High-frequency leakage current return line with a motor-driven cable, low inductance return line with a non-shielded cable, and motor drive control system using the cable, and, injection molding machine or robot or numerically controlled machine tools

摘要

By the effects of stray capacitance in the motor began to appear by the [problem] Recently, with the high speed and high efficiency of the inverter, pulse rise time becomes shorter, the leakage current to the peripheral device occurs, malfunction peripherals possibility that the cause has occurred. As well as reducing the inductance of 5 high-frequency leakage current return line By flanking in close proximity near the 5 high-frequency leakage current return line comprising a plurality of article or article 1 to the drive insulation core wire 2 consisting of [SOLUTION] Multiple Article , twisted and are arranged substantially parallel to the length direction of 5 high-frequency leakage current return line and the driving insulating core wire, high-frequency leakage current return lines subjected to sheath 8 without using the shield on the outside of the line fit Ri motor-driven cable month.
