Acceleration and Deceleration Characteristics
This section explains the acceleration and deceleration characteristics of the Drive.
‹ Setting Acceleration and Deceleration Times
Acceleration time indicates the time taken for the output frequency to climb from 0% to 100%. Deceleration
time indicates the time taken for the output frequency to reduce to 0%. The factory setting of the acceleration
time is C1-01, and the factory setting of the deceleration time is C1-02.
