Buke servo motor - the requirement of the servo feed system

1. AC motors are cheaper to manufacture. 2. With the development of vector frequency conversion technology, it has been possible to simulate direct current with frequency conversion motors 3. Compared with DC motor, it has enough advantages in simple structure, easy maintenance, low environmental requirements, energy saving and improved productivity.

1. Servo motor pulse control mode In some small stand-alone equipment, the use of pulse control to achieve the positioning of the motor should be the most common application method, this control method is simple and easy to understand. The basic control idea: the total pulse amount determines the motor displacement, and the pulse frequency determines the ...

1. For new or long-term out-of-service motors, the insulation resistance between the windings and the windings to the ground should be checked before use. Usually for motors below 500V, 500V insulation resistance meter is used; 1000V insulation resistance meter for 500-1000V motors; 2500V insulation resistance meter for motors above 1000V. Insulated ...

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. Clean the motor and remove the dust and sludge outside 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 fixing part, ...

1. Fault code: E-01, E-02 Significance: The parameters are initialized incorrectly during power-on. Cause: Incorrect parameter settings. Solution: Power back on, if the fault is still reported, you need to force the parameter initialization, if it is repeated many times, it cannot be solved.

There are two main control methods of DC servo motor: one is armature voltage control, that is, under the condition that the stator magnetic field remains unchanged, the speed and output torque of the motor are controlled by controlling the voltage signals applied to both ends of the armature winding; The other is the excitation field control, that is, by changing the ...

Recently, the Ministry of Industry and Information Technology of the People's Republic of China has completed the review of the fourth batch of specialized, special and new "little giant" enterprise cultivation, and publicized the list of enterprises that have passed the review.

1. Please check the motor power line to confirm whether there is a short circuit in the phase wire of the motor 2. If there is no short circuit in the phase line of the motor, it is determined that the internal power tube problem of the driver is determined

(1) Encoder failure: It refers to the failure of the components of the encoder itself, resulting in its inability to generate and output correct waveforms. In this case, the encoder needs to be replaced or its internal components repaired. (2) Encoder connection cable failure: the probability of this fault is the highest, and the maintenance ...

1. Servo motor encoder is a product installed on the servo motor, which is equivalent to a sensor. 2. Do speed closed-loop and azimuth closed-loop to complete accurate speed regulation and accurate azimuth control. 3. The servo motor has its own encoder, which can be converted into servo electronic gears.

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 ...

1. Check the servo motor to ensure that there is no fatal damage outside; 2. Check the fixed parts of the servo motor to ensure that the connection is strong; 3. Check the output shaft of the servo motor to ensure the rotation and circulation; 4. Check the encoder connection line of the servo motor and the ...

1. Communication cannot be connected. 2. The interference in the process of data transmission will increase (sometimes it is not bad, but the connection between the host computer and the servo is incorrect, or there is a falling off, which is a very common problem). 3. The motor will run, but it will not work according to the instructions given by the servo ...

First, the common causes of such faults caused by mechanical oscillation (acceleration/deceleration) when the motor is powered on are: (1) The pulse encoder is faulty. At this time, the servo system should be checked to see if it is stable, whether the circuit board maintenance detection current is stable, and at the same time, the electrical ...

In terms of the response speed of the servo drive: the torque mode has the smallest amount of calculation, and the driver responds the fastest to the control signal; The position mode is the most computationally intensive, and the driver is the slowest to respond to the control signal. When there are relatively high requirements for dynamic performance in motion, it is necessary to ...

1. How to deal with the servo motor not running when there is pulse output? a. Monitor the current value of the pulse output of the controller and whether the pulse output light is flashing, and confirm that the command pulse has been executed and the pulse has been output normally; b. Check the control cable from the controller to the driver, ...

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. 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 ...

Point 1 When the servo motor jitters at zero speed, the gain should be set high, which can reduce the gain value. If the alarm stops when starting, the most likely is that the phase sequence of the motor is incorrect. Point 2 1. When the PID gain adjustment is too large, it is easy to induce...
