D.8 Brake system

D.8.1 Select the brake components
It is appropriate to use brake resistor or brake 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 brake 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 brake
options and part may occur. Read carefully the instructions of brake resistors or
units before connecting them with the inverter.
 Do not connect the brake resistor with other terminals except for PB and (-). Do
not connect the brake unit with other terminals except for (+) and (-). Damage to
