*) The appropriate line must be specified separately for each parameter set according to the applicable syntax rules.
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:
• Feedback by NC:
46
DB31, ... DBX9.0 – DBB9.2 = 3 (controller parameter set)
– 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"
DB31, ... DBX69.0 – DBX69.2 = 3 (controller parameter set)
– The NC confirms/acknowledges the parameter-set changeover.
