Mitsubishi PLC writes the holding circuit
There is a very common kind of circuit in Mitsubishi PLC - the persistence circuit. The insistence circuit means that when the external input switch is a button, it can be pressed through the insistence circuit to press the button to insist on the output, similar to the self-locking in the electrical diagram. Let's take Mitsubishi PLC as an example to write a sticking circuit.

Characteristics of servos and advantages of Mitsubishi servos
The servo system is an automatic control system that enables the output of the object's orientation, direction, and state to change with the arbitrary change of the input quantity (or given value). In the automatic control system, the system that can echo the control signal with a certain degree of accuracy is called the follow-up system, also known as the servo system.
