Official Troubleshooting Steps
Section: CNC alarm list Alarm group: Program/operation, background edit, communication (PS/BG/SR common alarm number) Original alarm number: 0175 An axis which cannot perform cylindrical interpolation was specified. More than one axis was specified in a G07.1 block. An attempt was made to cancel cylindrical interpolation for an axis that was not in the cylindrical interpolation mode. In cylindrical interpolation mode, to specify circular interpolation including a rotation axis (when bit 0 (ROT) of parameter No. 1006 is 1 and parameter No. 1260 is set), the value of rotation axis parameter No. 1022 must not be 0 but 5, 6, or 7 for parallel axis specification.
