FM output circuit

Pulse width T1: Adjust using calibration parameter C0

Pulse cycle T2: Set with Pr.55 (frequency monitor)

Not required when calibrating with operation panel.

Use a calibration resistor when the indicator (frequency meter) needs to be calibrated by a neighboring device because the indicator is located

far from the inverter.

However, the frequency meter needle may not deflect to full-scale if the calibration resistor is connected. In this case, use the resistor and

operation panel together.

In the initial setting, 1 mA full-scale and 1440 pulses/s terminal FM are used at 60 Hz.
