[3] Order of priority for stop process
The order of priority for the Simple Motion module stop process is as follows.
Deceleration stop < Sudden stop < Immediate stop
(1) If the deceleration stop command ON (stop signal ON) or deceleration stop
cause occurs during deceleration to speed 0 (including automatic
deceleration), operation changes depending on the setting of "
Cd.42
Stop
command processing for deceleration stop selection".
(a) Manual control
Independently of the
Cd.42
setting, a deceleration curve is re-processed
from the speed at stop cause occurrence.
(b) OPR control, positioning control
When
Cd.42
= 0 (deceleration curve re-processing):
A deceleration curve is re-processed from the speed at stop cause
occurrence.
When
Cd.42
= 1 (deceleration curve continuation):
The current deceleration curve is continued after stop cause occurrence.
(For details, refer to Section 13.7.9 "Stop command processing for
deceleration stop function".)
(2) If the stop signal designated for sudden stop turns ON or a stop cause occurs
during deceleration, the sudden stop process will start from that point.
However, if the sudden stop deceleration time is longer than the deceleration
time, the deceleration stop process will be continued even if a sudden stop
cause occurs during the deceleration stop process.
