Servo drive burnout cause, servo drive serious heating what s going on?

It is also possible that the deceleration time is too fast, and the respawn resistance is insufficient, resulting in damage to the substation module.

Servo drives.

Servo drive is a kind of controller used to control servo motor, servo drive.

Its function is similar to that of an inverter acting on a normal AC motor and is part of the servo system.

At present, the mainstream servo drives all use digital signal processors (DSPs) as the control core, which can realize more complex control algorithms, and digitalize, network and intelligentize matters. The power device generally adopts the drive circuit designed with the intelligent power module (IPM) as the core, and the IPM integrates the drive circuit inside, and has fault detection and protection circuits such as overvoltage, overcurrent, overtemperature, and undervoltage, and also adds a soft-start circuit in the main circuit to reduce the impact of the start-up process on the driver.

The power drive unit first rectifies the input three-phase electricity or mains power through the three-phase full-bridge rectifier circuit to obtain the corresponding direct current. After the rectified three-phase electricity or mains, the three-phase permanent magnet synchronous AC servo motor is driven by the frequency conversion of the three-phase sinusoidal PWM voltage inverter. The whole process of the power drive unit can be simply said to be the process of ac-dc-ac.

The main topology circuit of the rectifier unit (AC-DC) is a three-phase full-bridge uncontrolled rectifier circuit.

Servo drives can generally adopt three control modes of position, speed and torque, which are mainly used in high-precision positioning systems, and are currently the high-end of transmission technology. With the large-scale application of servo system, the use of servo drive, servo drive debugging, and servo drive maintenance are all important technical topics of servo drive today, and more and more industrial control technology service providers have carried out in-depth technical research on servo drives.

1. Is your servo drive brand new? If it is second-hand, it is estimated that it is a circuit board and electronic components.

Caused by aging.

2. Is the servo-driven Qingna filial piety device always in the overload working state, if it is to pay attention, it will heat up for a long time.

It's going to burn too much.

3. Set the PID parameters, or set the servo motor by itself.

parameters. Personally, it is recommended that the servo system should be bought with the same brand, for example, the reputation you buy is a Jerett servo motor, which is equipped with a Jerett's servo drive, so that the benefits of matching are not easy to go wrong, and the service is also convenient. If it is a servo motor with a third-party servo drive, it will be more troublesome when debugging.

The driver is seriously heated, first check whether the servo motor line wiring is abnormal, and secondly, whether the circuit board of the driver is abnormal, whether there is a super negative key and a good situation of Sakura?

You adjust the inertia ratio parameter of the driver too much, see what the initial value of the manual is, and see how much you adjust it, and lower the inertia ratio parameter.

A short circuit is called a phase-to-phase short circuit. Either way, Lapei will increase the electric and slag flow of a certain phase or two phases, causing partial heating, and damaging the insulation to damage the motor. Winding break refers to the collision of the stator or rotor windings of the motor.

Summary. Hello, these are just some of the reasons for servo drive burnout maintenance, so when the servo drive burns out, do not blindly disassemble and repair, otherwise you need to find a professional maintenance person to detect the cause of the failure and propose**. Finally, decide whether you want to repair it or not.

Hello, there are many reasons why the servo drive burns out, among which the capacitor burns out the most, so what causes the capacitor to burn out and burn out? To summarize the following points:

1.Capacitor model does not match 2The quality of the capacitor is too poor to be broken down3

If there is no problem with the matching and quality, the standby may be caused by damage to other components of the circuit4Mistaken damage usually means that the capacitor may still be damaged and misjudged. 5.

Broken foot caused by human causes 6Installation environment issues.

No, once the overload alarm is triggered, the servo drive will stop output, and the servo motor will stop running, and the motor will not be burned. The servo motor has overcurrent protection, and the motor will not be burned out when it stops after overload, and it can be used after eliminating the alarm.

The intelligent power module IPM inside the servo amplifier has built-in fault detection circuits such as overvoltage, overcurrent and overheating, so when the motor drive load is accelerating or decelerating, the output torque of the motor is greater than the rated torque of the motor and lasts for a short time, the amplifier will have an overload alarm.

In addition, a simple way to judge the fault of the servo motor: after removing all the wiring of the motor, rotate the motor bearing, if you can feel the obvious resistance, the rotation is not smooth, the fuselage coil is burned out, and the coupling is not properly assembled, it is easy to knock the encoder out, you can shake the motor encoder part, if you can hear the sound of the encoder fragments, the encoder is knocked out.

Check the power line, contactor, relay, power leakage protection and event module and other circuits to confirm that the power supply line is normal. 2.Check the internal hardware of the servo drive:

Replacing the servo driver motherboard or replacing the drive controller, checking the lithium battery, control circuit, and drive control in the circuit can solve the problem of the servo drive virtual driver not being powered on. 3.Check the software controls:

Check whether the signal source set by the software is normal and whether the vector control command can be executed normally. 4.Other failures:
