MN-M 35: MN at the current position
The current position when the MN run is activated is used as an MN.
35
MN-M 128/129: Rising of current while moving to block
Without an MN initiator, an end of travel region (block) is used as an MN.
The increase in the current is evaluated for this purpose (adjustable up to 100% of
the reference current), if the motor is pressing against the end of the travel region.
If the limit is exceeded, the MN is set. Tracking error is deactivated during the MN
run.
The machine zero offset must be set so that the zero point (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 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 current 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.
