Abstract
The invention relates to an arrangement and method for detecting failure of an electromechanical brake in an electromechanical drive system. The arrangement being characterized in that it comprises a control unit arranged to: send a drive torque signal to an electrical traction motor in the electromechanical drive system while the electromechanical brake is in an active braking position, detect if said applied drive torque causes a driving movement in the electrical traction motor, and indicate a mechanical failure of the electromechanical brake in case a driving movement in the electrical traction motor is caused by said applied drive torque. The invention further relates to a method for detecting failure of an electromechanical brake in an electromechanical drive system, and an industrial truck comprising the arrangement.
