MODICON 140CHS11000 Quintessence 140 Series PLC Module

140CHS11000 In the process of feeding, plc compares the number of pulses received with the set value, and according to the comparison result, it drives the corresponding output point to control the output frequency of the frequency converter, so as to realize that the feeding speed slows down when it is close to the set value, so as to reduce the inertia of the system, and to achieve the purpose of precise positioning. In addition, today’s inverter technology has made great progress, so that the torque of the motor at low speeds is greatly improved, which also ensures the feasibility of low-speed advancement when feeding and positioning.

140CHS11000 for these necessary input points, the choice of fx1s-30mr plc, because the choice of human-computer interface, some other manual action, such as forward, backward, tool change, etc. are realized through the human-computer interface, do not need to take up the plc input points, thus for the choice of low-priced fx1s series plc has become possible, because fx1s This makes it possible to use the low-cost fx1s series plc because the maximum number of input points for the fx1s series plc is only 16. In addition, the high-speed counter of this series plc has the ability to process pulses with a frequency of up to 60 kHz, which is sufficient to meet the accuracy requirements of the paper cutter.

The 140CHS11000 encoder should be selected in accordance with two aspects, one is the highest pulse frequency received by the plc, and the other is the accuracy of the feed. We choose the encoder resolution is 500p/r (500 pulses per revolution per phase output). Through the verification, we can know that this resolution can meet the above two conditions. Parameters required for verification: the maximum speed of the motor is 1500 rpm (25 rpm), and the lead of the feed screw is 10mm/rev.
