SGE to stop the drive
The following SGE are available to stop the drive:
Deselect ext STOP A (= SH deselec‐
tion)
Deselect ext. STOP C
Deselect ext. STOP D
Deselect ext. STOP E
Notes:
SGE " ... " = 1 stopping is not initiated (it is deselected)
SGE " ... " = 0 stopping is initiated (it is selected)
If a stop request is selected simultaneously using several SGEs, then that with the highest priority is
executed.
If one of these SGEs changes, the "tolerance time for SGE changeover" is activated (36950/p9550).
Feedback signals:
for SGE "Deselect ext. STOP A": via SGA "status pulses cancelled" and SGA "STOP A/B active"
for SGE "Deselect ext. STOP C": via SGA "STOP C active"
for SGE "Deselect ext. STOP D": via SGA "STOP D active"
for SGE "Deselect ext. STOP E": via SGA "STOP E active"
Note
● For external STOPs, alarms are not displayed. This means that the user himself must
configure the required message/signal.
