MN-M 132, 133: Determine absolute position via distance coding with directi-
on reversal switches
Only for motor feedback with distance coding (the absolute position can be deter-
mined via the distance value).
Compax3 determines the absolute position from the distance of two signals and
then stops the movement (does not automatically move to position 0).

Adjusting the machine zero proximity switch
This is helpful in some cases with homing modes that work with the home switch
and motor reference point.
If the motor reference point happens to coincide with the position of the MN initia-
tor, there is a possibility that small movements in the motor position will cause the
machine reference point to shift by one motor revolution (to the next motor referen-
ce point).

A solution to this problem is to move the MN initiator by means of software. This is
done using the value initiator adjustment.
