Servo driving system cable testing device

Abstract

The invention discloses a servo driving system cable testing device which comprises an upper computer, a microprocessor, a starting button, a display screen and a cable switch board. The cable switchboard comprises an SPI bus interface, a serial-parallel converting chip, a cable input interface and a cable output interface. The upper computer is in communication connection with the microprocessor. The starting button starts the working power supply of the microprocessor. The display signal output end of the microprocessor is connected with the signal input end of the display screen. The SPI bus interface is in communication connection with the SPI bus port of the microprocessor and the serial-parallel converting chip. The signal output end of the serial-parallel converting chip is connected with the cable input interface. The signal input end of the serial-parallel converting chip is connected with the cable output interface. The device overcomes defects in a traditional cable testingmode and can quickly and automatically test various cables used in different service driving systems. Furthermore the device has advantages of facilitating field testing of cable quality, improving testing efficiency and preventing testing omission and testing errors.

Description

technical field [0001] The invention relates to a cable detection device for a servo drive system. Background technique [0002] With the wide application of servo drive systems in various industries, more and more cables are used in servo drive systems. These cables include communication cables connected to host computers and encoders and power cables connected to motors. The upper computer communication cables include position control, speed control, torque control, I / O control and other cables. The types of encoders include incremental photoelectric encoders, wire-saving photoelectric encoders, resolvers, and magnetic encoders. etc., the communication cables are different; because there are many types of host computers, encoders and motors, there is currently no ready-made equipment on the market that can detect these different cables at the same time. Cable point-to-point measurement has low automation efficiency and is prone to errors, resulting in missed and false det...
