Acceleration and Deceleration Characteristics
This section explains the acceleration and deceleration characteristics of the Inverter.
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.
