Detailed Description
2.3 Configurable gear adaptation
Note
The number of servo parameter sets for the mechanical factors remain unchanged.
Furthermore, five mechanical gear steps for the spindle and one for the axis operation can
be configured.
As the speed limits of each gear step are dependent on the mechanical factors, the following
machine data can be configured only for one gear step data set for each gear step:
MD35130 $MA_GEAR_STEPMAX_VELO_LIMIT[n] ; Limit of maximum speed
MD35130 $MA_GEAR_STEPMAX_VELO_LIMIT[n] ; Increase to the minimum speed for M3,
M4
Changing parameter sets and formatting
The gear step change also switches over the servo parameter set,
if machine data:
MD35590 $MA_PARAMSET_CHANGE_ENABLE = 0 or 1
.
0:
1:
If the parameter sets cannot be controlled:
• For axes, the 1st parameter set with the index 0 is always the one that is applicable.
• For spindles, the 2nd to the 6th parameter set plus one is always active depending on the
By pre-setting of servo parameter set through VDI interface, the parameter sets 1 to 6 can
be activated with the index 0 to 5.
The following applies:
• For the axes involved, the parameter set number that corresponds to the master spindle
• For spindles, the 2nd to the 6th parameter set plus one is always active depending on the
If:
MD35590 $MA_PARAMSET_CHANGE_ENABLE = 2,
the servo parameter set is specified by the PLC.
A gear step can be specified by the PLC at any time.

The parameter sets cannot be controlled.
The servo parameter set is defined primarily by the internal NC switchover at the VDI
interface.
