摘要： A system and method for determining the load present in a material handling system is disclosed. A commissioning routine executing on a motor drive controls operation of a hoisting motor with a known load present. The commissioning routine stores values of current provided to the motor or torque generated by the motor at various operating speeds in memory on the motor drive. During subsequent runs of the motor drive, the value of the current/torque is monitored as a function of the speed of the motor and compared to the stored values. The resulting value of the load may be monitored and action taken if the value of the load exceeds the rated capacity of the material handling system. Optionally, the measured load may be displayed to an operator.

摘要： A variable speed power converter controls the speed of a load in a material handling system as a function of the torque required to move the load. While the power converter is running, the torque being produced in the motor is determined. The power converter then determines the maximum rotational speed of the motor as a function of the torque currently being produced and of the torque-speed curve of the motor. The power converter then commands the motor to rotate at this maximum rotational speed. The power converter periodically monitors the torque being produced and adjusts the maximum rotational speed of the motor throughout the run.

摘要： A system and method for determining the holding torque of a brake in a material handling system is disclosed. The material handling system may include a bridge, a trolley, and a hoist, each driven along a different axis by a motor. A brake is operatively coupled to the motor to prevent unwanted motion of the motor. A motor controller is coupled to each motor which controls operation of the motor and its corresponding brake. The motor controller generates a torque command to the motor while keeping the brake set. The initial torque command is less than the holding torque of the brake. The torque command is incremented until motion is detected on the motor. The torque value when motion is detected is stored in the motor controller and displayed to an operator.
