The braking torque may increase because of the raising of braking resistor. The below table is
calculated at 100% of the braking torque, 10%, 50% and 80%of the braking usage ratio. The user
can select according to the actual working.
Refer to the operation instructions of braking units when using external units for right setting of
voltage degree. Otherwise normal operation of the VFD may be impacted.
