request
FSOGEN.62 STO indication safety
limit
Example value Description
0.0 rpm Sets the general zero speed limit for safety functions
when a safety encoder is in use.
STO function: The drive STO function is active (cannot
be reset) until the motor speed is less than or equal to
this value.
SS1 function: The FSO module activates the drive STO
function when the drive has decelerated the motor
speed to less than this value. Adjust the default value
according to application requirements.
ACS880-07/17/37 and ACS880-17LC/37LC drives with
the option +Q978: Also the main contactor/breaker is
opened.
Note: This parameter is used only with FSO-21 and
when a safety encoder is used in the application.
Warning Sets the type of the event that the FSO module gener-
ates and sends to the drive after external requests that
end to a successful activation of the drive STO function
(STO, SSE or SS1).
None, Warning, Event: You do not have to reset the
drive/inverter unit.
Fault: You have to reset the drive/inverter unit.
In the safety functions described in this manual, you
can use this indication as the motor overtemperature
indication message and to implement a manual reset.
Adjust the default value when necessary.
Fault Sets the type of the event that the FSO module gener-
ates and sends to the drive for limit hits during ramp
and time monitoring of safety ramps SAR0 and SAR1.
STO function: The value has no effect.
SS1 function: When the motor speed does not follow
the stop ramp or the time limit is exceeded, the FSO
module activates the STO function and generates this
user-defined indication. Adjust the default setting if ne-
cessary. If you select Fault, you must reset the drive
before you can restart it.
