Information
DIN 2 and DIN 3 double allocation
Digital inputs DIN2 and DIN3 are used for 2 different functions:
1. for digital functions that can be parameterized (e.g. “enable left”),
2. for evaluation of an incremental encoder.
Both functions are coupled by an OR link.
Evaluation of an incremental encoder is always activated. This means that when an incremental encoder is
connected, make sure that the digital functions are switched off (parameter (P420 [-02] and [-03]) or with DIP
switch (chapter 4.2.2.2)).

Information
Rotation direction
The "counting direction" of the incremental encoder must correspond to the direction of rotation of the motor. If the
two directions are not identical, the connections of the encoder tracks (track A and track B) must be switched.
Alternatively, the resolution (line number) of the encoder can be set with a negative prefix in the P301 parameter.
Information
Encoder signal faults
Wires that are not required (e.g. track A inverse/B inverse) must be insulated.
Otherwise, if these wires come into contact with each other or the cable shield, short circuits can occur that can
cause encoder signal problems or destruction of the encoder.
