Supplementary conditions

• Power ON
With Power ON no synchronized actions are
active.
However, static synchronized actions can be
activated on Power On with an asynchronized
subroutine (ASUP) started by the PLC.
• Mode change
Synchronized actions activated with the
vocabulary word IDS remain active following a
changeover in operating mode.
All other synchronized actions become inactive
following operating mode changeover (e.g. axis
positioning) and become active again following
repositioning and a return to automatic mode.
• Reset
With NC reset, all actions started by
synchronized actions are stopped. Static
synchronized actions remain active. They can
start new actions.
The RESET command can be used from the
synchronized action or from a technology cycle
to reset a modally active synchronized action. If
a synchronized action is reset while the
positioning axis movement that was activated
from it is still active, the positioning axis
movement is interrupted.
Synchronized actions of the WHEN type that
have already been executed are not executed
again following RESET.
