Brake resistor

What does 42 mean?

Problems have been detected with the brake resistor, which is used to dissipate regenerative energy during deceleration. This could indicate the resistor is faulty, incorrectly sized, or the deceleration time is too short for the current load. A malfunctioning brake resistor can lead to overvoltage faults.
