CC-PCF901 51405047-175 Main Motor Frequency Converter

CC-PCF901 51405047-175 The upper and lower units use RS485 communication, which is convenient and reliable. For multi-color machine, the safety factor is very important. In the design, each unit should take into account both the safety control, including the unit’s emergency stop, safety buttons; but also to consider the convenience of operation, including each unit should be a positive point, negative point button. Therefore, on the one hand, the input point increases a lot; on the other hand, the line is also very inconvenient. The use of dual-machine communication, can be a good solution to this problem, the alignment of the unit can be in accordance with the principle of proximity, into the closer to it in the control cabinet, both to save the alignment, but also to facilitate the control.

CC-PCF901 51405047-175 is a high-precision machinery, the good or bad of the print lies on the one hand in the mechanical processing and the accuracy of the installation, on the other hand, also depends on the water circuit, the balance of the ink circuit as well as the accuracy of the combined pressure. Each color group of the two-color machine has a waterway and inkway device. In order to facilitate the adjustment of water roller speed, each water roller is controlled by a frequency converter, and at the same time, the speed of the main motor also needs to be adjusted by a frequency converter. Therefore, in order to achieve multi-way speed regulation, we use the Mitsubishi 4D/A digital-to-analog converter, which will be given by the PLC side of the digital quantity, according to the corresponding algorithm, converted into 0 ~ 10V DC voltage output, well realized the multi-way speed regulation requirements.

CC-PCF901 51405047-175 In the printing process, plate adjustment is a relatively tedious process. Especially for multi-color machine, the accuracy of each group of plate alignment will have a great impact on the print. If the overprinting is not allowed, the print will be overlapped or unclear image. Generally speaking, the axial adjustment range of the printing plate is -2mm～+2mm, and the circumferential adjustment range is -1mm～+1mm. if you use manual plate adjustment, it will waste a lot of time and the accuracy is not high. In order to realize automatic plate making, we install potentiometer on the plate roller, through which the analog quantity will be transmitted to 4A/D, and after PLC processing, the rotation precision of the plate roller can be well controlled within the range of plate making.
