Note:
1. The input EMI meets the requirement of C2 after installing input filters.
2. Above options are external, the customer should indicate when purchasing.
C.8 Braking system
C.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
the inverter.
Follow the instructions in “warning” during working; otherwise, physical injury or
death or serious property may occur.
Only qualified electricians are allowed to wire; otherwise, damage to the inverter
or braking options and parts may occur.
Read the instructions of braking resistors or units carefully before connecting
them with the inverter.
Do not connect the braking resistor with other terminals except for PB and (+).
Do not connect the braking unit with other terminals except for (+) and (-).
Otherwise, damage to the inverter or braking circuit or fire may occur.
Connect the braking resistor or braking unit with the inverter according to the
diagram. Incorrect wiring may cause damage to the inverter or other devices.
