TRUE: Acceleration reduction active
MD is active only when MD32420 $MA_JOG_AND_POS_JERK_ENABLE = FALSE.
The settings in MD35220 $MA_ACCEL_REDUCTION_SPEED_POINT and MD35230
$MA_ACCEL_REDUCTION_FACTOR are always active for spindles (in spindle mode).
Remark:
This MD also influences the path motion with SOFT, BRISK, TRAFO

Description: When positioning a spindle that is not in position control mode from a high speed, the
position control is not activated until the spindle has reached or falls below the
velocity defined in MD35300 $MA_SPIND_POSCTRL_VELO.
The speed can be changed with FA[Sn] from the part program. Please refer to the
documentation:
/FB1/ Function Manual, Basic Functions; Spindles (S1), section "Spindle mode
'positioning operation" for a description of the spindle behavior under various
supplementary conditions (positioning from rotation, positioning from standstill).
Note:
The active speed from MD35300 $MA_SPIND_POSCTRL_VELO cannot exceed the max. speed set
in MD35135 $MA_GEAR_STEP_PC_MAX_VELO_LIMIT. If MD35135
$MA_GEAR_STEP_PC_MAX_VELO_LIMIT = 0, the value is limited to 90% of MD35130
$MA_GEAR_STEP_MAX_VELO_LIMIT.

Description: Positioning delay time.
After reaching the positioning end (exact stop fine), there is a waiting time equal to
the time set
in this MD. The position matching the currently set gear stage is selected.
