￭ General parameters
These parameters are common to all safety functions in the FSO module.
DescriptionExample valueNameIndex
Sets the digital output that indicates the completion of
any stop function. Active when the FSO module has
completed the STO, SSE or SS1 function.
NoneStop completed out-
put
FSOGEN.11
ACS880-07/17/37 and ACS880-17LC/37LC drives with
the option +Q978 or +Q979: ABB has configured the
emergency stop indication lamp to this digital output at
the factory. Make sure that this value corresponds to
the actual wiring. See the circuit diagrams of the deliv-
ery. Do not change this setting.
Sets the nominal motor speed. Adjust the default value
to meet the ratings of the motor in use.
1500.0 rpmMotor nominal speedFSOGEN.21
Sets the nominal motor frequency. Adjust the default
value to meet the ratings of the motor in use.
50.00 HzMotor nominal fre-
quency
FSOGEN.22
Sets the power-up acknowledgement method of the
FSO module.
AutomaticPower-up acknow-
ledgement
FSOGEN.41
Automatic: You do not need to push a reset button after
switching on the FSO module. The FSO module gener-
ates the acknowledgement signal automatically after
the power-up.
Manual: The FSO module reads the external acknow-
ledgement signal through the digital input defined by
parameter FSOGEN.42.
Make sure that the value is Automatic.
Sets the digital input for the acknowledgement signal
when parameter STO.02 has value Manual.
NoneAcknowledgement
button input
FSOGEN.42
None: In the safety functions described in this manual,
parameter STO.02 has value Automatic and this para-
meter has value None (no acknowledgement signal
connected).
In the safety functions described in this manual, you
can use this parameter to implement manual reset in
the FSO module. Set the digital input which the reset
circuit is connected to with this parameter.
ACS880-07/17/37 and ACS880-17LC/37LC drives with
the option +Q978 or +Q979: The value of this parameter
is DI X113:2. A reset circuit is connected to the FSO
module and the user must reset the safety function with
the emergency stop reset button also when motor
overtemperature is reached. Do not change this setting.
Sets the general zero speed limit for safety functions
when no safety encoder is in use.
90.0 rpmZero speed without
encoder
FSOGEN.51
STO function: The value has no effect.
SS1 function: The FSO module activates the drive STO
function when the drive has decelerated the motor
speed below this value. Adjust the default value accord-
ing to application requirements.
ACS880-07/17/37 and ACS880-17LC/37LC drives with
the option +Q978: Also the main contactor/breaker is
opened.
