Pulse encoder connection principles
Two different encoder connections are available.
1. Differential connection; only pulse encoders generating voltage signals can be used.
2. Single-ended (push pull) connection; only pulse encoders generating voltage signals can be used.
Pulse encoder connection principles:
In case of single ended encoders jumpers J4A ... J4C have to be set to a neutral position according
to the table below.
To get a threshold lower than 5 V each terminal XENC:1, 3 and 5 must be connected via a resistor R
to GND.
