Changeover
In order to switch over the position-control gain, the PLC user program selects the 4th parameter set for machine
axis X1.
• Request by PLC user program:
DB31, ... DBX9.0 – DBX9.2 = 3 (parameter set servo)
- A request to change over to the 4th parameter set is sent for machine axis AX1.
- The parameter set is changed over once a delay has elapsed.
- Parameter set 4 is now active, in accordance with machine data with index "3"
• Feedback by NC:
DB31, ... DBX69.0 – DBX69.2 = 3 (parameter set servo)
- The NC confirms/acknowledges the parameter-set changeover.
