How to correctly use absolute positioning motion instructions to improve operating efficiency

Absolute positioning motion instructions are one of the common automation control technologies in modern factories. It utilizes precise positioning control to achieve precise movement of objects by specifying target locations. Correct use of absolute positioning motion instructions can not only improve operating efficiency, but also improve production quality and reduce costs. This article will introduce in detail how to use absolute positioning motion instructions correctly and give corresponding code examples.

First of all, the correct use of absolute positioning motion instructions requires a clear target position. Before using the absolute positioning instruction, the target position needs to be accurately input into the control system in advance. This can be determined through methods such as measurement, testing and simulation. Ensuring the accuracy of the target position is very important for the correct use of absolute positioning instructions, because if the target position is inaccurate, it will cause motion errors and reduce operating efficiency.

Secondly, the correct use of absolute positioning motion instructions requires reasonable setting of motion parameters. Motion parameters include speed, acceleration, deceleration, etc. When setting these parameters, they need to be adjusted according to the specific application scenario and the capabilities of the machine. Setting the speed too fast can cause overshoot and vibration, and setting the speed too slow can reduce operating efficiency. Reasonable acceleration and deceleration settings can improve operating efficiency by reducing movement time and machine load. The following is a sample code:

M44 P1000      ; 设置目标位置为1000mm
M45 V500       ; 设置速度为500mm/s
M46 A100       ; 设置加速度为100mm/s^2
M47 D100       ; 设置减速度为100mm/s^2
M48            ; 启动绝对定位运动

The M44 instruction in the code is used to set the target position to 1000mm, the M45 instruction is used to set the speed to 500mm/s, and the M46 instruction is used to set the acceleration to 100mm/s^2. The M47 command is used to set the deceleration to 100mm/s^2, and the M48 command is used to start absolute positioning motion.

Finally, the correct use of absolute positioning motion instructions requires reasonable motion control logic. In addition to setting the target position and motion parameters, it is also necessary to design the correct motion control logic according to specific operational requirements. For example, if circular motion is required, it can be achieved using loop structures and conditional judgment statements. The following is a sample code:

# 程序开始
    M44 P1000       ; 设置目标位置为1000mm
    M45 V500        ; 设置速度为500mm/s
    M46 A100        ; 设置加速度为100mm/s^2
    M47 D100        ; 设置减速度为100mm/s^2
    M48             ; 启动绝对定位运动

    # 等待运动完成
    M49
    # 进行其他操作
    ...

    # 继续运动
    M48
    ...

    # 结束程序
    M50

The M49 instruction in the code is used to wait for the movement to complete, and the M50 instruction is used to end the program. By properly setting the motion control logic, complex motion operations can be realized and operation efficiency improved.

To sum up, the correct use of absolute positioning motion instructions can improve operating efficiency, improve production quality and reduce costs. By clarifying the target position, reasonably setting motion parameters and motion control logic, and using corresponding code examples, readers can be helped to correctly use absolute positioning motion instructions so that they can play a greater role in automated control.
