How to realize position control? Method for realizing position control through cylinder control

1, the setting is simple, Y 1 is the forward (process) solenoid valve, Y2 is the reverse (return) solenoid valve, X 1 is the start switch, and X2 is the induction switch in the middle of the trip.

2. The 1 line is set to X 1 start, and the forward solenoid valve is preset to1hour (much longer than the actual working time). After the induction switch X2 is in place, the forward solenoid valve Y 1 is closed and the cylinder stops at the current position.

3. Line 2 is set to start the inductive switch X2. When the induction switch is in place, the forward solenoid valve Y 1 is closed and line 2 is started at the same time. Line 2 is provided with a delay timer of 1 sec. After the cylinder stays at this position for 1 s, the output timer works, Y2 starts the reverse operation, and Y2 closes after returning to the initial position for 2 seconds.

4. Above, the position control of the cylinder is completed.
