12.27 Parameter set switchover

12.27 Parameter set switchover
The parameter set switchover function allows parameters of various NC control areas (position
control, actual value detection) or of the drive to be switched over simultaneously and with
minimum delay.
12.27.1

Parameter set switchover (up to SW 3)

Axis parameter sets (NCK/SERVO)

Two parameter sets (PaSe) are available for the position control area in feed axes.
Parameter
Servo gain factor
Feed forward control factor
Time const. symm. filter
The switchover is executed implicitly when G functions for thread functions (G33, G34, G35,
G36, G63) are selected. There is no way in which the user can directly initiate the switchover
process.
