choose when purchasing accessories.
D.8 Braking system
D.8.1 Braking component 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 braking 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 braking components may be caused.
 Read the braking resistor or unit instructions carefully before connecting them to
the VFD.
