Brake component selection

D.8.1
When an inverter 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 inverter, causing the bus voltage of the inverter to rise. If the bus voltage exceeds a
specific value, the inverter 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. damage to
the inverter or brake components may be caused.
Read the brake resistor or unit instructions carefully before connecting them to
the inverter.
Connect brake resistors only to the terminals PB and (+), and brake units
only to the terminals (+) and (-). Do not connect them to other terminals.
Otherwise, damage to the brake circuit and inverter and fire may be caused.
Connect the brake components to the inverter according to the wiring diagram.
If the wiring is not properly performed, damage to the inverter or other devices
may be caused.
