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.

~Actual
acceleration
time
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 tied-weakening area.)
