Abstract:
An electronic module that dampens torsional oscillation of an object rotating in a horizontal plane in a system that includes a motor control. The electronic module includes a memory that is configured to store a mass-dependent value of the object or of rotating parts of the system, a housing, and a processor that is positioned within the housing. The processor is configured to receive a mass-dependent value of the object, store the mass-dependent value of the object in the memory, calculate a torsional oscillation dampening signal using an algorithm that is based at least in part on the mass-dependent value of the object or of the rotating parts of the system, and transmit the torsional oscillation dampening signal to the motor control thereby dampening torsional oscillation of the object rotating in the horizontal plane.
