Meter calibration
(1) Outputting the same signal from terminals AM0 and AM1 (
Pr.309
= "0 or 10")
NOTE
• If calibration is performed without setting
Pr.306
= "21 (reference voltage output)", the terminal 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
After making adjustment with to deflect the meter to full-scale,
press to set.
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)
If the meter needle does not point to 0 when voltage or current input is 0,
use
Pr. 323
AM0: 0 V adjustment or
Pr. 324
AM1: 0 mA adjustment to
calibrate the meter
START
Use
Pr. 901
to perform adjustment, then set.
END
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
.
In
Pr. 306
, set the types of the signals to be output.
