NC stop

Non-modal and modal synchronized actions (ID)
Traversing motions from non-modal and modal synchronized actions are stopped by NC stop.
While the channel is in the "interrupted" state (DB21, ... DBX35.6 == 1), a non-modal or modal
synchronized action remains active. If the condition is fulfilled during this time, all actions are
executed with the exception of traversing motions.
Stopped traversing motions are continued with NC start.
Static synchronized actions (IDS)
Whether traversing motions from static synchronized actions are stopped by NC stop depends
on which is controlling the command axis:
● NC controls axis (DB31, ... DBX28.7 == 0):
Traversing motions from static synchronized actions are stopped by NC stop.
● PLC controls axis (DB31, ... DBX28.7 == 1):
Traversing motions from static synchronized actions are not stopped by NC stop.
126
Aborted or inactive
The traversing motions are aborted
MD35040 $MA_SPIND_ACTIVE_AFTER_RESET = <value>
TRUE ⇒ The spindle remains active
FALSE ⇒ The spindle is stopped
MD20110 $MC_RESET_MODE_MASK, bit 13 = <value>
1 ⇒ The coupling remains active
0 ⇒ The coupling is released
