Example value Description
20000 ms 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
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.
2000 ms Sets the target time for the stop ramp SAR1 that is used
in the SS1 and function. Adjust the default value when
necessary.
The target time is the time in which the drive deceler-
ates the motor from the speed defined by parameter
200.202
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
monitors the actual ramp (ramp monitoring or time
monitoring).
1500 rpm 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,
and SARx.02.). Adjust the default value when neces-
sary.
100 ms 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
more information, see the FSO module user's manual.
Time monitoring: This value has no effect in the opera-
tion.
Ramp monitoring: Adjust the default value when neces-
sary.
1000 ms Sets the minimum ramp time for the SAR1 ramp monit-
oring.
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.
3000 ms Sets the maximum ramp time for the SAR1 ramp
monitoring.
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.
