[1] S-ramp
Const Jerk
[2] S-ramp
Const Time
NOTICE
If [1] S-ramp Const Jerk is selected and the reference
during ramping is changed, the ramp time may be
prolonged to realise a jerk-free movement, which may
result in a longer start or stop time.
Additional adjustment of the S-ramp ratios or switching
initiators may be necessary.

Function:
compensation achieved, and thus the lower
the torque jerks occurring in the application.
Function:
Enter the proportion of the total accel time
(parameter F-07 Accel Time 1) in which the
acceleration torque decreases. The larger the
percentage value, the greater the jerk
compensation achieved, and thus the lower
the torque jerks in the application.
Function:
Enter the proportion of the total decel time
(parameter F-08 Decel Time 1) 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.
Function:
Enter the proportion of the total decel time
(parameter F-08 Decel Time 1) 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.
Function:
Select the ramp type, depending on
requirements for acceleration/deceleration. A
linear ramp gives constant acceleration during
ramping. An S-ramp gives non-linear
acceleration, compensating for jerk in the
application.
Acceleration with lowest possible jerk.
S-ramp based on the values set in
parameter E-10 Accel Time 2 and
parameter E-11 Decel Time 2.

Function:

deceleration torque decreases. The larger the
percentage value, the greater the jerk
compensation achieved, and thus the lower
the torque jerks in the application.
Function:
Select the ramp type, depending on
requirements for acceleration and deceleration.
A linear ramp gives constant acceleration
during ramping. An S-ramp gives non-linear
acceleration, compensating for jerk in the
application.
Accelerates with lowest possible jerk.
S-ramp based on the values set in
parameter E-12 Accel Time 3 and
parameter E-13 Decel Time 3.
