Title:
MULTI-AXIS MOTOR CONTROL DEVICE RESONANCE FREQUENCY DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/064239
Kind Code:
A1
Abstract:
There is provided a multi-axis motor control device resonance frequency detection device capable of detecting resonance frequency of the other axis affecting an operation axis in a machine having multiple axes. The multi-axis motor control device resonance frequency detection device includes a plurality of motor control systems having motors (31, 32) for driving machines (41, 42) and controllers (21, 22) for driving the motors (31, 32). Each of the motor control systems includes detectors (51, 52) for detecting the operation amount of the machines (41, 42), signal processors (61, 62) for frequency-analyzing the signal of the detectors (51, 52) and outputting it as a resonance frequency, and output devices (81, 82) for putting the signal of the signal processors (61, 62) into a graph or a numerical value for output. There is further provided an instruction generator (11) for supplying a control instruction transferring oscillation to the machines (41, 42) to the motor control system, so that signals of a plurality of detectors (51, 52) are input to the signal processor (61) and output as a resonance frequency.
