• S0.01 : The frequency where the DC braking starts.
It is valid only for deceleration.
• S0.02 : The level of output DC current during DC braking.
( in the percentage of rated inverter output current )
• S0.03 : Set the DC braking operation time before the motor is started.
• S0.04 : Set the DC braking operation time before the motor is stopped.
• In order to decrease the stopping time, increase DC braking current in
S0.02.
• To disable the DC braking, set DC braking time (S0.03 and S0.04) to 0.
