Stop responses
Faults with Safety Integrated Extended Functions and violation of limits can trigger the
following stop responses:
Table 5- 2 Overview, stop responses
Stop response Triggered ...
STOP A For all acknowledgeable
safety faults with pulse
disable.
STOP B Examples:
- standstill tolerance violated
in p9330/p9530 (SOS).
- Configured subsequent stop
p9363/p9563 for SLS.
- Subsequent response of
STOP F.
STOP C Configurable subsequent stop
p9363/p9563 with SLS.
STOP D Configurable subsequent stop
p9363/p9563 with SLS.
STOP F If a fault occurs in the
crosswise data comparison.
Follow-up response STOP B.
88
Action
Immediate pulse cancelation
Immediate input of speed
setpoint = 0 and start of timer
t
B.
Once t or n < n ,
B act shutdown
STOP A is triggered.
Immediate input of speed
setpoint = 0 and start of timer
t .
C
Once t has elapsed, SOS is
C
selected.
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
STOP B with subsequent STOP A.
The drive decelerates along the
OFF3 ramp and then switches to
STOP A.
The drive decelerates along the
OFF3 ramp; SOS is then selected.
The drive must be decelerated by
the higher-level control (within the
drive group)!
Once t has elapsed, SOS is
D
selected.
An automatic response is only
triggered if the standstill tolerance
window is violated in SOS.
If a safety function (SOS, SLS) has
been selected or if a hysteresis has
been configured for SSM, transition
to STOP A after t (Basic
F1
Functions) has elapsed or
STOP B after t (Extended
F2
Functions) has elapsed.
