Parameter settings 27
FSOGEN.42 Acknowledgement
button input
None
or eg,
DI X113:2 Sets the digital input for the acknowledgement signal when
parameter
STO.02 STO acknowledgement has value Manual .
None: No acknowledgement signal connected/required
(parameter STO.02 STO acknowledgement has value
Automatic).
DI X113:2:
The acknowledgement signal (reset circuit) is
connected to this digital input.
In the safety function described in this guide, you can use this
parameter to implement a manual reset in the FSO module
(see section
Resetting the safety function on page 19 ).
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.
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.
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 module after motor overtemperature situations.
Fault : You have to reset the drive/inverter module.
In the safety functions described in this guide, you can use
this indication as the motor overtemperature indication
message and to implement a manual reset. Adjust the default
value when necessary.
FSOGEN.62 STO indication
safety limit
Fault Sets the type of the event that the FSO module generates 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.
Check the default setting and adjust if necessary. If you select
Fault , you must reset the drive before you can restart it.
