CNC equipment is increasingly used in manufacturing because of its high efficiency, high flexibility and low cost. Our company has purchased CNC equipment since the 1980s. These equipments play a key role in the manufacturing precision of our company, which guarantees the company's varieties, quality and economic benefits. In numerical control equipment, the position control system functions as an actuator. Accurately control the coordinate position of the moving parts of the machine to quickly and accurately track the command movement. All CNC equipment of our company adopts closed-loop control. The closed-loop position control system, also known as position servo system, works on the basis of feedback control principles.

In order to carry out feedback, it is necessary to have detection elements to detect and signal the controlled variables, so as to achieve the purpose of control, the position control device is mainly composed of the detection component position control module and the feedback control. The installation and debugging of the detection component is an important part of the CNC system. Its function is to detect the displacement and send the feedback signal to form a closed loop control. The machining accuracy of CNC equipment is mainly determined by the accuracy of the inspection system. The smallest unit that the position detection system can measure is called the resolution. The resolution depends not only on the sensing element itself, but also on the measurement line and mounting clearance.

If it is seen on the programmer, only the signal is not, which means that the spindle is forbidden because the lubrication is not ready, we can continue to find the conditions that the lubrication is not ready. According to the above method, the signal state can be continuously detected, and then according to the drawing. Take the start lubrication to fill the lubricant, adjust the pressure valve, and eliminate the alarm. Finding Machine Faults with Output Bit Indicators Machine spindle shifts often fail, most of which are caused by electrical limit switches. Finding is very difficult.
