Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] The detection method of the industrial robot servo drive based on the electric fast transient pulse group, the specific steps are as follows:

[0037] Step 1, such as figure 1 As shown, a detection system is built; the detection system includes a switching power supply 1 , a controller 2 , a host computer 3 , a capacitive coupling clip 4 and a coupling and decoupling network 5 . The model of controller 2 is PLC with model DVP-50MC-60T. The coupling and decoupling network 5 includes a coupling device and a decoupling device for filtering irrelevant signals and coupling the interference pulse signal to the power line of the equipment under test. The capacitive coupling clip 4 couples the interference pulse signal to the signal line of the equipment under test. The switching power supply 1 steps down the 220V power supply to a 24V power supply to supply power for the...

Abstract

The invention discloses an electric fast transient-based industrial robot servo driver detection method. The electric fast transient is a common and extremely harmful type of electromagnetic interference for an industrial robot control power supply system and has a very rich harmonic component. The method comprises the following steps: 1, a detection system is built; 2, three working conditions and interference pulse parameters of the servo motor are set; 3, a servo motor is selected according to a detected servo driver, and wiring is carried out; and 4, interference pulses are inputted respectively under each working condition to determine the ability of the detected servo driver resisting the electric fast transient. The electric fast transient testing method provided in the invention does not exist in the existing industrial robot field, is particularly applied to the field of industrial robot servo drivers, has high innovation and engineering applicability and improves the reliability study on the industrial robot servo driver.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic compatibility testing, and in particular relates to a detection method for an industrial robot servo drive based on electric fast transient pulse groups. Background technique [0002] In recent years, with the development of the intelligent manufacturing industry of industrial robots, servo drives, as one of the four core components of industrial robots, have been widely used in the field of industrial robots. The servo driver is a control device that controls the operation of the servo motor. It can achieve closed-loop control of the servo motor through position, speed, torque, etc. [0003] However, in the work of industrial robots, electrical fast transient bursts, as a common and extremely harmful type of electromagnetic interference in industrial robot control power systems, have very rich harmonic components. Electrical fast transient burst interference is mainly manifested as commo...
