DC Braking After Stop Setting Details
Set the time to block the inverter output before DC braking. If the inertia
of the load is great, or if DC braking frequency (Ad.17) is set too high, a
fault trip may occur due to overcurrent conditions when the inverter
supplies DC voltage to the motor. Prevent overcurrent fault trips by
adjusting the output block time before DC braking.
Set the time duration for the DC voltage supply to the motor.
Set the amount of DC braking to apply. The parameter setting is based
on the rated current of the motor.
Set the frequency to start DC braking. When the frequency is reached,
the inverter starts deceleration. If the dwell frequency is set lower than
the DC braking frequency, dwell operation will not work and DC braking
will start instead.
• Note that the motor can overheat or be damaged if excessive amount of DC braking is
applied to the motor, or DC braking time is set too long.
• DC braking is configured based on the motor’s rated current. To prevent overheating or
damaging motors, do not set the current value higher than the inverter’s rated current.
