Estun servo motor - the place where the daily maintenance of servo motor needs attention

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...

1. Fault phenomenon: The uneven distribution of the magnetic field of the ions, the unbalanced three-phase current aggravates the vibration and noise of the motor during operation, and the motor cannot be started when it is serious, and a large short-circuit current is generated in the short-circuit coil, which causes the coil to heat up rapidly and burn out. 2. Causes: ...

One: machine cleaning First and foremost, disconnect the power supply and remove debris around the machine. Use a clean cloth to wipe the surface of the machine to ensure that it is free of dust, grease and other impurities. For the cleaning of the inside of the machine, it needs to be operated by professionals. Two: Look at the machine parts ...

1. The motor temperature is too high or the smoke is faulty Cause: 1. Excessive load 2. Two-phase operation 3. Air duct obstruction 4. The ambient temperature increases 5. Stator windings are short-circuited between phases or turns 6. Stator winding grounding 7. The power supply voltage is too high ...

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. How to choose the servo motor and stepper motor correctly? Mainly depends on the specific application, simply put, it is necessary to determine: the nature of the load (such as horizontal or vertical load, etc.), torque, inertia, speed, accuracy, acceleration and deceleration and other requirements, upper control requirements (such as port interface and ...

1. What is "inertia matching"? 1. According to Newton's second law: "The required moment T of the feed system = the transmission inertia of the system J×angular acceleration θ angle". The acceleration θ affects the dynamic characteristics of the system, the smaller θ, the more time from the controller to the completion of the system's execution.

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 ...

Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is a kind of auxiliary motor indirect transmission device. The servo motor can make the control speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. Servo motor rotor speed ...

1. Position proportional gain Set the proportional gain of the position ring adjuster; The higher the set value, the higher the gain, the greater the stiffness, and the smaller the position lag under the same frequency command pulse. However, too large a value may cause oscillation or overshoot; The parameter values are determined by the specific servo system type ...

Problem 1: The reason why the servo motor alarms the overload If the drive resistance is too great, check the drive system. Q2: What is the difference between stepper motor and servo motor overload capacity? Question 3: Is the servo motor overload necessarily related to the current? As the motor torque output ...

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. ...

There are many types of motors, and the ordinary motor we commonly use is the induction motor, although it and the servo motor are both motors, there are certain differences: 1. The speed of ordinary motors is too fast, the torque is too small, and because there is no feedback from itself, it is usually impossible to achieve accurate control.

As the engine that controls the operation of the servo system, the servo motor is a kind of indirect transmission device of the auxiliary motor, so how to use it correctly is a very critical task. The following motion controller uses analog signal control servo motor as an example to illustrate. 1. Initialize Parameters ...

1. Overload alarm A04 1. The wiring of the servo motor is wrong or the wiring is leaking (1) The U, V, and W phase wires of the motor are connected incorrectly (2) Whether the insertion of the connector on the servo motor side is defective 2. The type of servo drive and motor does not match View drive type ...

1. Lubricating oil is used in various types of machinery, the role is to reduce friction, so as to protect the liquid lubricant of machinery and processed parts, mainly playing the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. 2. Grease is a relatively viscous grease-like semi-solid. It is used in mechanical ...

Main role The main functions of the servo system include the control of the output shaft located in the distance by the input shaft in the absence of mechanical connection, so as to realize long-distance synchronous transmission; Enables the output mechanical displacement to accurately track electrical signals, such as recording and indicating instruments, etc.; Go to the low power command signal ...

The AC servo system includes: servo drive, servo motor and a feedback sensor (generally servo motor comes with an optical encoder). All of these components operate in a controlled, closed-loop system. The drive receives parameter information from the outside and then sends a certain current to the motor ...

11. What is the principle of parameter adjustment of speed loop and position loop of servo drive? In addition to the performance of the motor and the drive, the adjustment of the drive parameters is also a very critical factor. The main performance parameters of the servo drive ...

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 ...
