The monitoring program or data of servo motors with different specifications and different powers respectively give the CNC machine tool servo system fault analysis and maintenance servo system the highest failure rate of CNC machine tools. The technical data of imported AC and DC servo control systems is scarce, spare components The complex model makes it extremely difficult to repair. This article introduces the Japanese Dongrong Software AC servo system and the German Siemens AC drive device analysis and troubleshooting. Without the need for an external device (such as a programming board), you can easily track the working status, display (digital display) work content, and adjust various states of the servo control system (such as motor speed) directly through the operation (key or menu) program. , current position, deviation, machine feed speed, motor current, electric heating value, motor phase sequence, fault category, etc.; self-test and trial run without external signal. The fault range of the whole machine can be judged in a short time (in minutes or seconds). Its cost performance is slightly higher than that of digital AC servo. It is a relatively advanced product with better performance than European and American products. It is a typical software AC servo control system (there are other series of products from Japan, Yamakawa, Mitsubishi, etc.). Depending on the characteristics of these products, the focus of routine maintenance can be on inspection, maintenance and repair. Use the check display function such as sequential input and output, alarm, and parameter change to confirm. Use the button to move to check the display range, then use the buttons to select the desired inspection item. The sequential input and output checks are displayed for each of the seven segments. The vertical line of the upper half of the light pipe corresponds to the input signal, and the lower half corresponds to the output signal, that is, the on/off state of the display signal. It can also be used by the oscilloscope to monitor (speed command voltage), (current limit command voltage), (analog monitor), (analog signal ground) and (phase current at (plug)), phase current) , (analog signal ground) to check and judge the fault. Use the alarm number in the fault state (on the panel of the servo unit) to check the fault. Now we will list the common parts (single units) necessary for emergency repair in the servo system of the Dongrong software AC servo unit and servo motor, etc., and supply the high-power drive module with good and bad judgment methods.
