3.3.1 Setting the Operating Mode
The three possible operating modes are selected with DIP switch S1. The settings apply to sym-
metrical and asymmetrical operation.
The encoder provides two pulse trains displaced by 90° in relation to each other:
Setting of DIP switch S1:
Closed contacts (x):
One count pulse evaluated
Two count pulses evaluated
Four count pulses evaluated
The encoder provides neutral pulses (1 pulse train, 1 direction signal):
Pulse
Forward direction
Backward direction
Setting of DIP switch S1:
Closed contacts (x)
The encoder provides direction–sensitive pulses (one pulse per direction):
– Forward pulse
– Backward pulse
Setting of DIP switch S1:
Closed contacts (x)
The specification of the synchronization direction (drive direction) is made by DIP switch S2:
Setting of DIP switch S2:
Contact 1 closed:
Contact 1 open:
