Title:
METHOD FOR CONTROLLING A TRANSPORTATION SHAFT FOR OPTIMIZING MACHINING PERFORMANCE IN ACCORDANCE WITH THE WEIGHT OF A MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/019147
Kind Code:
A3
Abstract:
The present invention relates to a method for controlling a transportation shaft for optimizing machining performance in accordance with the weight of a material by preventing vibration and generated noise. For this purpose, the method for controlling a transportation shaft according to the present invention involves storing a look-up table in which a target load-to-motor inertia ratio is set in accordance with load inertia, detecting the acceleration of a motor and torque command data while moving the transportation shaft and detecting the weight of the material and the resulting load inertia in view of a motor side using the detected acceleration of the motor and torque command data, calculating a preset target load-to-motor inertia ratio corresponding to the detected load inertia using the look-up table, and adjusting an acceleration feedback gain to produce a load-to-motor inertia ratio in the calculated target load-to-motor inertia ratio.
