Estun servo drive has fault code A08

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.

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 ...

21. How to choose whether to use planetary reducer or spur gear reducer? Planetary reducer is generally used when high torque is required in a limited space, that is, small volume and large torque, and its reliability and life are better than that of spur gear reducer. Spur gear reducers are used for lower ...

structure AC servo motors are usually single-phase asynchronous motors, with two structural forms: squirrel cage rotor and cup rotor. Like ordinary motors, AC servo motors are constructed of a stator and a rotor. There are two windings on the stator, namely the excitation winding and the control winding, and the two windings are ...

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 ...

First, the working principle is different Stepper motor controller: It is an electronic product that can send out a uniform pulse signal, and the signal it sends out enters the stepper motor driver, which will be converted by the driver into a strong current signal required by the stepper motor to drive the stepper motor to run. Stepping ...

On March 11, Nanjing Estun Automation Co., Ltd. (hereinafter referred to as Estun) and Beijing Machinery Industry Automation Research Institute Co., Ltd. (hereinafter referred to as Beijing Institute of Automation) joined forces and reached a strategic cooperation agreement. Wang Zhenlin, Secretary of the Party Committee and Chairman of the Beijing Autonomous Institute, Estun Automatic ...

Common system failures during the welding process 1. Collision of guns: It may be due to the error of workpiece assembly or the inaccuracy of the TCP of the welding gun, you can check the assembly situation or correct the TCP of the welding gun. 2. Arc fault, unable to start the arc: it may be due to the fact that the welding wire does not contact the workpiece or ...

Estun Robotics FAQs. 　　After turning over the main switch of the control cabinet, there is no power, the cause analysis and treatment methods: Please check whether the power supply line of the electric control cabinet is correct; Please check whether the external power supply voltage meets the type of three-phase AC380V power supply robot Please acknowledge that the cabinet is broken...

Speed regulation of DC motors Constant power weak magnetic upward speed regulation, the magnetic field governor can be adjusted until the speed reaches the required value, but shall not exceed the maximum speed allowed by the technical conditions. Constant torque loads can be slowed down by step-down or armature string resistors. Downtime of the DC motor ...

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 ...

6. What should I pay attention to when using the motor? Check the following before powering on: 1) Whether the power supply voltage is appropriate (overvoltage is likely to cause damage to the drive module); The +/- polarity of the DC input must not be misconnected, and the motor model or current setting on the drive controller ...

1. Estun servo motor maintenance - 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 model of the servo drive and the motor does not match ...

(1) Small inertial DC servo motor The small inertia straight sinking servo motor is named because of the small rotation of the inertia basin. This type of motor is generally hydromagnetic, and there are three types of armature windings: phaseless armature type, printed armature type and coreless armature type. Because the small inertia DC motor minimizes the armature's ...

The position data of each axis of the industrial robot is stored through a backup battery, which should be replaced regularly (one and a half years). In addition, if the backup battery shows a voltage drop alarm, the battery should also be replaced in time. 1. Replace the controller motherboard battery Program and system variables are stored in the main ...

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 main function is to use it in a closed ring, transmit the signal to the system at any time, and at the same time correct its own operation with the signal given by the system. Servo motor ...

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 ...

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...

16. Is it safe to use a DC power supply voltage greater than the rated voltage value to drive the motor? Normally this is not a problem, as long as the motor is operating within the set speed and current limits. Because the motor speed is proportional to the motor line voltage, choosing a certain supply voltage will not cause ...

The 2021 China International Medical Equipment Fair will be held from May 13 to 16 at the National Convention and Exhibition Center in Shanghai. Estun Medical will exhibit the unilateral and bilateral versions of the Burt Upper Limb Rehabilitation Training System, which is more suitable for the full-cycle rehabilitation training program of the rehabilitation population, and includes adaptation ...
