Calibration of meter
START
Connect a DC voltmeter across terminals AM1
and 5.
Calibrate the meter at zero voltage output
using Pr.323.
Set "21" (reference voltage output) in Pr.306.
Use C1 (Pr.901) to perform adjustment, then set.
END *1

Specify the output signal by setting Pr.306. (Refer to
NOTE
• If calibration is performed without setting Pr.306 = "21 (reference voltage output)", terminal AM of the inverter is calibrated.
To calibrate extended analog output, always set to "21".
• When the plug-in option is remounted on another inverter, use Pr.323 to calibrate again.
At this time, check that the polarity is correct
If the meter needle does not indicate zero when the voltage input is at zero,
calibrate the meter using Pr.323.
At this time, the following analog signal is actually output and deflects the meter.
<Between terminals AM1 and 5>
Maximum output voltage set previously (factory setting: 10 VDC)
Make adjustment with the setting dial or the UP/DOWN key to deflect
the meter needle to full-scale, then press the SET key to set.
