12.27 Parameter set switchover
The Parameter set switchover function
is as option (SW 4 and higher).
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.
Axis parameter
1stPaSe 2ndPaSe
Parameter
Servo gain factor 252* 1320*
Feed forward control factor 312* 1260*
Time const. symm. filter 392* 1324*
MD
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.
