Enter the proportion of the total ramp-up time (parameter 3-41 Ramp 1 Ramp Up 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.
Parameter 3-84 Quick Stop S-ramp at Decel. End

3-84 Quick Stop S-ramp at Decel. End
Parameter type: Range, 1 - 99%
Change during operation: True
Enter the proportion of the total ramp-down time (parameter 3-42 Ramp 1 Ramp Down Time) where the deceleration torque decrea-
ses. The larger the percentage value, the greater the jerk compensation achieved, and thus the lower the torque jerks in the applica-
tion.
Parameter 3-89 Ramp Lowpass Filter Time

3-89 Ramp Lowpass Filter Time
Parameter type: Range, 1 - 2000 ms
Change during operation: True
Use this parameter to set how smoothly the speed changes.
5.4.10 3-9* Digital Pot.Meter
The digital potentiometer enables increase or decrease of the actual reference by adjusting the setup of the digital inputs using the
functions increase, decrease, or clear. To activate the function, set at least 1 digital input to increase or decrease.
