Maintenance of AC servo drive of electronic universal test machine

The power of the electronic universal test machine comes from the AC servo driver. Generally, the AC servo driver uses Panasonic AC servo or domestic brand servo motors and drivers. The driver is a perfect combination of electronic and mechanical deceleration technology. The speed of the motor driver is controlled by the microcomputer to control the measurement and control software to change the movement speed of the electronic universal test machine. Drivers and servo motors are very critical components in the electronic universal test machine. Electronic universal test machines all use AC servo motors, while most of the southern manufacturers use stepper motors or DC motors to control the displacement speed through the inverter. This is actually the most primitive control method. The advantages of AC servo motors are their characteristics such as accurate control accuracy, small error, low noise, maintenance-free, durable, etc. Then the AC servo driver of the electronic universal test machine also needs to be maintained during use: How to maintain it? Please see the introduction below.

Maintenance of AC servo drive of electronic universal test machine

1. After the service cycle of the host equipment exceeds one year, the servo drive of the electronic universal test machine should be maintained. Before opening the host case, the power supply of the host must be cut off. The driver has a digital window. It must be debugged and maintained after the controller window number disappears for 5 minutes.

2. Use a multimeter to measure whether the power supply voltage is within the driver's power supply voltage range, whether there is any contaminated liquid in the motor and the surrounding environment, and use a hot air gun to blow away the dust inside the controller to maintain a clean and dry environment to extend the service life of the controller.

3. When the electronic universal testing machine is not used for a long time, the total power supply of the test machine should be turned off and the power should be kept on for 15 days and running for 30 minutes to ensure that the electronic components and mechanical parts are fully lubricated.

4. There are many circuit boards in the electronic universal test machine. As time goes by, the internal circuit board will cause corrosion to the circuit due to air humidity. This reason must be informed to the electronic universal test machine manufacturer in advance to prevent corrosion of the internal circuit. You can also spray preservatives on the circuit board to reduce the faults of the electrical parts and improve the service life.

5. When maintaining the motor and controller of the electronic tension tester, remember to check the power cord, control cord, signal cord, etc., and should have stable grounding protection. In order to prevent damage to the circuit caused by thunderstorms.

The above is a related introduction to the maintenance of the AC servo drive of the electronic universal test machine. I hope everyone will pay attention to these points when using the machine. We should pay attention to the problems found during use of the test machine and promptly eliminate them to avoid errors in your test results. It is to regularly check and correct the test machine to ensure the normal use of the test machine.
