4.15.2 DC Braking After Stop
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 Ad.17, the inverter supplies DC voltage to the
motor and stops it.

Description
Ad.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 (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.
Ad.15 Dc-Brake
Time
Set the time duration for the DC voltage supply to the motor.
Ad.16 Dc-Brake
Level
Set the amount of DC braking to apply. The parameter setting is
based on the rated current of the motor. The maximum value of the
DC braking rate is limited as an inverter rated current.
Maximum Value of Dc-Brake Level = Rated Current of
Inverter/Rated Current of Motor x 100%
