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
n Transistor Input Signal Using 0 V Common/Sink Mode
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.
