1. The input EMI meet the requirement of C2 after adding input filters.
2. Above options are external, the customer should indicate when purchasing.
C.7 Braking components
C.7.1 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 braking resistors or
units 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 (-).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.
Goodrive20 series inverters have internal braking units.
