Acceleration And Deceleration Characteristics; Setting Acceleration And Deceleration Times - YASKAWA FSDrive-MV1S Instructions Manual

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.
