Parameter Descriptions
SP-76 Accel/Decel Time 2 Type
Option:
[2] S-ramp Const
Time
NOTE
3 3
If [1] S-ramp Const Jerk 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

SP-84 Accel/Decel Ramp 3 Type
Option:
84
AF-650 GP Programming Guide
Function:
S-ramp based on the values set in E-10 Accel
Time 2 and E-11 Decel Time 2
Function:
(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:
(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:
(E-11 Decel Time 2) 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:
(E-11 Decel Time 2) 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 and
deceleration. A linear ramp will give
SP-84 Accel/Decel Ramp 3 Type
Option: Function:
constant acceleration during ramping. An S-
ramp will give non-linear acceleration,
compensating for jerk in the application.
[0] Linear
*
[1] S-ramp Const Accelerates with lowest possible jerk.
Jerk
[2] S-ramp Const S-ramp based on the values set in E-12 Accel
Time Time 3 and E-13 Decel Time 3
NOTE
If [1] S-ramp Const Jerk 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-87 Accel Time 3 S-ramp Ratio at Accel. Start
Range: Function:
50 % [1 - 99 %] Enter the proportion of the total accel time
*
(E-12 Accel Time 3) 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.
SP-88 Accel Time 3 S-ramp Ratio at Accel. End
Range: Function:
50 % [1 - 99 %] Enter the proportion of the total accel time
*
(E-12 Accel Time 3) 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.
SP-89 Decel Time 3 S-ramp Ratio at Decel. Start
Range: Function:
50 % [1 - 99 %] Enter the proportion of the total decel time
*
(E-13 Decel Time 3) 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.
SP-90 Decel Time 3 S-ramp Ratio at Decel. End
Range: Function:
50 % [1 - 99 %] Enter the proportion of the total decel time
*
(E-13 Decel Time 3) 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.
