官方故障排除步骤
Section: CNC alarm list Alarm group: Program/operation, background edit, communication (PS/BG/SR common alarm number) Original alarm number: 0090 1) The reference position return cannot be performed normally because the reference position return start point is too close to the referenc e position or the speed is too slow. Separate the start point far enough from the reference position, or specify a sufficiently fast speed for reference position return. 2) An attempt was made to set the zero position for the absolute position detector by return to the reference position when it was impossible to set the zero point. Rotate the motor manually at least one turn, and set the zero position of the absolute position detector after turning the CNC and servo amplifier off and then on again.
