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: 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 Following error threshold is evaluated if the drive pushes against the
end of the travel region. If the limit is exceeded, the MN is set. During the homing
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
Caution!
Wrong settings can cause hazard for man and machine.
It is therefore essential to respect the following:
 Choose a low machine zero speed.
 Set the machine zero acceleration to a high value, so that the drive changes
direction quickly, the value must, however, not be so high that the limit threshold
is already reached by accelerating or decelerating (without mechanical limitation).
 The mechanical limitation as well as the load drain must be set so that they can
absorb the resulting kinetic energy.
