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:
Machine data
MD32200 $MA_POSCTRL_GAIN [0, AX1] = 4.0
MD32200 $MA_POSCTRL_GAIN [1, AX1] = 2.0
MD32200 $MA_POSCTRL_GAIN [2, AX1] = 1.0
MD32200 $MA_POSCTRL_GAIN [3, AX1] = 0.5
MD32200 $MA_POSCTRL_GAIN [4, AX1] = 0.25
MD32200 $MA_POSCTRL_GAIN [5, AX1] = 0.125
MD31050 $MA_DRIVE_AX_RATIO_DENOM [0, AX1] = 3
MD31050 $MA_DRIVE_AX_RATIO_DENOM [1, AX1] = 3
MD31050 $MA_DRIVE_AX_RATIO_DENOM [2, AX1] = 3
MD31050 $MA_DRIVE_AX_RATIO_DENOM [3, AX1] = 3
MD31050 $MA_DRIVE_AX_RATIO_DENOM [4, AX1] = 3
MD31050 $MA_DRIVE_AX_RATIO_DENOM [5, AX1] = 3
MD31060 $MA_DRIVE_AX_RATIO_NUMERA [0, AX1] = 5
MD31060 $MA_DRIVE_AX_RATIO_NUMERA [1, AX1] = 5
MD31060 $MA_DRIVE_AX_RATIO_NUMERA [2, AX1] = 5
MD31060 $MA_DRIVE_AX_RATIO_NUMERA [3, AX1] = 5
