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.
Prerequisites
Parameter-set changeover must be enabled:
MD35590 $MA_PARAMSET_CHANGE_ENABLE [AX1] = 1 or 2
The 1st parameter set for machine axis X1 is set, in accordance with machine data with
index "0" NC/PLC interface:
DB31, DBB9.0 – DBB9.2 = 0
Parameter-set-dependent machine data
Parameter-set-dependent machine data are set as follows:
