Select the stopping method suitable for the application.

Deceleration to a Stop

Example when acceleration/deceleration time 1 is selected

* Changing the Frequency Reference while Running

Upon termination of a FWD (REV) RUN command, the motor deceler-

ates at the deceleration rate determined by the time set in Deceleration

Time 1 (n17) and DC injection braking is applied immediately before

stopping. DC injection braking is also applied when the motor deceler-

ates because the frequency reference is set lower than the Min. Output

Frequency (n14) when the FWD (REV) RUN command is ON. If the

deceleration time is short or the load inertia is large, an overvoltage

(OV) fault may occur at deceleration. In this case, increase the decelera-

tion time.
