Parameter set switchover with SW 4 and higher (option)

The parameters to be switched over are divided into 3 parameter groups (PaGr) in the control.
The individual parameter groups are switched over independently of one another. Each
parameter group contains 8 identically formatted parameter sets (PaSe). A specific parameter
set within a PaGr can be selected by specifying a parameter set number (PaSNo) from the
PLC.
Owing to the grouping of parameters according to type and the fact that they can be switched
over independently, the system is highly flexible in terms of configuration and adaptation of the
control to the mechanical features, dynamic response and geometry of the machine
The extended parameter set switchover must be enabled explicitly via MD 1828*, bit 0 (axes)
or MD 523*, bit 0 (spindles).
The switchover mechanisms for axes and spindles available to date which are described above
remain fully functional.
The automatisms used to date (Spindle: Switchover via S program commands; axis:
Switchover through G program commands) remain operative even when the extended
parameter set switchover is enabled. They are, however, converted to the new parameter
groups, i.e. where previously all parameters were switched over with the gear change, a
switchover request (new setpoint gear stage = new parameter set numbers) is now set for all
parameter groups which contain these parameters.
