Motion-related inquiries

When the J and L codes are output from an external program, the robot joints it interprets are different from the program's positioning. Is there a way to resolve this? In the CAM program, the 4th and 6th axes are set to 0 and processed, but when I load the program from AR4 and operate it, the 4th and 6th axes behave unpredictably. When I program it using the R mechanical joints, it works normally. However, when I operate it using the R joint coordinates, the acceleration and deceleration are completely different. Is there a way to resolve this? Even when I measure the position using J and L movements in AR4 and operate it, the joints rotate 180 degrees, causing the robot to catch a rat.
