官方故障排除步驟
[Cause of error] The FK sequence is not complete at its program end. You will have to program additional data or NC blocks. [Error correction] * Add FK blocks as the end or edit them. * Add the missing data or NC blocks within the program. Note: - In each block, program the data that do not change. (Nonprogrammed data are treated as unknown.) - If the first block of an FK contour is an FCT or FLT block, you must program at least two NC blocks with the gray path function keys to fully define the direction of contour approach. An FK contour must not be programmed immediately after an LBL command
