Fig. 7-17 DC Braking Process for Start Fig. 7-18 DC Braking Process for Stop
In the presence of heavy loads, the motor cannot be stopped completely through
normal deceleration due to inertia. You can extend the duration of DC braking for
stop or increase the current of DC braking for stop to stop the motor from rotating.

Flux braking gain 100-150 (100: no flux braking)
100
〇
When the magnetic flux braking is valid (F04.24>100), the motor can be quickly slowed
down by increasing its magnetic flux, and the electric energy can be converted into thermal
energy during motor braking.
Flux braking may lead to quick deceleration, but the output current may be high. The flux
braking intensity (F04.24) can be set restriction and protection to avoid damage to the motor. If
flux braking is not applied, the deceleration time will be extended but the output current will be
low.
