When operation panel (FR-DU04) is used
8) Press the key to stop the inverter.
1) Select the PU operation mode.
2) Set the running frequency.
3) Press the key.
4) Read Pr. 900 "FM terminal calibration" or Pr. 901 "AM terminal calibration".
5) Press the key to run the inverter. (Motor need not be connected.)
7) Press the key for about 1.5 seconds.
6) Hold down the key to adjust the meter pointer to the required position.

REMARKS
Calibration can also be made for external operation. Set the frequency in the external operation mode and
make calibration in accordance with steps 4) to 8).
Note: 1. Pr. 900 is factory-set to 1mA full-scale or 1440 pulses/s FM output frequency at 60Hz. The
maximum pulse train output of terminal FM is 2400 pulses/s.
2. When a frequency meter is connected across terminals FM-SD to monitor the running frequency,
the FM terminal output is filled to capacity at the factory setting if the maximum output frequency
reaches or exceeds 100Hz. In this case, the Pr. 55 setting must be changed to the maximum
frequency.
3. For the operation procedure using the parameter unit (FR-PU04), refer to the FR-PU04
instruction manual.
4. Calibration can also be made during operation.
