3.5.6 Pr. 7, 8 Acceleration/deceleration time
These parameters are used to congure the motor acceleration/deceleration time.
Set larger values for slower acceleration/deceleration and smaller values for faster acceleration/deceleration.

As acceleration/deceleration time, set the
frequency change time from stop to Pr. 20.
(1) Acceleration time setting (Pr. 7, Pr. 20)
● Pr. 7 acceleration time congures the acceleration
time required to reach the Pr. 20 acceleration/
deceleration reference frequency from a stopped state.
(2) Deceleration time setting (Pr. 8, Pr. 20)
● Pr. 8 acceleration time congures the deceleration
time required to stop from the Pr. 20 acceleration/
deceleration reference frequency.
