General Parameters - ABB ACS880-07 User Manual

34 Parameter settings
Note: The FSO module has a factory reset button. The factory reset button clears the
configuration and sets the parameters to the factory default values. These values are not
the same as the pre-set values in an FSO module that was ordered as an option (with a
plus code). You cannot restart the drive with the factory default values. If you do a factory
reset of the FSO module, you must reconfigure the FSO module and set all applicable
parameters. For more information on the factory reset, see the FSO module user's manual.
When using SS1, SLS or SMS safety functions: The FSO module activates the STO function
if the motor speed hits a ramp monitoring limit during the deceleration ramp. The FSO
module activates the SSE function if the motor speed hits a trip limit during SLS or SMS
monitoring. Thus, you must also configure the STO and SSE functions.
Follow the configuration steps described in the FSO module user's manual, chapter
Configuration.
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
option +Q979. The example values are applicable only to option +Q979.

Example value Description
DO X114:7 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.
For option +Q979, ABB has configured the
emergency stop indication lamp to this digit-
al output at the factory. Make sure that this
value corresponds to the actual wiring. See
the circuit diagrams of the delivery.
1500 rpm Sets the nominal motor speed. Must be
equal to the value on the motor rating plate.
50 Hz Sets the nominal motor frequency. Must be
equal to the value on the motor rating plate.
Automatic Sets the power-up acknowledgement
method of the FSO module.
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 external
acknowledgement signal through the digital
input defined by parameter FSOGEN.42.
Make sure that the value is Automatic.
DI X114:2 Sets the digital input for the acknowledg-
ment signal when parameter FSOGEN.41
Power-up acknowledgement or STO.02 STO
acknowledgement is set to Manual.
For option +Q979, ABB has configured the
emergency stop reset button to this digital
input at the factory. Make sure that this
value corresponds to the actual wiring. See
the circuit diagrams of the delivery.
