4.17.2 Stop After DC Braking
When the operation frequency reaches the set value during deceleration (DC braking frequency)
the inverter stops the motor by supplying DC power to the motor. With a stop command input,
the inverter begins decelerating the motor. When the frequency reaches the DC braking
frequency set at ADV-17, the inverter supplies DC voltage to the motor and stops it.

DC Braking After Stop Setting Details
Code Description
ADV-14 DC-Block
Time
Set the time to block the inverter output before DC braking. If the inertia of the
load is great, or if DC braking frequency (ADV-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.
ADV-15 DC-Brake
Time
Set the time duration for the DC voltage supply to the motor.
ADV-16 DC-Brake
Level Set the amount of DC braking to apply. The parameter setting is based on the
rated current of the motor.
ADV-17 DC-Brake
Freq
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.
