P1-16 Stop braking DC current 0%
～
100% 0%
☆
This parameter is used to set the percentage of DC braking current, and the rated current of
the inverter is 100%. The larger the braking current is, the more obvious the braking effect is,
but when the braking current is too large, the braking time P1-17 should not be set too large.

P1-17 Stop braking DC current 0% ～ 100% 0%
☆
This parameter is used to set the DC braking holding time. When it is 0, there is no DC braki-
ng process.

P1-21 Demagnetization time 0.01s ～ 3.00s 0.50s
★
This parameter is used to set the waiting time of the inverter from coasting to restart, so as to
reduce the influence of motor residual magnetism on startup.

★
This parameter is used to set the method to prevent the shutdown due to the bus voltage
undervoltage caused by the grid voltage drop, and is often used in fan and other occasions.
0: Invalid, it will still run at the given frequency when the grid voltage is momentarily cut off.
At this time, an undervoltage fault may occur and the machine will shut down;
1: Automatically adjust the deceleration rate, and automatically adjust the deceleration rate
when the grid voltage is momentarily cut off to keep the inverter running. After the grid volta-
ge recovers, it will automatically accelerate to the target frequency. If the power grid is out of
power for a long time, there will still be an undervoltage fault and shutdown;
2: Decelerate to stop. In case of instantaneous power failure or sudden voltage drop, the
inverter will decelerate and stop according to P1-24. If you need to start again after stopping,
you need to give the start signal again.
