Safety faults

Stop responses
Faults with Safety Integrated Extended Functions and violation of limits can trigger the
following stop response:
Table 8- 7 Stop response overview
Stop Triggered ...
response
STOP A For all acknowledgeable safety
faults with pulse suppression.
As a follow-up reaction of STOP
F.
STOP B Examples:
- standstill tolerance violated in
p9330/p9530 (SOS).
- Configured subsequent stop
p9363/p9563 for SLS.
- When the SS2 function is
active
stop F results in
follow-up stop B.
STOP C Configured subsequent stop
p9363/p9563 with SLS.
When SLS is selected, the drive
is decelerated with Stop C.
STOP D Configured subsequent stop
p9363/p9563 with SLS.
STOP F If a fault occurs in the crosswise
data comparison.
Follow-up response STOP B.
Note
A delay time between STOP F and STOP B should only be set if an additional response is
initiated during this time when the "Internal Event" (p9722.7) message signal is evaluated.
A monitoring function should also always be active even in automatic mode (e.g. SLS with a
high limit speed) when the delay time is used.

Action
Immediate pulse suppression
Immediate input of speed
setpoint = 0 and start of timer t
STOP A is triggered on
expiration of t or if n <
B act
n .
shutdown
Immediate input of speed
setpoint = 0 and start of timer t
SOS is activated on expiration
of t .
C
Timer t starts
D
No drive-integrated response
SOS is activated on expiration
of t .
D
Timer t (Basic Functions) or
F1
t (Extended Functions)
F2
No drive response
Effect
Drive coasts down
The drive brakes down along the
OFF3 ramp and then goes into STOP
B
A state
The drive brakes down along the
OFF3 ramp, SOS is then activated
C
The drive must be decelerated by the
higher-level control (within the drive
group)!
SOS is activated on expiration of the
time t .
D
An automatic response is only
triggered if the standstill tolerance
window is violated in SOS.
If a safety function (SOS, SLS) is
active, transition to STOP A state on
expiration of t (Basic Functions), or
F1
to STOP B state on expiration of t
(Extended Functions).
