Outputting separate 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.

Terminal AM0

Use C0 (Pr.900) to set

In Pr.306 and Pr.310, set the types of the signals to be output. (Refer to

NOTE

• If calibration is performed without setting "21 (reference voltage output)" in Pr.306 or Pr.310, terminal FM, CA, or AM of the

inverter is calibrated. To calibrate the extended analog output, always set to "21".

• When the plug-in option used was remounted on another inverter, use Pr.323 and Pr.324 to calibrate again.

At this time, check that the polarity is correct.

If the meter needle does not indicate zero when the voltage or current

input is at zero, calibrate the meter using Pr.323 AM0 0 V adjustment

or Pr.324 AM1 0 mA adjustment.

At this time, the following analog signal is actually output and deflects the meter.

Maximum output voltage set previously (factory setting: 10 VDC)

Maximum output current set previously (factory setting: 20 mADC)
