See MD35110 $MA_GEAR_STEP_MAX_VELO for more information.
Note:
● Programming a spindle speed which undershoots the lowest speed of the first gear
stage
MD35120
$MA_GEAR_STEP_MIN_VELO[1]
triggers a switch to the first gear stage.
Not relevant for:
● Programming of speed 0 (S0) if MD35120 $MA_GEAR_STEP_MIN_VELO[1] > 0

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 interpolatory 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.

Description: The maximum speed of the current gear stage for speed control mode (position 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.
