Linear
acceleration/
deceleration
Acceleration is made to the set frequency linearly.
(Factory setting)
1
S-shaped
acceleration/
deceleration A (*)
For machine tool spindle applications, etc.
Used when acceleration/deceleration must be made in a short
time to a high-speed region of not lower than the base frequency.
Acceleration/deceleration is made in a pattern where fb (base
frequency) acts as the inflection point of an S shape, and you can
set the acceleration/deceleration time which matches the motor
torque reduction in the constant-output operation region of not
lower than the base frequency.
2
S-shaped
acceleration/
deceleration B
For conveyor and other load collapse prevention applications, etc.
Since acceleration/deceleration is always made in an S shape
from f2 (current frequency) to f1 (target frequency), this function
eases shock produced at acceleration/deceleration and is
effective for load collapse prevention, etc.
CAUTION
* As the acceleration/deceleration time, set the time taken to reach the Pr. 3 "base
frequency" value, not the Pr. 20 "acceleration/deceleration reference frequency"
value. For details, refer to page 59.
