D.8 Braking system
D.8.1 Select the braking components
It is appropriate to use braking resistor or braking unit when the motor brakes sharply or the
motor is driven by a high inertia load. The motor will become a generator if its actual rotating
speed is higher than the corresponding speed of the reference frequency. As a result, the
inertial energy of the motor and load return to the inverter to charge the capacitors in the
main DC circuit. When the voltage increases to the limit, damage may occur to the inverter. It
is necessary to apply braking unit/resistor to avoid this accident happens.
 Only qualified electricians are allowed to design, install, commission and
operate on the inverter.
 Follow the instructions in "warning" during working. Physical injury or death
or serious property may occur.
 Only qualified electricians are allowed to wire. Damage to the inverter or
braking options and part may occur. Read carefully the instructions of
