The inverter decelerates from the normal running velocity to the stopping frequency P12.01, and
then decelerates to zero according to the set deceleration time after the stopping frequency holding
time P12.02, which will be beneficial for smooth stopping.

P12.03 - P12.05 will be valid only when "Deceleration + DC braking (P12.00=2)" is selected for the
stopping mode.
The stopping DC braking current (P12.03) is set as a percentage relative to the rated current of the
inverter. If the set DC braking current is greater than 100% of the rated motor current, the current
injected will be 100% of the rated motor current. Under heavy load: 0.0 - 100.0%; under light load:
0.0 - 90.0%.
The starting DC braking time (P12.04) refers to the injection time. When P12.04=0, there is no DC
braking process.
When P12.00=2, P12.03 can be set as the braking starting frequency for fast braking.
P12.03 is used to set the size of the DC braking current, and this value is a percentage relative to
rated current of the inverter. The value under varying torque load: 0.0 to 90.0%.
P12.04 is used to set the action time of DC braking.
