Detailed Description
2.3 Configurable gear adaptation
The parameter sets of gear steps 1 to 5 can be configured with the following machine data:
MD35110 $MA_GEAR_STEP_MAX_VELO[n]
MD35120 $MA_GEAR_STEP_MIN_VELO[n]
MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT[n]
MD35140 $MA_GEAR_STEP_MIN_VELO_LIMIT[n]
MD35200 $MA_GEAR_STEP_SPEEDCTRL_ACCEL[n]
MD35210 $MA_GEAR_STEP_POSCTRL_ACCEL[n]
MD35012 $MA_GEAR_STEP_CHANGE_POSITION[n]
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
On stipulation of the servo parameter set by the VDI interface, parameter sets 1 to 6 can be
activated via indices 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.
Sequence for switchover
If the new gear step is preselected, the following sequence is implemented:
2-34
The parameter sets cannot be controlled.
The servo parameter set is defined primarily by the internal NC switchover at the VDI
interface.
