Stop responses

Faults with Safety Integrated Extended Functions and violation of limits can trigger the
following stop response:

Action
Immediate pulse suppression
Immediate input of speed set-
point = 0 and start of timer t
Once t or n < n has
B act shutdown
expired, STOP A is triggered.
Immediate input of speed set-
point = 0 and start of timer t
Once t has elapsed, SOS is
C
selected.
Timer t starts.
D
No drive-integrated response.
SOS is activated on expiration
of t .
D
Effect
Drive coasts down
STOP B with subsequent STOP A.
The drive decelerates along the OFF3
B .
ramp and then switches to STOP A.
N o te:
For "SS1 with external stop" (SS1E),
braking is n o t along the OFF3 ramp
(see Section "Safe Stop 1 with external
stop (Page 90)")
The drive decelerates along the OFF3
. ramp; SOS is then selected.
C
The drive must be decelerated by the
higher-level controller (within the drive
group)!
Once t has elapsed, SOS is selected.
D
An automatic response is only trig-
gered if the standstill tolerance window
is violated in SOS.
