140CPS11420 sends the required number of pulses to c235 through calculation, regardless of whether the feeding mechanism is forward or backward c235 to subtract the counting, and at the same time compares the value in c235, and according to the comparison result, drives the corresponding output point to the frequency converter for the control of the output frequency to realize that the speed of the feeding slows down when it is close to the set value, so that it can reach the precise positioning.

140CPS11420 has inertia and time hysteresis, so the time for the inverter to stop output is not when the count value in c235 is reduced to 0, but let c235 and a data register d130 compare, when the value in c235 is reduced to the set value in d130 plc control inverter to stop output. d130 value can be modified and set by the human-computer interface. The value of d130 can be modified and set through the human-machine interface, and the value can be modified during debugging to achieve the purpose of accurate positioning.

140CPS11420 Decimal point position problem when setting parameters. In practice, when setting the position, we need to be accurate to 0.1mm. this problem is often encountered in some microcontroller systems, the common way to deal with it is to increase an order of magnitude, that is, when setting the data, the HMI uses 1 instead of 0.1mm, 10 instead of 1mm. however, when we deal with this problem, through the hmi setting of the data and plc programming, we achieve the effect of WYSIWYG! The main thing in hmi is to set the format of the value.
