FDD parameter sets (611D)
There is no selection of parameter sets available for feed drives. The PLC control and status
signals (DB 29, DW K + 122, bits 0 - 2; DB 29, DW K + 120, bits 0 - 2) have no effect, but
are still transferred.
MSD parameter sets (611D)
A selection of eight parameter sets is available for a main spindle drive via the PLC control
signals DB31, DW K + 74, bits 0 - 2. The active parameter set is displayed via status signals
DB 31, DW K + 72, bits 0 - 2. The MSD parameter set and NCK gear stages can be linked by
means of bit 4 in MD 522*. If the bit is reset, then the MSD parameter set is switched over
with the NCK actual gear stage. In this case, control bits DW K + 74 have no effect.
