Load Feedback Capability
负载反馈是实际燃油齿条位置与作业条件下最大可利用的燃油齿条行程之比。 此功能标示在该作业条件可利用的燃油齿条行程(功率)。 当燃油齿条的实际位置等于燃油极限值时，即标示 100% 的反馈值。 在低怠速无负载时，标示 0 反馈值。
表 1 显示用于计算负载反馈信号的等式。

负载反馈信号 (Y) 额定负载百分比。 (X) 发动机转速。 (1) 燃油齿条最大行程。 (2) 齿条实际行程。 | |
燃油齿条实际位置、燃油齿条最大位置和反馈信号均为瞬时值。 信息通过 CAT 数据链路传输。 采用 0 - 200 mA 的信号。 使用户可以将数据提供给控制系统。
