The speed limitations are configured only once for each gear stage with the following machine data,
independently of the different switching thresholds:
For tapping without compensating chuck (G331, G332) the speed can be limited to the linear acceleration range
of the motor additionally. For this, the maximum speed of the linear motor characteristics range is specified in the
following machine data as a function of the gear stage:
MD35550 $MA_DRILL_VELO_LIMIT[n]
Specify gear stage in the part program
Automatic selection with active M40
The gear stage is automatically selected by the control. The gear stage in which the programmed spindle speed
(
S...
) is possible is checked in this context. If a gear stage results from this that is not equal to the current
(actual) gear stage, then the following NC/PLC interface signals are set:
DB31, ... DBX82.3 (change over gear stage)
DB31, ... DBX82.0-82.2 (setpoint gear stage A to C)
While the appropriate gear stage is being determined, a gear stage change is only requested if the new speed is
not within the permissible speed range of the active gear stage.
The speed is limited to the maximum speed of the current gear stage or raised to the minimum speed of the
current gear stage and the appropriate NC/PLC interface signal is set:
DB31, ... DBX83.1 (Setpoint speed restricted)
DB31, ... DBX83.2 (Setpoint speed restricted)
Machine data
Meaning
MD35112 $MA_GEAR_STEP_MAX_VELO2[n]
Maximum speed for automatic gear stage
change
MD35122 $MA_GEAR_STEP_MIN_VELO2[n]
Minimum speed for automatic gear stage
change
MD35212 $MA_GEAR_STEP_POSCTRL_ACCEL2[n]
Acceleration in position control mode
Note
The number of servo parameter sets concerning the mechanical factors remain unchanged.
Furthermore, five mechanical gear stages for the spindle and one for the axis operation can
be configured.
