There are parameters that you must always set and parameters that are related to certain
safety functions only. These tables list all the parameters that you must check and set for
the option +Q978. The example values apply only to the option +Q978.
￭ General parameters
These parameters are common to all safety functions.
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.
DO X114:7Stop completed out-
put
FSOGEN.11
For the option +Q978, 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 delivery.
Sets the nominal motor speed. Adjust the
default value to meet the ratings of the mo-
tor in use.
1500 rpmMotor nominal speedFSOGEN.21
Sets the nominal motor frequency. Adjust
the default value to meet the ratings of the
motor in use.
50 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 generates the acknow-
ledgement signal automatically after the
power-up.
Manual: The FSO module reads the extern-
al acknowledgement signal through the di-
gital input defined by parameter FSO-
GEN.42.
Make sure that the value is Automatic.
Sets the digital input for the acknowledg-
ment signal when parameter FSOGEN.41
Power-up acknowledgement or STO.02
STO acknowledgement has value Manual.
DI X114:2Acknowledgement
button input
FSOGEN.42
For the option +Q978, ABB has configured
the emergency stop reset button to this di-
gital input at the factory. Make sure that this
value corresponds to the actual wiring. See
the circuit diagrams of the delivery.
Sets the general zero speed limit for safety
functions when no safety encoder is in use.
90 rpmZero speed without
encoder
FSOGEN.51
Emergency stop, stop category 0: This
value has no effect in the operation.
Emergency stop, stop category 1: The FSO
module activates the drive STO function
and opens the main contactor/breaker when
the drive has decelerated the motor speed
below this value. Adjust the default value
when necessary.
