Gear ratios
Each gear stage has a parameter set assigned to it in the drive, with
the index of
the parameter ParSet [ ] corresponding to the previously
defined gear stage GearStep [ ].
The following applies: GearStep[1] → ParSet[1], GearStep[2] → Par‐
Set[2]
Configuring gear switching in the
drive
Gear switching must
also be configured in the drive itself. This can be achieved
in the "Parameter Set Switching" dialog in the IndraWorks-Drive. The number
of parameter blocks (1) and the parameter groups (2) are directly specified by
the CNC. The parameter block can be copied by clicking on the "Copy param‐
eter set 0 to" button (3).
Fig.7-22: Configuring parameter block switching
The "Activation of drive-controlled
parameter block switching"
checkbox may not be activated.
We recommend that you proceed as follows to commission a gear:
1. Enter the data of the gear stages in the NC configuration.
2. Program the gear switching in the PLC.
3.
Commission the spindle motor in gear stage 1 (optimize, if necessary).
4. Copy parameter block 0 (gear stage 1) to parameter block 1. Then turn
off/on.
5. Switch the gear to gear stage 2 (e.g., M42).
6. Commission the spindle motor in gear stage 2 (optimize).
Repeat steps 4 to 6 for each gear stage.
For more information on gear switching in the PLC, please refer to
the MTX-PLC-CNC Interface description.
