Fig. 97: Wiring of the same sensor for all drives (supplied from an external 24V)
If a sensor is supplied from the I/O board of the drive and the diodes are connected between
terminals 12 and 17, the digital inputs must be isolated from the ground. Set the isolation
DIP switch to Float.
The digital inputs are active when they are connected to GND, which is the default condition.
