Buke servo - introduction of four common servo control systems

1. Wipe the motor. Remove the dust and sludge on the outside of the motor base in time. If there is a lot of dust in the environment, it is best to clean it once a day. 2. Check and wipe the motor terminals. Check whether the junction box wiring screws are loose or burned. 3. Check the screws of each fixed part ...

1. The first difference between a servo encoder (synchronous service motor) and an ordinary encoder is that it provides sensing signal feedback for the commutation of the starting current. The main performance indicators of servo motor encoders are shift rate, accuracy, and repeatability. 1) Routinely mentioned 17-bit to 25-bit singleturn resolution ...

Due to the limitations of technology and environmental adaptability, the surface touch screen will not be able to be used normally due to water droplets, dust and other pollution not being treated in time, so the touch screen also needs regular maintenance like ordinary machines. And because the touch screen is a variety of electrical equipment high ...

(1) Azimuth share gain Sets the share gain of the azimuth ring adjuster. The higher the set value, the higher the gain, the greater the stiffness, and the smaller the azimuth lag under the same frequency command pulse. However, too large a value may cause vibration or overshoot. The parameter values are determined by the detailed servo ...

1. Encoder connection line failure: This kind of failure has the highest probability and is often encountered in maintenance, so it should be a priority factor. Often, encoder cables are open, short, or in poor contact, so the cable or connector needs to be replaced. Special attention should also be paid to whether the cable is loose and causes open soldering or ...

A stepper motor driver is an actuator that converts electrical impulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to roll a fixed viewpoint (called the "step angle") in the set direction.

1. If the servo motor is an AC motor, it is a DC inverter air conditioner for speed regulation; If the servo motor is a DC brushless DC motor, it is the DC power supply DC transformer speed regulation; All servo motors can be used as "PLC motor speed regulating power supply circuit servo motor". 2、 ...

1. Check whether the power supply voltage is stable and whether the logic voltage is within the input range of the driver, and use a separate power supply to supply power to the logic circuit; 2. The target current limit is set too small, and the current limit is increased within the allowable range. If you still can't find the reason for the above solutions, please ...

1. Resistive touch screen The most important part of a resistive touchscreen is a resistive thin-film screen that matches the surface of the display very well. This is a multi-layer composite film based on a layer of glass or hard plastic plate, coated with a transparent metal oxide (ITO indium oxide, transparent conductive ...

6. The motor vibrates greatly during operation (1) The cause of the failure (1) Due to excessive clearance of worn bearings; (2) uneven air gap; (3) Rotor imbalance; (4) Bending of the rotating shaft; (5) The coaxial axis of the coupling (pulley) is too low. (2) Troubleshooting ...

1. Check whether the joints of each connecting line are loose; 2. Check whether there is a conflict between the serial port and the abort number, and if there is a conflict, the resources should be adjusted to circumvent the conflict. Then check whether there are gaps in the surface layer of the human-machine interface, and if there are gaps, they should be replaced immediately. It also needs to be inspected ...

1. Install the rotating shaft on the equipment casing, and the spindle and the equipment casing are supported by bearings. 2. Install the stator on the stop of the equipment housing and press it with the stator pressure ring. 3. Put the rotor into the inner hole of the stator, pay attention to protect the stator at the same time, and use the connecting bolt to connect the rotor with the ...

1. The motor temperature is too high or the smoke is faulty Cause: 1. Excessive load 2. Two-phase operation 3. Air duct blockage 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 ...

1. Change the rotational speed by changing the frequency of the mains supply This is a common method of speed adjustment for AC motors. The power supply frequency can be adjusted to the desired speed by adjusting the inverter, transformer, and other equipment. 2. Change the rotational speed by changing the voltage In some special cases ...

The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal, and can respond quickly, in the automatic control system, used as an actuator, and has an electromechanical time constant...

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) Control ...

Human-machine interface refers to the field where man and machine contact or interact with each other in information exchange and function, which facilitates our lives, but it is inevitable that there will be some failures when using human-machine interface machines, and how should we deal with these failures. First, the human-machine interface is normal but the computer is not...

1. Please ensure that the environment is clean and avoid oil. When used in dusty and humid places, although the protection level of the servo motor is very high, it will be easy to cause problems if it is often used in such an environment. 2. Regularly check the use of the servo motor to see if there is any damage outside.

1. The indicated value is large (or out of range). According to the investigation of our staff, this kind of problem often appears in the atmospheric pressure workshop. When we find that the counterweight of the float in the float level gauge is at a low point, the liquid level must be very high at this time, and the glass plate is inconsistent with the indication of the instrument.

1. Comparison link The comparison link is to compare the input command signal with the feedback signal of the system to obtain the deviation signal between the output and the input, which is usually implemented by a special circuit or computer. 2. a controller The controller is usually a computer or PI...
