Start Mode Setting
Select the start mode to use when a start command is applied to the inverter.
Acceleration Start
Acceleration start is the general acceleration mode used when starting a motor from a stopped
condition. If there are no other settings applied, the motor accelerates to the frequency reference
when the start command is applied.

Start After DC Braking
This start mode supplies a DC voltage for a set amount of time to provide DC braking before an
inverter starts to accelerate a motor. If the motor is rotating before a start command due to its
inertia, DC braking will stop the motor, allowing the motor to accelerate from a stopped condition.
DC braking can also be used with a mechanical brake connected to a motor shaft if a constant
torque is required after the the mechanical brake is released.

13 DC Injection Level DC Inj Level 50 0–200 %
The amount of DC braking required [Ad.13 percent] is based on the motor’s rated current. Do not use
DC braking levels that can cause current draw to exceed the rated current of the inverter. If the DC
braking level is too high or brake time is too long, the motor may overheat or be damaged.
