10.1.4 Limit Switch Specifications
Type Optical sensor
Supply voltage +5 V / ground
Signal output Open collector
Signal logic The signal level changes when passing the limit switch. The signal logic
is active high. That means:

Normal motor operation: low (0 V)
 Limit switch reached: high (+5 V)
10.1.5 Reference Switch Specifications
Type Optical sensor
Supply voltage +5 V / ground
Signal output Open collector
Signal logic Direction sensing by means of different signal levels on the left and
right side of the reference point switch: The signal level changes from 0
to +5 V when the reference point switch is passed.
