The preceding table describes external accessories. You need to specify the ones you
choose when purchasing accessories.
C.7 Braking resistors
C.7.1 Braking resistor selection
When the VFD driving a high-inertia load decelerates or needs to decelerate abruptly,
the motor runs in the power generation state and transmits the load-carrying energy to
the DC circuit of the VFD, causing the bus voltage of the VFD to rise. If the bus voltage
exceeds a specific value, the VFD reports an overvoltage fault. To prevent this from
happening, you need to configure brake components.

The design, installation, commissioning, and operation of the device
must be performed by trained and qualified professionals.

Follow all the "Warning" instructions during the operation.
Otherwise, major physical injuries or property loss may be caused.

Only qualified electricians are allowed to perform the wiring.
Otherwise, damage to the VFD or brake components may be caused.

Read the braking resistor instructions carefully before connecting
them to the VFD.

Connect braking resistors only to the terminals PB and (+). Do not
connect them to other terminals. Otherwise, damage to the brake
circuit and VFD and fire may be caused.

Connect the brake components to the VFD according to the wiring
diagram. If the wiring is not properly performed, damage to the VFD
or other devices may be caused.
