1. A scanning cycle is divided into input sampling, program fulfillment, and output rewriting.
2. Each scan process. The convergence samples the input signal. The convergence rewrites the output signal.
3. The content of the component image register changes with the performance of the program.
4. The length of the scanning cycle is determined by three items. (1) The speed at which the CPU executes the instruction, (2) The time at which the instruction itself is possessed, and (3) the number of instructions
5. Due to the selection of aggregate sampling. The way in which the output is assembled. There is input/output lag, i.e., delayed input/output responses.
6. Enter the rewrite process. When the input port is closed, there is a new condition on the input side during the fulfillment phase of the program, and the new condition cannot be read in. The new status is read only when the program performs the next scan.

The working principle of the servo motor of the Mitsubishi CNC system
1. The servo mainly relies on the pulse to position, basically it can be understood in this way, the Mitsubishi CNC system maintenance servo motor receives a pulse, and it will rotate the angle corresponding to the pulse, so as to achieve displacement, because the servo motor itself has the function of sending out pulses, so the servo motor ...

Mitsubishi inverter overload fault judgment method
1. Check whether the three-phase electricity of the motor is balanced
(1) If the three-phase voltage of the motor is unbalanced, then check whether the three-phase voltage at the output end of the Mitsubishi inverter is balanced.
(2) If the three-phase voltage of the Mitsubishi inverter is also unbalanced, the problem is inside the Mitsubishi inverter, and it should be investigated.

Mitsubishi FX3u interrupts the location command
The main effect of aborting the positioning instruction is that in some machine tools, when we give the abort signal and can walk to the distance we set, for example, if the mechanical structure needs to use the sensor to determine the position to go, you can use the abort positioning instruction to do, when the induction gives the abort.

The difference between the measurement of ordinary motors and inverter motors - Mitsubishi
1. The actual output waveform of the inverter is PWM wave, which contains carrier signals in addition to the fundamental wave. The carrier signal frequency is much higher than that of the fundamental wave, and it is a square wave signal, which contains a lot of higher harmonics, and the test system requires a higher sampling frequency and bandwidth.
