Functions and Connections of the Control Circuit Terminals
*1. Simultaneous input of current and voltage is not possible. Do not connect the signal lines simultaneously.
*2.
By factory default, multi-function output 11 is set to NO contact. To switch to NC contact, change the C031
setting.
*3. Do not input negative voltage. Doing so may result in damage to the inverter

If the multi-function input is set as the sink logic, the PCS
terminal acts as an external power supply input terminal.
If the multi-function input terminal is set as the source logic,
the PCS terminal acts as an internal power supply output
terminal.
