Mitsubishi FR - S500 instruction manual Str, RUN 24VDC

1) Sink logic type

In this logic, a signal switches on when a current flows out of the corresponding signal input terminal.

Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.

Connecting a positive external power supply for transistor output to terminal PC prevents a malfunction caused by a undesirable current. (Do not connect terminal SD of the inverter with terminal 0V of the external power supply. When using terminals PC-SD as a 24VDC power supply, do not install an external power supply in parallel with the inverter. Doing so may cause a malfunction in the inverter due to a undesirable current.)
