Sinking/Sourcing Mode Switch

Set the DIP switch S3 on the front of the drive to switch the digital input terminal logic between sinking mode and sourcing mode; the drive is preset to
sinking mode.
Set Value
SINK
SOURCE
Transistor Input Signal Using 0 V Common/Sink Mode
n
When controlling the digital inputs by NPN transistors (0 V common / sinking mode), set the DIP switch S3 to SINK and use the internal 24 V power
supply.
Transistor Input Signal Using +24 V Common/Source Mode
n
When controlling digital inputs by PNP transistors (+24 V common / sourcing mode), set the DIP switch S3 to SOURCE and use an external 24 V power
supply.
