SBC usage
Sets how the mechanical brake is used to-
gether with the STO function. Mechanical
brake usage is always coupled with the
STO function.
Delayed brakeSTO SBC usageSBC.11
In this manual, it is assumed that you do
not use a mechanical brake. Instead, the
SBC function is used to control the auxiliary
safety relay(s) which is connected to the
main contactor/breaker. Make sure that the
value is Delayed brake.
Sets the time after which the FSO module
activates the SBC function after it has activ-
ated the STO function.
0STO SBC delaySBC.12
In this manual, the SBC function is used to
control the main contactor/breaker. It is as-
sumed that you do not use a mechanical
brake. When the value is zero, the main
contactor/breaker and drive STO circuit are
opened at the same time. Make sure that
the value is 0.
Note: The default value after factory reset
is 3,600,000 ms. Always check this paramet-
er after factory reset.
Sets the time after which the motor has
stopped and the acknowledgment (and re-
start of the drive) is allowed after coast stop
in the STO, SSE and SS1 functions. Set
the value of this parameter to the estimated
time in which the motor coasts to a stop
from the maximum speed.
1000 msSBC time to zero

SBC.13
Emergency stop, stop category 0: This
parameter sets the time after which the STO
function is completed and the indication
lamp comes on. Adjust the value when ne-
cessary.
Emergency stop, stop category 1: This
parameter is used only when the motor
speed does not follow the ramp settings or
the time monitoring limit is exceeded and
the FSO module activates the STO and
SBC functions. Adjust the default value
when necessary.
Note: The default value after factory reset
is 3,600,000 ms. Always check this paramet-
er after factory reset.
When a safety encoder is used: This para-
meter is relevant only if an encoder or FSE-
31 module failure occurs. The FSO module
goes into the Fail-safe mode and activates
the STO and SBC functions (this also opens
the main contactor/breaker). For more in-
formation, see the FSO-21 module user’s
manual.
