DC Braking After Stop Setting Details

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.
Ad.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.
• 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.
4.17.3 Free Run Stop
When the Operation command is off, the inverter output turns off, and the load stops due to
residual inertia.
