Estun Robot - Common faults and treatment methods of welding robots

1. Applicable welding methods and cutting methods: Generally, arc welding robots are only suitable for MIG/MAG welding, and there is no interference of high-frequency arc striking on the control and drive system of the robot. Whether it can be used for tungsten argon arc welding depends on whether the robot has a special anti-interference method.

Common faults of Estun servo drives 1. The LED light is green, but the motor does not move Reason 1: Motors in one or more directions stop the action. Solution: Check the +INHIBIT and -INHIBIT ports. Reason 2: The command signal is not on the driver ...

On June 22, 2020, Forbes China released the "2020 China's Most Innovative Enterprises List", which covers 50 innovative companies in 12 fields. With the technological innovation of a new generation of industrial robots, Estun Automation ...

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, ...

11. There is a servo motor with encoder feedback, can it be controlled by a servo drive with only a tachometer port? Yes, it is necessary to have an encoder-to-speed signal module. 12. Can the code disc part of the servo motor be disassembled? It is forbidden to disassemble it, because the inside of the disc ...

Servo system has an important position in electromechanical equipment, and high-performance servo system can provide flexible, convenient, accurate and fast drive. With the advancement of technology and the continuous development of the entire industry, the development trend of the traction system is to replace the traditional hydraulic, DC ...

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 motor cannot rotate after being energized, but there is no abnormal noise, no peculiar smell and smoke. 1. Cause of failure: (1) The power supply is not connected (at least two phases are not connected); (2) Fuse blowing (at least two-phase blowing); (3) The overcurrent relay is adjusted too small; (4) The wiring of the control equipment is incorrect. 2. Failure ...

1. The control system has the function of input and output. Most of the welding robots are programmed offline, and the technicians write the welding program in advance, and then input the welding program into the control system, and the control system intelligently identifies the weld standard through the sensor, selects the appropriate welding parameters, and ...

What are the main differences between the two? 1. The way of control is different Stepper motor: The rotation angle is controlled by controlling the number of pulses, and one pulse corresponds to a step angle. Servo motor: The angle of rotation is controlled by controlling the length of the pulse time. 2. Work ...

First, the control accuracy is different The step angle of the two-phase hybrid stepper motor is generally 3.6 ° and 1.8 °, and the step angle of the five-phase hybrid stepper motor is generally 0.72 ° and 0.36 °. There are also some high-performance stepper motors with smaller step angles. Such as Sitong company produced a kind of wire for slow wire ...

1. Initialize parameters Before wiring, initialize the parameters. On the control card: select the control mode; Reset the PID parameter to zero; When the control card is powered on, the enabling signal is turned off by default; Save this state to make sure that this is the status when the adapter is powered on again. Serving ...

1. The electromagnetic torque of the synchronous motor is the interaction between the rotating magnetic field of the stator generated by the power supply voltage and the main magnetic field of the rotor; 2. The intersection angle of the magnetic pole axis of the rotating magnetic field of the stator and the main magnetic field of the rotor is called the work angle; 3. When the power angle is zero, the electromagnetic torque is zero, and the work is zero.

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. Motor encoder alarm 1. The cause of the failure (1) Wiring fault; (2) electromagnetic interference; (3) Encoder hardware damage caused by mechanical vibration; (4) Pollution caused by the on-site environment. 2. Fault cleaning (1) Check the wiring and sweep away the fault ...

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. ...

1. The clamping action of the palletizer is too slow or the clamping stroke of the nail is insufficient. Causes and solutions: bolts are loose, and the front buckle or inner piece of the board machine is worn. The bolt can be tightened, paying attention to the correct position of the front buckle shaft. You can replace the front buckle or the inner piece of the board machine, after completing the above actions, test its function, if the line ...

Alarm code A25/A26/A27 refers to. Causes: 1. Power line problem; 2. Motor problems; 3. Mechanical transmission problems. Solution: 1. Observe whether the load rate is abnormal through Un003, if there will be a large instantaneous value, the machine ...

1. Different ways of control Stepper motor: The rotation angle is controlled by controlling the number of pulses, and one pulse corresponds to a step angle. Servo motor: The angle of rotation is controlled by controlling the length of the pulse time. 2. The workflow is different Stepper motor ...

A51: The robot spindle servo motor is abnormal. It could be a cable failure, a servo drive problem, a damaged spindle bearing, etc. A47: The servo motor is overheating. It may be because the external ambient temperature is too high, the servo motor is starting to break, and it cannot be cooled properly. A4 ...
