Attention

If there is shock in mechanism, the time delay is needed after
‘Stop’ operation.
 If alarm
happens with ‘stop’ command after push motion
executed,
change the ‘Push mode’ value
to bigger or smaller.

If the work can not be detect during Push position, the push
mode is automatically finished.
2) Specification
The push torque is different for each motor size. Refer to
「
3.3 Motor Torque
」
.
Push ratio (from 20~90[%] ) value is referenced to stop status torque on ‘Torque Graph’. And the
accuracy is -10 ~ +10[%].
