The emergency stop control element may only be reset as a result of manual manipulation of
the emergency stop control element. Resetting of the emergency stop control element alone
must not trigger a restart command.
A machine restart must be impossible until each of the actuated emergency stop control
elements has been deliberately reset by hand.
Emergency stop acknowledgement
1. Interface signal DB10, DBX56.2 (acknowledge emergency stop) = 1
2. Interface signal DB11, ... DBX0.7 (Mode Group reset) = 1
Note
Both interface signals:
DB10, DBX56.2 (acknowledge emergency stop)
and
DB21, ... DBX7.7 (Reset)
must remain set together until the interface signal:
DB10, DBX106.1(emergency stop active)
has been reset.
The emergency stop state cannot be reset with the interface signal DB21, ... DBX7.7
(Reset) alone.
