反向间隙补偿

定义

修正传动间隙带来的误差。

以前置元数据中的定义作为统一语义，并在装夹、加工与检验环节保持一致。

公式/规则

• 反向间隙补偿应尽量接近轴向实测反向误差，而不是随意放大。
• 丝杠或伺服维护后要重新测量，因为补偿值会随机械状态变化。

典型范围

• Use compensation only within the measured machine condition; excessive values can create overshoot or unstable reversal behavior.
• Reversal error should be checked warm and under realistic axis loading if the machine is sensitive.

现场场景

• Check reversal error on a circular interpolation test before changing backlash settings machine-wide.
• Verify axis response after compensation updates on both short travel moves and long positioning moves.

常见错误/排障

• If reversal marks remain after compensation, re-measure the axis and inspect screw, nut, and coupling condition.
• If motion overshoots after a compensation change, reduce the value and verify servo tuning before production resumes.
