MN-M 5,6: MN-Initiator = 1 on the negative side
The MN initiator can be positioned at any location within the travel range. The
travel range is then divided into 2 contiguous ranges: one range with deactivated
MN initiator (positive part of the travel range) and one range with activated MN
initiator (negative part of the travel range).
When the MN initiator is inactive (signal = 0) the search for the machine reference
is in the negative travel direction.
MN-M 5: The first motor reference point is used as MN with MN initiator = "0".
MN-M 6: The first motor reference point is used as MN with MN initiator = „1“.

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