Description Example value Name Index
Sets the type of the event that the FSO module gener-
ates and sends to the drive for limit hits during ramp
and time monitoring of safety ramps SAR0 and SAR1. Fault STO indication safety
limit FSOGEN.62
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. Adjust the default setting if ne-
cessary. If you select
Fault , you must reset the drive
before you can restart it.
￭ Parameters for the STO function
These parameters are related to the STO function of the FSO module. With stop category
0, the FSO module activates the STO function in overtemperature situations. Also, the FSO
module can activate the STO function in fault situations.
Description Example value Name Index
Sets the acknowledgement method used in the STO,
SSE and SS1 functions. Automatic or
Manual STO acknowledge-
ment STO.02
Automatic : The FSO module resets the STO function
automatically after the STO request is removed.
Manual : The FSO module reads the external acknow-
ledgement signal through the digital input defined by
parameter
FSOGEN.42 . In the safety functions de-
scribed in this manual, you can use this setting to im-
plement a manual reset for the motor temperature
protection function in the FSO module.
Sets the digital input that is connected to the primary
input of the STO function. STO: DI X113:1
& X114:1 STO input A STO.11
If you set this parameter to DI X113:1 & X114:1 , set
parameter SS1.11 to None .
SS1: None
Sets the digital input that is connected to the secondary
input of the STO function. None STO input B STO.12
Sets the time after which the drive can restart when the
FSO module has activated the STO function and
opened the drive STO circuit. With this parameter, you
can let the drive restart before the motor has stopped
(fly-start). This parameter is applicable only if the STO
function is requested from STO input A (
STO.11 ) or
STO input B ( STO.12 ).
2000 ms Restart delay after
STO STO.13
STO function: Adjust the value when necessary. If you
do not want to use the fly-start feature, set this paramet-
er to the same value as parameter
STO.14 .
SS1 function: This value has no effect.
