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.
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.
The start after the protection or free stop may be enabled by default according to the F04.00 184 eed current Leave-fa Function Function code Parameter description Unit ctory Attribute code name value F04.24 Flux braking gain 100-150 (100: no flux braking) 100 〇 Function Function code Default Parameter description Unit Attribute code name setting F04.26 Start mode after protection/free stop 0: start according to F04.00 setting mode 1: start of speed tracking 0 〇
