Estun servo motor fault repair method

The following preparations need to be made for starting when the motor is put into operation after installation or before it is put back into operation after being shelved for a long time: (1) Use compressed air to blow off the dust attached to the inside of the motor, and remove the wrapping paper at the windshield for new motors. Check whether the bearing grease is clean and suitable.

One: personal protection The safety operation procedures of welding robots are first of all to do a good job of personal protection, and the maximum scale of welding robot operations is set up outside the protective fence or cordon, and personnel are not allowed to enter the scale of their operations in the welding robot operation. In the process of welding robot operation, it is necessary to ...

1. The working principle of incremental encoder: The incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting pulse, and the number of pulses indicates the size of the displacement. To describe the pouring water, the incremental encoder is like, looking for a non...

Special attention should be paid to the following matters when the motor is regularly inspected during use: 1. The area around the motor should be kept dry, and no other objects should be placed inside and outside it The cleaning of the motor shall not be less than once a month, and the dust inside shall be blown off with compressed air during cleaning.

1) Excessive load; 2) Missing items; 3) Obstruction of air ducts; 4) The low-speed running time is too long; 5) The power supply wave is too large.

　　On December 11, the 2019 Golden Globe Award Annual Conference of the Industrial Robot Industry Event "Ecological Interconnection • Breaking Through Against the Trend" was held in Shenzhen. Zhu Chunhua of Estun Automation was invited to publish "How China's Intelligent Manufacturing Enters the Global ...

Mechanical 1. Bearing The bearing clearance on the lead screw housing is too large after wear, or the bearing roller elements and cages are severely worn due to the lack of grease in the bearing, resulting in excessive loads. After bearing wear, the clearance is too large, which will cause the coaxiality error between the center of the motor rotor and the center of the lead screw.

Troubleshooting and Detection Causes: 1. The servo amplifier calculates the load rate according to the effective value of the output torque. 2. If the value exceeds the overload level set in Pr5.12 (initial setting value = 115%), the protection will be generated. operate 3. From the amplifier ...

A servo control system is a feedback control system that is used to accurately follow or reproduce a process. In many cases, the servo system refers specifically to the feedback control system in which the controlled quantity (the output of the system) is the mechanical displacement or displacement velocity and acceleration, and its function is to make the mechanical displacement of the output (or ...

Point 1: Whether the speed of the motor is normal, whether there is speed jitter and stall (can be checked with a tachometer). Point 2: Whether the anchor bolts of the motor are loose, whether the foundation is intact, and whether there are debris around. Point 3: Whether the housing and coupling of the motor are in good condition, ...

On September 25, 2020, a group of 20 people from the Industry and Information Think Tank Alliance, led by Comrade Fan Bin, Deputy Director of the Department of Political and Legal Affairs of the Ministry of Industry and Information Technology, visited Estun Company for research. Dr. Wang Jiegao, President of Estun Automated Robot Research Institute, and Ms. Yuan Qin, Deputy General Manager, accompanied the visit and investigation. The experts visited ...

1. Torque control: The torque control mode is to set the size of the output torque of the motor shaft through the input of the external analog quantity or the assignment of the direct address, which is specifically manifested as if 10V corresponds to 5Nm, when the external analog quantity is set to 5V, the output of the motor shaft is 2.5Nm: if the motor shaft ...

1. Regularly check the encoder connection line of the servo motor and the power connector of the servo motor to confirm that they are firmly connected; 2. If the servo motor is connected to a reduction gear, the servo motor should be sealed with oil to prevent the oil from the reduction gear from entering the servo motor. ...

From the perspective of the protection response speed of the robot servo drive, Estun has a small amount of calculation in the form of torque, and the response to the control signal of the drive is fast. The azimuth form has a large amount of computation, and the response to the driver's control signal is slow. 1. If there is a relatively high demand for dynamic functions in sports...

1. Will the servo motor lose steps or walk inaccurately? The servo motor is controlled in a closed loop by the driver through the feedback of the encoder. After receiving each pulse command, the driver drives the motor to rotate at an angle, and checks whether the motor is rotated to a given point by the encoder

1: A motor deviation counter overflow error occurs when a long instruction pulse is entered. Causes and solutions (1) Generally, the gain setting is too large, and we can manually adjust the gain or adjust the gain automatically. (2) The load is too heavy, and it needs to be ...

1. Fast response time; 2. The control is convenient and flexible, and the control system is easy to implement; 3. High positioning accuracy, ordinary servo motor can reach 0.036 degrees; 4. There are many models, and different types can be selected according to different application environments; 5. Provide full closed-loop control ...

The servo control system is an operating system that can automatically control the mechanical movement of the test device according to the predetermined requirements. There are many classification methods for servo systems, and there are three common classification methods: 1. Classification according to the characteristics of the controlled parameters. 2. According to the type of drive element ...

Servo motor selection: Rotational speed (choose as required) Torque (the torque that needs to be output by the servo motor is calculated according to the load structure and weight, as well as the rotational speed) Moment of inertia (this parameter relates to the running accuracy of the servo on the mechanical structure, by the weight of the load structure ...
