM1 AMC + 0 to 20 mADC - CAUTION The wiring length between the FR-A7AY and the voltmeter/ammeter should be 10m maximum.

EXTENSION ANALOG OUTPUT 4.5 Adjustment Procedure 4.5.1 Setting of analog output signal voltage/current switchover (Pr. 309) Use Pr. 309 Analog output signal voltage/current switchover to select whether to output the same signal or different signals from terminal AM0 (voltage output) and terminal AM1(current output). Pr. 309 Setting 0 (initial value) 10 Description Terminal Parameters for Setting Same select signals are output from the voltage output terminal (AM0) and current output terminal (AM1).
EXTENSION ANALOG OUTPUT 4.5.2 Calibration of meter (1) Outputting the same select signals from terminals AM0 and AM1 (Pr. 309 = 0 or 10) START Connect a DC voltmeter (or DC ammeter) across terminals AM0 (or terminal AM1) and AMC. Use Pr. 323 (Pr. 324) to calibrate the meter when the voltage (current) input is 0. Set "21" (reference voltage output) in Pr. 306. At this time, check that the polarity is correct If the meter needle does not point to 0 when voltage or current input is 0, use Pr.
EXTENSION ANALOG OUTPUT (2) Outputting different select signals from terminals AM0 and AM1 (Pr. 309 = 1 or 11) START Connect a DC voltmeter (or DC ammeter) across terminals AM0 (or terminal AM1) and AMC. Use Pr. 323 (or Pr. 324) to calibrate the meter when the voltage (current) input is 0. Set "21" (reference voltage output) in Pr. 306 and Pr. 310.
EXTENSION ANALOG OUTPUT 4.5.3 Output signal setting Set the output signals to be monitored. Set Pr. 306 to output the same signal from terminals AM0 and AM1 and Pr. 306 and Pr. 310 to output different signals. For details of signal definitions, refer to Pr. 54 and Pr. 158 of the inverter manual (applied). Pr. 306/Pr.
EXTENSION ANALOG OUTPUT 4.5.4 Analog signal adjustment [Pr. 307, Pr. 308, Pr. 311, Pr. 312] Use Pr. 307 or Pr. 311 to set for zero analog output (meter points 0). In addition, use Pr. 308 or Pr. 312 to set for maximum analog output (full-scale). Use Pr. 307 to set the value for zero analog output and Pr. 308 for maximum analog output when outputting the same signal from terminals AM0 and AM1. Use Pr. 307(AM1) and Pr. 311(AM0) to set the value for zero analog output and Pr. 308(AM1) and Pr.
EXTENSION ANALOG OUTPUT 4.6 Instructions (1) A voltmeter having smaller internal impedance (or an ammeter having larger internal impedance) than the value indicated in the Specifications may not deflect to full-scale and may not be calibrated. (2) When calibrating a meter which has a small full-scale value, set the output of terminal AM0 (or AM1) to the minimum without the meter connected. Then, connect the meter and make calibration.
