Description
Technical Field
The invention relates to the technical field of servo drivers, in particular to a service life testing device and a service life testing method of a servo driver.
Background
The servo driver is also called servo controller and servo amplifier, and is one controller for controlling servo motor, similar to frequency converter acting on common AC motor, and belongs to the field of servo system. The servo motor is generally controlled by three modes of position, speed and moment, so that the high-precision positioning of a transmission system is realized, and the servo motor is a high-end product of a transmission technology at present. The servo driver is an important component of modern motion control and is widely applied to automation equipment such as industrial robots and numerical control machining centers. Especially, a servo driver applied to control an alternating current permanent magnet synchronous motor has become a research hotspot at home and abroad. Current, speed and position 3 closed-loop control algorithms based on vector control are commonly adopted in the current AC servo driver design. Whether the speed closed loop design in the algorithm is reasonable or not plays a key role in the whole servo control system, particularly the performance of speed control. In a servo driver speed closed loop, the real-time speed measurement precision of a motor rotor is important for improving the dynamic and static characteristics of the rotating speed control of the speed loop. In order to find the balance between the measurement precision and the system cost, an incremental photoelectric encoder is generally adopted as a speed measurement sensor, and a common speed measurement method corresponding to the incremental photoelectric encoder is an M/T speed measurement method. Although the M/T velocity measurement method has a certain measurement accuracy and a wide measurement range, the method has its inherent drawbacks, mainly including: 1) at least one complete code wheel pulse must be detected in the speed measuring period, so that the lowest measurable rotating speed is limited; 2) the 2 control system timer switches used for measuring the speed are difficult to keep synchronization strictly, and the speed measurement precision can not be ensured in the measurement occasion with large speed change. Therefore, the traditional speed ring design scheme applying the speed measuring method is difficult to improve the speed following and controlling performance of the servo driver.
People are increasingly high to servo driver product quality's requirement, and in order to improve servo driver's yields, guarantee servo driver when dispatching from the factory the quality, avoid the product to break down in the use early stage, all need test servo driver before manufacturing or dispatching from the factory, traditional test mode needs manual operation supervision, and efficiency is lower, is difficult to satisfy the production and processing demand.
