Pr. 901 "AM terminal calibration"
z By using the control panel or parameter unit, you can calibrate a meter connected to
terminal AM to full scale deflection.
z Terminal AM is factory-set to provide a 10VDC output in the full-scale state of each
monitored data.
according to the meter reading. Note that the maximum output voltage is 10VDC.
(1)Calibration of terminal AM
1) Connect a 0-10VDC meter (frequency meter) across inverter terminals AM-5.
(Note the polarity. AM is the positive terminal.)
2) Set any of "0, 1, 2" in Pr. 158.
When the running frequency or inverter output current has been selected as the
output signal, preset in Pr. 55 or Pr. 56 the running frequency or current at which
the output signal is 10V.
Pr. 901 allows the output voltage ratio (gain) to be adjusted
