Set a delay time after the inverter output turns off and before applying DC
braking. If the inertia of the load is high, or if DC braking frequency (ADV-17) is
set too high, a fault may occur due to overcurrent conditions when the inverter
supplies DC voltage to the motor. To prevent overcurrent fault, adjust the delay
time before DC braking.
Set the time duration for the DC voltage supplied to the motor.
Set the amount of DC braking current to apply. The parameter setting is based on
the rated current of the motor. The maximum value of the DC Brake current is
limited to the inverter rated current. Maximum DC Brake Level = Inverter
rated current / Rated current of motor X 100%.
Set the frequency to start DC braking. When the inverter output frequency is
reached, the inverter starts DC Braking. If the dwell frequency is set lower than
the DC braking frequency, dwell operation will not work and DC braking will
start instead.
5.4.3.3 Free Run Stop
When the run command is removed, the inverter output turns off and the motor/load coasts to a stop.
Note: With high inertia loads the motor will continue to rotate. The inverter does not control the
motor during Free-Run.
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.
