4)Sink logic type and source logic type

•The sink logic type is a logic where a signal turns 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 sig- nals.

•The source logic type is a logic where a signal turns on when a current flows into the corresponding signal input terminal.Terminal PC is common to the contact input signals. Terminal SE is common to the open col- lector output signals.

•Sink logic type

Using terminal PC as a common terminal prevents a malfunction caused by 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 a power supply in parallel in the outside of the inverter. Doing so may cause a malfunction due to undesir- able current.)
