<Setting>

Refer to the above diagrams and set the frequency monitoring reference value in Pr. 55 and the current monitoring reference value in Pr. 56.

Pr. 55 is set when Pr. 54 "FM (AM) terminal function selection" = "0" and Pr. 56 is set when Pr. 54 = "1".

Set the Pr. 55 and Pr. 56 values so that the output pulse train output of terminal FM is 1440 pulses/s (the output voltage of terminal AM is 5V).

CAUTION

•The maximum pulse train output of terminal FM is 2400pulses/s. If Pr. 55 is not adjusted, the output of terminal FM will be filled to capacity. Therefore, adjust Pr. 55.

•The maximum output voltage of terminal AM is 5VDC.

2.7 Restart Operation Parameters

2.7.1 Restart setting

At power restoration after an instantaneous power failure, you can restart the inverter without stopping the motor (with the motor coasting).
