Phase 4, 4a
The spindle is stationary and it has reached the position. The position control is active and stops the spindle in
the programmed position.
NC/PLC IS:
DB31, ... DBX60.6 (Position reached with exact stop coarse)
and
DB31, ... DBX60.7 (Position reached with exact stop fine)
are set if the distance between the spindle actual position and the programmed position (spindle setpoint
position) is less than the settings for the exact stop fine and coarse limits.
This is defined in the machine data:
MD36010 $MA_STOP_LIMIT_FINE
MD36000 $MA_STOP_LIMIT_COARSE
Phase 3:
At the point, which is determined by the braking start point calculation in Phase 2, the spindle decelerates to a
standstill with the acceleration given in the following machine data:
MD35210 $MA_GEAR_STEP_ POSCTRL_ACCEL
Phase 4:
The spindle is stationary and it has reached the position. The position control is active and stops the spindle in
the programmed position.
NC/PLC IS:
DB31, ... DBX60.6 (Position reached with exact stop coarse)
and
DB31, ... DBX60.7 (Position reached with exact stop fine)
are set if the distance between the spindle actual position and the programmed position (spindle setpoint
position) is less than the settings for the exact stop fine and coarse limits.
This is defined in the machine data:
MD36010 $MA_STOP_LIMIT_FINE
MD36000 $MA_STOP_LIMIT_COARSE
