12.27.2 Parameter set switchover with SW 4 and higher (option)

"Position control" parameter group

The structure of the "Position control" parameter group is identical for axes and spindles.

This parameter group contains the parameters "Servo gain (Kv) factor", "Feedforward control
factor" and "Time constant symmetrizing filter" which were previously switched over for axes
by means of thread functions. With software versions up to SW 3, switchover from parameter
set number 1 to parameter set number 2 is implemented automatically for the thread function.
This functionality is not affected by selection of the extended parameter set switchover.

The parameters in the "Position control (PCtr)" group are listed below. When the extended
parameter set switchover function is selected via MD bits, all the parameters in this group can
be switched over.
