Parameter settings 47
FSOGEN.41 Power-up
acknowledgement
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
acknowledgement 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.
FSOGEN.42 Acknowledgement
button input
None Sets the digital input for the acknowledgement signal when
parameter STO.02 STO acknowledgement has value Manual.
None: In the safety functions described in this manual,
parameter STO.02 STO acknowledgement has value
Automatic and this parameter 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
(see section Resetting the ATEX-certified motor thermal
protection function on page 19 or 34). Set the digital input
which the reset circuit is connected to with this parameter.
ACS880-07/17/37 drives with the option +Q978 or +Q979:
The value of this parameter is DI X113:2. A reset circuit is
connect 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.
FSOGEN.51 Zero speed without
encoder
90 rpm Sets the general zero speed limit for safety functions when no
safety encoder is in use.
STO function
: The value has no effect.
SS1 function
: The FSO module activates drive STO function
when the drive has decelerated the motor speed below this
value. Adjust the default value when necessary.
ACS880-07/17/37 drives with the option +Q978
: Also the main
contactor/breaker is opened.
FSOGEN.52 Zero speed with
encoder
0 rpm Sets the general zero speed limit for safety functions when a
safety encoder is in use.
STO function
: The value has no effect.
SS1 function: The FSO module activates drive STO function
when the drive has decelerated the motor speed below this
value. Adjust the default value when necessary.
ACS880-07/17/37 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.
FSOGEN.61 STO indication ext
request
Warning Sets the type of the event that the FSO module generates 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.
