Note:
1. Select brake resistors according to the resistance and power data provided by our company.
2. The brake resistor may increase the brake torque of the VFD. The preceding table describes the
resistance and power for 100% brake torque, 10% brake usage, 50% brake usage, and 80%
brake usage. You can select the brake system based on the actual operation conditions.
3. When using an external brake unit, set the brake voltage class of the brake unit properly by
referring to the manual of the dynamic brake unit. If the voltage class is set incorrectly, the VFD
may not run properly.
Do not use brake resistors whose resistance is lower than the specified
minimum resistance. VFDs do not provide protection against overcurrent
caused by resistors with low resistance.
In scenarios where brake is frequently implemented, that is, the brake usage is
greater than 10%, you need to select a brake resistor with higher power as
required by the operation conditions according to the preceding table.
D.8.2 Brake resistor cable selection
Brake resistor cables need to be shielded cables.
D.8.3 Brake resistor installation
All resistors need to be installed in places with good cooling conditions.
The materials near the brake resistor or brake unit must be non-flammable.
The surface temperature of the resistor is high. Air flowing from the resistor is
