Configuration using FCT
As a specification, the software end positions in FCT are
deactivated.
The specification of PNU 501:01 = PNU 501:02 = 0 will
deactivate the software end positions. However, the CMA X
limits setpoint specifications to the maximum or minimum
permissible end positions.
With the DGCI, the axis zero point cannot be edited.
