How to use the control circuit terminals
2) Source logic type
•
In this logic, a signal switches on when a current flows into the corresponding signal
input terminal.
Terminal PC is common to the contact input signals. For the open collector output
signals, terminal SE is a positive external power supply terminal.
•
Use terminal SD as a common terminal,
and perform wiring as shown on the right.
(Do not connect terminal PC of the inverter
with te24V 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
undesirable currents.)
