Parameter Description
3-45 Ramp 1 S-ramp Ratio at Accel. Start
Range: Function:
50 % [Application Enter the proportion of the total ramp-
*
dependant] 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 Enter the proportion of the total ramp-
*
dependant] 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 Enter the proportion of the total ramp-
*
dependant] 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 % [Application Enter the proportion of the total ramp-
*
dependant] 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.

dependant] up time (3-51 Ramp 2 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 in the application.

Function:
[Application Enter the proportion of the total ramp-

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.
