1、在主机设备使用周期超过一年后，应对电子式万能试验机的伺服驱动器进行维护。在打开主机机壳前，必须将主机的供电电源切断，驱动器都有显示数字窗口，必须在控制器窗口数字消失5分钟后进行调试保养。

1. After the service life of the host equipment is more than one year, the servo driver of the electronic universal testing machine should be maintained. Before opening the main machine shell, the power supply of the host must be cut off. The driver has a digital display window. The debugging and maintenance must be carried out after the number in the controller window disappears for 5 minutes.

2、用万用表测量供电电压是否在驱动器供电电压范围内，电机及驱动器周边的环境有没有污染性液体，用热风枪吹干净控制器内部的灰尘，保持干净干燥的使用环境来延长控制器的使用寿命。

2. Use a multimeter to measure whether the power supply voltage is within the power supply voltage range of the driver, and whether there is any polluting liquid in the surrounding environment of the motor and the driver. Blow the dust inside the controller with a hot air gun, and maintain a clean and dry service environment to prolong the service life of the controller.

3、在长期不使用电子万能试验机的时候，应关闭试验机总电源，并保持15天开机运行30分钟，保证电子元器件部分及机械部分充分得到润滑。

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

4、电子万能试验机中有很多电路板，随着时间的增加内部电路板会因空气湿度对电路造成腐蚀，这个原因就要提前对电子万能试验机厂家告知对内部电路进行防腐处理，也可以对电路板进行喷施防腐剂，从而降低对电气部分的故障，提高使用寿命。

4. There are many circuit boards in the electronic universal testing machine. With the increase of time, the internal circuit board will corrode the circuit due to air humidity. For this reason, it is necessary to inform the manufacturer of the electronic universal testing machine in advance to carry out anti-corrosion treatment for the internal circuit, or spray anti-corrosion agent on the circuit board, so as to reduce the failure of the electrical part and improve the service life.

5、在保养维护电子拉力试验机电机及控制器时，切记检查各电源线、控制线、信号线等，应有稳定的接地保护。以防雷雨天气造成损坏电路现象发生。

5. When maintaining the electric motor and controller of the electronic tensile testing machine, it is important to check all power lines, control lines, signal lines, etc., and have stable grounding protection. In order to prevent the occurrence of circuit damage caused by thunderstorm weather.

以上是对电子式万能试验机交流伺服驱动器的维护保养的相关介绍，希望大家在使用该机时注意这几点，要经常注意试验机的在使用过程中发现的问题，及时排除，以免您测试结果产生错误。在就是对试验机定期检查校正，保证试验机的正常使用。

The above is the introduction of the maintenance of the AC servo driver of the electronic universal testing machine. I hope you can pay attention to these points when using the machine. You should pay attention to the problems found in the use of the testing machine, and eliminate them in time, so as to avoid errors in your test results. It is to check and correct the testing machine regularly to ensure the normal use of the testing machine.

电子万能试验机的动力来源于交流伺服驱动器，一般交流伺服驱动器采用的是松下交流伺服或国内品牌的伺服电机及驱动器，该驱动器是电子与机械减速技术的完美结合，通过微机控制万能试验机测控软件控制电机驱动器的转速改变电子式万能试验机的移动速度，驱动器和伺服电机在电子式万能试验机中是非常关键的部件，电子万能试验机都是采用交流伺服电机，而南方一些厂商大部分采用步进电机或直流电机通过变频器控制位移速度，这其实是最原始的控制方式了，交流伺服电机的优点在于其控制精度准确、误差小、噪音低、免维护、经久耐用等特点，

The power of electronic universal testing machine comes from AC servo driver. Generally, the AC servo driver adopts Panasonic AC servo or domestic brand servo motor and driver. The driver is the perfect combination of electronic and mechanical deceleration technology. The speed of motor driver is controlled by microcomputer control universal testing machine measurement and control software to change the moving speed of electronic universal testing machine, The driver and servo motor are very important parts in the electronic universal testing machine. The electronic universal testing machine adopts AC servo motor, while some manufacturers in the South mostly use stepping motor or DC motor to control the displacement speed through frequency converter, which is actually the most original control mode. The advantages of AC servo motor lie in its accurate control accuracy, small error and noise Low tone, maintenance free and durable,
