● The motor encoder must be connected to the associated power unit.
Component
Single Motor Module booksize
Double Motor Module booksize
Single Motor Module chassis
Power Module chassis
Note
If an additional encoder is connected to a Motor Module, it is assigned to this drive as
encoder 2 in the automatic configuration. At a Double Motor Module, an encoder at X201 is
assigned to the 2nd feedrate as 2nd measuring system.
