The manual says: Check resistance brake resistor value is greater than minimum allowed.

This alarm is triggered by brake resistor overcurrent. The cause for the overcurrent can be improper resistor sizing, shorted or melted resistor wiring, or a failed resistor. You'll have to do some research in the brake resistor circuit to clear this fault permanently.
