(2) 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 Pr. 900 to set
END
In Pr. 306 and Pr. 310, set the types of the signals to be output.
NOTE
• If calibration is performed without setting "21 (reference voltage output)" in Pr.306 or Pr.310, the 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 point to 0 when voltage or current input is 0,
use Pr. 323 AM0 for 0 V adjustment or Pr. 324 AM1 for 0 mA adjustment of
the meter
At this time, the following analog signal is actually output and deflects the meter.
<across terminals AM0-AMC>
Maximum output voltage set previously (factory setting: 10 VDC)
<across terminals AM1-AMC>
Maximum output current set previously (factory setting: 20 mADC)
Terminal AM1
After making adjustment with
Use Pr. 901 to set
press
to deflect the meter to full-scale,
to set.
