Description Example value Name Index
Sets the monitoring delay after which the FSO module
activates the drive STO and SBC at the latest, if the
motor speed has not gone below the zero speed limit
(parameter
FSOGEN.51 or FSOGEN.52 ) yet.
20000 ms SS1-t delay for STO SS1.14
Time monitoring: This value sets the security delay that
the FSO module monitors. Adjust the default value
when necessary.
Ramp monitoring: This value has no effect in the oper-
ation.
SAR1 ramp settings
Sets the target time for the stop ramp SAR1 that is used
in the SS1 and function. Adjust the default value when
necessary. 2000 ms SAR1 ramp time to
zero 200.112
The target time is the time in which the drive deceler-
ates the motor from the speed defined by parameter
200.202 to zero.
Note: With value 0 ms , the drive uses the emergency
stop ramp set by drive parameter 23.23 (see section
SS1 ramp parameters in the drive/inverter
unit (page 33)
). Also in this case, the FSO module only
monitors the actual ramp (ramp monitoring or time
monitoring).
Sets a speed value that the FSO module uses as a
reference point in ramp parameter calculations (see
SAR1 ramp parameters
200.112 , SARx.21 , SARx.22
and SARx.02 .). Adjust the default value when neces-
sary.
1500 rpm SAR speed scaling 200.202
Sets the initial allowed range for the SAR0/SAR1 ramp.
This parameter moves the location of the maximum
monitoring ramp forward on the time axis, when monit-
oring is started. The slope of the ramp stays the same
as defined with parameters
200.202 and SARx.22 . For
more information, see the FSO module user’s manual.
100 ms SAR initial allowed
range SARx.02
Time monitoring: This value has no effect in the opera-
tion.
Ramp monitoring: Adjust the default value when neces-
sary.
Sets the minimum ramp time for the SAR1 ramp monit-
oring. 1000 ms SAR1 min ramp time
to zero SARx.21
Time monitoring: This value has no effect in the opera-
tion.
Ramp monitoring: Sets the minimum stop ramp time
for the emergency stop. Adjust the default value when
necessary.
Note: With value 0 ms , the minimum ramp is not mon-
itored.
Sets the maximum ramp time for the SAR1 ramp
monitoring. 3000 ms SAR1 max ramp time
to zero SARx.22
Time monitoring: This value has no effect in the opera-
tion.
Ramp monitoring: Sets the maximum stop ramp time
for the emergency stop. Adjust the default value when
necessary.
