MN-M 33,34: MN at motor zero point
The motor reference point is now evaluated (no MN initiator):
MN-M 33:
For a MN run, starting from the current position, the next motor zero point
in the negative travel direction is taken as the MN.
MN-M 34:
For a MN run, starting from the current position, the next motor zero point
in the positive travel direction is taken as the MN.

MN-M 35: MN at the current position
The current position when the MN run is activated is used as an MN.

MN-M 128/129: <Current_following error_threshold> when moving to
block
Without a MN (machine zero) initiator, an end of travel region (block) is used as
MN (machine zero).
For this the Stromschwelle> is evaluated if the drive pushes against the end of the
travel region. If the limit is exceeded, the MN is set. During the machine zero run
(MN), the error reaction "following error" is deactivated.
The homing offset must be set so that the home (reference point) for positioning
lies witihn the travel range.
MN-M 128:
Travel in the positive direction to the end of the travel region
MN-M 129:
Travel in the negative direction to the end of the travel region
