SP-72 Accel Time 1 S-ramp Ratio at Accel. End
Range:
50 %* [1 - 99. %]
SP-73 Decel Time 1 S-ramp Ratio at Decel. Start
3 Range:
50 %* [1 - 99. %]
SP-74 Decel Time 1 S-ramp Ratio at Decel. End
Range:
50 %* [1 - 99. %]
SP-76 Accel/Decel Time 2 Type
Option:
[0] * Linear
[1] S-ramp Const Jerk
[2] S-ramp Const Time
NB!
If S-ramp [1] is selected and the reference during ramping is changed the ramp time may be prolonged in order to realize 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.
SP-79 Accel Time 2 S-ramp Ratio at Accel. Start
Range:
50 %* [1 - 99. %]
SP-80 Accel Time 2 S-ramp Ratio at Accel. End
Range:
50 %* [1 - 99. %]
SP-81 Decel Time 2 S-ramp Ratio at Decel. Start
Range:
50 %* [1 - 99. %]

Function:
Enter the proportion of the total accel time (par. 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 (par. F-08 Decel Time 1) where the deceleration torque in-
creases. 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 (par. F-08 Decel Time 1) where the deceleration torque de-
creases. 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 will give
constant acceleration during ramping. An S-ramp will give non-linear acceleration, compensating for jerk
in the application.
Acceleration with lowest possible jerk
S-ramp based on the values set in par. E-10 Accel Time 2 and par. E-11 Decel Time 2
Function:
Enter the proportion of the total accel time (par. E-10 Accel Time 2) in which the acceleration 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 accel time (par. E-10 Accel Time 2) 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 (par. E-11 Decel Time 2) where the deceleration torque in-
creases The larger the percentage value, the greater the jerk compensation achieved, and thus the lower
the torque jerks in the application.
