4.2.2 Wiring method of frequency inverter electric control circuit
Fig. 4-11 Wiring method of frequency inverter control circuit
Note:
1) The multi-function input terminal (DI1-DI6) can choose NPN or PNP transistor signal as input. The
internal power supply (+ 24V terminal) of frequency inverter or external power supply (24V) can be chose
as bias voltage.
2) The analog monitor output can be used for the input signal of the ammeter, voltmeter, etc. It can't be used
as feedback of control operation.
