MODICON 140AMM09000 Quintessence 140 Series PLC Modules

The most basic action accomplished by the 140AMM09000 is to bring the material to be cut to a specified position and then cut it. The core of its control is a single-axis positioning control. My company introduced a European company’s two paper-cutting equipment, the implementation of its propulsion positioning system is the use of microcontroller control, when receiving the encoder’s pulse signal reaches the set value, the microcontroller system output signals, disconnect the contactor of the feed motor, while the clutch separation of the electromagnetic clutch brake, the brake brakes the inertia of the propulsion system, so as to realize the precise positioning. Due to the aging of the equipment’s microcontroller control system, resulting in inaccurate positioning, paper cutting action disorder, can not be normal production.

The control system is an early product, there is no suitable accessories can be replaced, can only take this path of transformation. At present, the domestic paper-cutting equipment feeding and positioning system transformation there are two main ways, one is the use of microcontroller combined with frequency converter to achieve, one is the use of microcontroller combined with servo system to achieve, but the cost of these two transformation programs are more than 20,000 yuan. And microcontroller system is designed by the professional development company, conservative technology, once the failure can only be handed over to restore the company’s maintenance or replacement, maintenance cycle is long and high cost, is not conducive to the transformation of the maintenance and use of equipment!

140AMM09000 has a high-speed counter function, without the need to increase the special function unit can handle the frequency up to dozens or hundreds of khz pulse signal. Paper cutter to feed the system’s accuracy and response speed requirements are not very high, can be calculated through the paper cutter feeding system related parameters, a reasonable choice of encoder, so that the pulse frequency that can be processed in the plc within the scope of the feed can also meet the accuracy requirements.
