Parameter Descriptions
42-48 S-ramp Ratio at Decel. Start
Range: Function:
50 % [1 - 99 %] The proportion of the total ramp
*
down time (parameter 42-42 Delay
Time) where the deceleration
torque increases. The larger the
percentage value, the greater the
jerk compensation achieved, and
thus the lower the torque jerks in
the application.
42-49 S-ramp Ratio at Decel. End
Range: Function:
50 % [1 - 99 %] The proportion of the total
*
rampdown time
(parameter 42-42 Delay Time) where
the deceleration torque decreases.
The larger the percentage value,
the greater the jerk compensation
achieved, and thus the lower the
torque jerks in the application.
42-50 Cut Off Speed
Range: Function:
270 RPM [120 - 10000 Speed at which the fail-safe
*
RPM] reaction gets activated. This should
be the value of parameter 42-51
Speed Limit plus a tolerance.
42-51 Speed Limit
Range: Function:
150 RPM [0 - 9999 Maximum speed allowed when the
*
RPM] SLS function is active.
42-52 Fail Safe Reaction
Option: Function:
[0] STO STO is activated when the speed
*
exceeds the limit. This is applicable
only for SLS.
[1] SS1-a SS1-a is activated when the speed
exceeds the limit. This is applicable
only for SLS.
[2] SS1-b SS1-b is activated when the speed
exceeds the limit. This is applicable
only for SLS.
42-53 Start Ramp
Option: Function:
[0] No If the speed at activation of SLS is
*
higher than the speed limit, it
activates a STO.
[1] Yes If the speed at activation of SLS is
higher than the speed limit, it
ramps down to the speed limit
