35122 GEAR_STEP_MIN_VELO2
rev/min 2nd data set: Minimum speed for gear stage change
CTEQ
- 6
Description: The minimum speed (lower switching threshold) of the gear stage for automatic
gear stage change M40 G331 S.. is set in GEAR_STEP_MIN_VELO2 for interpola-
tory tapping G331, G332. The speed ranges of the gear stages must be defined
so that there are no gaps between them or they can overlap.
The 2nd gear stage data block for tapping with G331/G332 is activated with
MD35010 $MA_GEAR_STEP_CHANGE_ENABLE bit 5 for the master spindle.
Related to:
MD35112 $MA_GEAR_STEP_MAX_VELO2 (maximum speed for 2nd data block gear stage
change)
MD35092 $MA_NUM_GEAR_STEPS2 (number of gear stages 2nd gear stage data block)
MD35010 $MA_GEAR_STEP_CHANGE_ENABLE (gear stage change, 2nd data block is
possible)
MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT (maximum speed of gear stage with speed
control)
MD35135 $MA_GEAR_STEP_PC_MAX_VELO_LIMIT (maximum speed of gear stage with
position control)
MD35140 $MA_GEAR_STEP_MIN_VELO_LIMIT (min. speed of gear stage)
35130 GEAR_STEP_MAX_VELO_LIMIT
rev/min Maximum speed of gear stage
CTEQ

The maximum speed of the current gear stage for speed control mode (position
Description:
control not active) is configured in MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT.
The speed setpoints generated taking the override into account are limited to
this speed.

The configured speed cannot exceed the value from MD35100
$MA_SPIND_VELO_LIMIT.
If position control is active for the spindle, the speed is limited to
the maximum speed of MD35135 $MA_GEAR_STEP_PC_MAX_VELO_LIMIT.
The NC/PLC interface signal "Setpoint speed limited" is set to indicate
that the speed is being limited.
The maximum speed entered here has no effect on the automatic gear stage
selection M40 S..
The upper switching threshold for the automatic gear stage selection M40
is configured in MD35110 $MA_GEAR_STEP_MAX_VELO.
