Note:
Select the resistor and power of the braking unit according to the data our company
provided.
The braking resistor may increase the braking torque of the VFD. The resistor power in the
above table is designed on 100% braking torque and 10% braking usage ratio. If the users
need more braking torque, the braking resistor can decrease properly and the power needs
to be magnified.
Never use a braking resistor with a resistance below the minimum value
specified for the particular drive. The drive and the internal chopper are
not able to handle the overcurrent caused by the low resistance.
Increase the power of the braking resistor properly in the frequent braking
situation (the frequency usage ratio is more than 10%).
C.7.2 Braking resistor installation
Braking resistor cables need to be shielded cables.
Install all resistors in a place where they will cool.
