Fig. 2-2 Positioning from rotation
Note
The speed from machine data:
MD36302 $MA_ENC_FREQ_LOW
must be greater than the position-control activation speed
(MD35300 $MA_SPIND_POSCTRL_VELO).
Phase 1
Possible positioning from Phase 1a:
The spindle is rotating at a higher speed than the encoder limit frequency. The spindle is not
synchronized.
Possible positioning from Phase 1b:
The spindle is rotating at a lower speed than the encoder limit frequency. The spindle is
synchronized.
Note
If position control is active, the speed can only amount to 90% of the maximum speed of the
spindle or the encoder limit frequency (10% control reserve required).
