●
Gear stage change at defined spindle position. After reaching the position
configured in MD35012 $MA_GEAR_STEP_CHANGE_POSITION, there is a waiting period
equal to the time specified here. After expiry of this time, the position control
is switched off for an active direct measuring system, and the NC/PLC interface
signals DB390x DBX2000.3 (Change gear) and DB390x DBX2000.0 - .2 (Setpoint gear
stage A-C) are output.

Block search upon the output of an accumulated positioning block (SPOS, SPOSA, M19).
35350 SPIND_POSITIONING_DIR
- Direction of rotation when positioning
CTEQ
- -
Description:
When SPOS or SPOSA is programmed, the spindle is switched to position control mode and
accelerates with the acceleration defined in MD35210 $MA_GEAR_STEP_POSCTRL_ACCEL
(acceleration in position control mode) if the spindle is not synchronized. The
direction of rotation is defined by MD35350 $MA_SPIND_POSITIONING_DIR (direction of
rotation for positioning from standstill).
MD35350 $MA_SPIND_POSITIONING_DIR = 3 ---> Clockwise direction of rotation
MD35350 $MA_SPIND_POSITIONING_DIR = 4 ---> Counterclockwise direction of rotation
Related to:
MD35300 $MA_SPIND_POSCTRL_VELO (position control activation speed)
35400 SPIND_OSCILL_DES_VELO
rev/min Oscillation speed
CTEQ
- -
Description:
During oscillation, the NC/PLC interface signal DB380x DBX2002.5 (Oscillation speed)
is used to select a motor speed for the spindle motor. This motor speed is defined in
MD35400 $MA_SPIND_OSCILL_DES_VELO. The motor speed defined in this MD is independent
of the current gear stage. In the AUTOMATIC and MDI displays, the oscillation speed is
displayed in the "Spindle setpoint" window until the gear is changed.
MD irrelevant to:
All spindle modes except oscillation mode
Special cases:
The acceleration during oscillation (MD35410 $MA_SPIND_OSCILL_ACCEL) is valid for the
oscillation speed defined in this MD.

35410 SPIND_OSCILL_ACCEL
rev/s² Acceleration during oscillation
CTEQ
- -
Description:
The acceleration specified here is only effective for the output of the oscillation
speed (MD35400 $MA_SPIND_OSCILL_DES_VELO) to the spindle motor. The oscillation speed
is selected using the NC/PLC interface signal DB380x DBX2002.5 (Oscillation speed).
MD irrelevant to:
All spindle modes except oscillation mode
