3-45 Ramp 1 S-ramp Ratio at Accel. Start
Range:
Function:
50 %
*
[Application
dependant]
Enter the proportion of the total ramp-
up time (
3-41 Ramp 1 Ramp up Time
) in
which the acceleration torque
increases. The larger the percentage
value, the greater the jerk compen-
sation achieved, and thus the lower the
torque jerks occurring in the
application.
3-46 Ramp 1 S-ramp Ratio at Accel. End
Range:
Function:
50 %
*
[Application
dependant]
Enter the proportion of the total ramp-
up time (
3-41 Ramp 1 Ramp up Time
) in
which the acceleration torque
decreases. The larger the percentage
value, the greater the jerk compen-
sation achieved, and thus the lower the
torque jerks in the application.
3-47 Ramp 1 S-ramp Ratio at Decel. Start
Range:
Function:
50 %
*
[Application
dependant]
Enter the proportion of the total ramp-
down time (
3-42 Ramp 1 Ramp Down
Time
) where the deceleration torque
increases. The larger the percentage
value, the greater the jerk compen-
sation achieved, and thus the lower the
torque jerks in the application.
3-48 Ramp 1 S-ramp Ratio at Decel. End
Range:
Function:
50 %

Enter the proportion of the total ramp-
down time (
3-42 Ramp 1 Ramp Down
Time
) where the deceleration torque
decreases. The larger the percentage
value, the greater the jerk compen-
sation achieved, and thus the lower the
torque jerks in the application.
