Request gear stage change
A gear stage change can be requested:
• in the part program using:
- M40 S...
Automatic gear stage selection to the programmed speed S...
- M41 ... M45
Direct selection of gear stages 1 ... 5
- M70
For MD35014 $MA_GEAR_STEP_USED_IN_AXISMODE = 1...5
(see "Configurable gear step in M70 [Page 1320]")
- G331 S...
For MD35010 $MA_GEAR_STEP_CHANGE_ENABLE, Bit 5 = 1
• in synchronized actions using:
- DO M40 S...
Automatic gear stage selection to the programmed speed S...
- DO M41... M45
Direct selection of gear stages 1 ... 5
- DO M70
For MD35014 $MA_GEAR_STEP_USED_IN_AXISMODE = 1...5
• through the PLC using the FC18 function block
• in the reset state through description of NC/PLC interface:
DB31, ... DBX16.0-16.2 (actual gear stage A to C)
The mechanically active gear stage can be communicated to the NC especially after a POWER ON.
Note
If the spindle motor is attached to the spindle directly (1:1) or with a non-variable
transmission ratio (MD35010 = 0), then the M40 and M41...M45 auxiliary functions are
not relevant to this spindle.
