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.
