官方故障排除步骤
Details The sensor signal was already ON when the tool measurement mode (TLM) signal was validated. The sensor signal turned ON when there was no axis mo vement after the tool measurement mode (TLM) signal was validated. The sensor signal turned ON at a position within 100 μ m from the final entry start position. Remedy Turn the tool measurement mode signal input OFF, and move the axis in a safe direction. Disabling the sensor signal al so clears the operation alarm. (Note) When the "tool length measurement 1" signal is disabled, the ax is can be moved in either direction. Pay attention to the movement direction.
