Parameter set changeover from the parts program
For parameter-set changeover from the parts program, the user (machine manufacturer)
must define corresponding user-specific auxiliary functions and evaluate them in the PLC
user program. The PLC user program will then set the changeover request on the
corresponding parameter set.
For detailed information about auxiliary function output, please refer to:

DB31, ... DBX9.3 (disable parameter-set default setting by NC)
Parameter-set changeover request will be ignored.

Signals from axis/spindle
DB31, ... DBX61.0 (drive test travel request)
If machine axes are traversed by special test functions such as "function generator", an
explicit drive-test-specific enable is requested for the movement:
DB31, ... DBX61.0 == 1 (drive test travel request)
The movement is carried out once the movement is enabled:
DB31, ... DBX1.0 == 1 (drive test travel enable)
DB31, ... DBX61.3 (follow-up mode active)
The machine axis is in follow-up mode.
DB31, ... DBX61.4 (axis/spindle stationary)
"Axis/spindle stationary" is set by the NC if:
•
No new setpoints are to be output AND
•
The actual speed of the machine axis is lower than the parameterized zero speed:
MD36060 $MA_STANDSTILL_VELO_TOL (threshold velocity axis stationary)
DB31, ... DBX61.5 (position controller active)
The machine axis position control loop is closed and position control is active.
DB31, ... DBX61.6 (speed controller active)
The machine axis speed control loop is closed and speed control is active.
