Stop responses
Faults with Safety Integrated Extended Functions and violation of limits can trigger the
following stop responses:
Table 6- 2 Overview, stop responses
Stop response Triggered ... Action Effect
STOP A For all acknowledgeable
safety faults with pulse
disable.
Immediate pulse cancelation Drive coasts down
STOP B Examples:
- standstill tolerance violated
in
p9330/p9530 (SOS).
- Configured subsequent stop
p9363/p9563 for SLS.
- Subsequent response of
STOP F.
Immediate input of speed
setpoint = 0 and start of timer
t
B .
Once t
B
or n
act
< n
shutdown
,
STOP A is triggered.
STOP B with subsequent STOP A.
The drive is braked along the OFF3
ramp and then switches to STOP A.
STOP C Configurable subsequent stop
p9363/p9563 with SLS.
Immediate input of speed
setpoint = 0 and start of timer
t
C
.
Once t
C
has elapsed, SOS is
selected.
The drive decelerates along the
OFF3 ramp; SOS is then selected.
STOP D Configurable subsequent stop
p9363/p9563 with SLS.
Timer t
D
starts.
No drive-integrated response.
SOS is activated on expiration
of t
D
.
The drive must be decelerated by
the higher-level control (within the
drive group)!
Once t
D
has elapsed, SOS is
selected.
An automatic response is only
triggered if the standstill tolerance
window is violated in SOS.
STOP F If a fault occurs in the
crosswise data comparison.
Follow-up response STOP B.
Timer t
F1
(Basic Functions) or
t
F2
(Extended Functions)
No drive response
If a safety function (SOS, SLS) has
been selected or if SSM with
hysteresis has been enabled,
transition to STOP A after t
F1
(Basic
Functions) has elapsed or STOP B
after t
F2
(Extended Functions) has
elapsed.
