Parameter set changeover
A parameter-set changeover is performed to change the position-control gain (servo gain factor) for machine axis
X1 from v = 4.0 to Kv = 0.5.
Preconditions
The parameter set changeover must be enabled by the machine data:
MD35590 $MA_PARAMSET_CHANGE_ENABLE [AX1] = 1 or 2 (parameter set change possible)
The 1st parameter set for machine axis X1 is set, in accordance with machine data with index "0" NC/PLC
interface:
DB31, … DBX9.0 - DBX9.2 = 0 (controller parameter set)
Parameter-set-dependent machine data
Parameter-set-dependent machine data are set as follows:
