Preconditions
To allow an axis to be traversed from the control system, it is necessary to
supply enabling terminals on the drive and to set enabling bits on the interface.
The data block designated DBxx depends on the maximum configuration of the
machine axes currently validated for SINUMERIK 840Di.
