12.27.1 Parameter set switchover (up to SW 3)
Spindle parameter sets (NCK/SERVO)
8 parameter sets have been provided to date for spindles. A mechanical gear stage is
generally linked to these parameter sets, but is not a mandatory requirement.

MD
(PaSe=parameter set)
The switchover is implemented by means of the "Actual gear stage" control bits in the
cyclical, spindle-specific PLC interface (DB 31, DR K + 1, bits 0 - 2), i.e. the user can directly
select the active parameters via the PLC program.
In addition, the user also has an automatic gear stage selection function at his disposal which
works in the following way:
Speed ranges are defined by means of MD 403* - 410* and MD 411* - 418*. When a speed is
programmed by means of an S value, a setpoint gear stage (SGS) is output to the PLC which
is capable of evaluating it. After execution of the gear change, the setpoint gear stage can be
acknowledged through setting of the actual gear stage (AGS) and cancellation of the "Change
gear" signal (DB 31, DR K, bit 7).
