Acc/Dec pattern adjustment (HIGH)
An acc/dec pattern that matches the application can be selected.
SCu I set to 0 (Linear acc/dec) This is a general acceleration/deceleration pattern, and is used under
most circumstances.
SCu I set to I (Self-adjusting function) An acceleration/deceleration time that matches the load conditions
is automatically set.
Self-adjusting function
This function cannot be used when the frequency reference constantly fluctuates or when the load
changes suddenly. The |ncc j jdEC | parameters will be automatically changed, but when the control
power is turned OFF, the settings will return to their original values.

SCuS I for^ andpECE.
SCu I set to 3 (S-Pattern #1)
SCu I set to 3 (S-Pattern #2)
This pattern is used when accelerating/decelerating to a high speed
area (exceeding 60Hz) is required in a short time. This pattern is
suitable for conveyers, etc.
This pattern gradually accelerates in the field-weakening area where
the motor’s acceleration torque is small. This pattern is suitable
for high-speed spindles.

Output
Note that actual acceleration/deceleration times of the S-pattern will be longer than the linear times by the values
of *1 and *2.
The curve will depend on the (max. voltage frequency/max. frequency), and the inclination will taper off as the
(max. voltage frequency/max frequency) decrease, and the actual acceleration time will increase. (The rate of
acceleration will decrease in the field-weakening area.)
