Why can't the RDC8445S controller panel positioning function be used?

You check the following items, and your problems are usually caused by these reasons
1. The software does not set the graphic positioning position to: current position; But it was set as the mechanical origin or absolute coordinates
2. The positioning key on the operation panel is damaged, causing it to malfunction. It can be replaced with a new panel for testing
3. The control card has set the multi positioning point function. After setting the multi positioning point function, the positioning keys on the panel will not work, and the system will process according to the set positions of the multi positioning points. If you want to restore the function of the positioning key on the control panel, you need to disable the multi positioning point function in the menu of the control panel (this function is applicable to Ruida series controllers)

If there are no issues with the settings described by Howard, the problem may lie in the hardware. Try replacing the control panel with a new one to test and rule out the possibility of damage to the positioning buttons on the panel
