[0002] With the continuous development and progress of demand and technology, inkjet printers have become one of the commonly used printing equipment in the advertising industry. They are mainly used to print large-area advertising posters, high-end printed parts and various decorative materials. The structure is complex, involving multiple technical fields such as computer information processing, machinery, automatic control, and motor drive. The material retracting and discharging control system is one of the subsystems. The accuracy requirements are very high, and the accuracy is affected by two aspects. One is the inherent control accuracy of the longitudinal motor and transmission system, which has been fully considered in the design of the inkjet printer system. Generally, there is no problem. The second is that on the printing plane, the longitudinal motor On the left side, the tension of the material should be kept constant while the material is driven by the longitudinal motor, otherwise it will cause a small longitudinal transmission error. However, the control system of the inkjet printer on the market does not have the function of eliminating this error. When the receiving / discharging motor drive system is overloaded or blocked for a long time, the receiving / discharging motor will be damaged. Currently, the receiving / discharging control system on the market does not have a motor overload protection function, and Due to the large load range of the motor and the large number of motor power levels, the alarm threshold parameters are very different, which is a difficult point in the use of the alarm circuit. If the threshold is high, the alarm circuit will not work, and if the threshold is low, it will easily cause false alarms and affect normal work. For this reason, the present invention proposes an advanced industrial inkjet printer retractable material control system
