LC Run Away
When attempting to move an axis by jogging or when running a file, one axis "takes off", usually resulting in a crash at the end of travel or a red box position error Ensure feedback in setup When axis is pushed by hand, the numbers in the Positional Display for that axis do not reflect the change in position. When the Motor cable swap procedure is performed, the same axis exhibits this problem.
The encoder feedback data is not reaching the controller.
The most common cause is a damaged encoder. Contact tech support to discuss having the encoder replaced. Sometimes cables can be damaged and cause this problem. The potential cables for this problem are the cable between the PC and the Controller box, and the rectangular cable between the motor and the Controller box
