缩写

None

格式

<axis>.PositionBacklash = <double>

可用版本

4.5.33 and later

描述

向PCMD值添加位置反向值。 该值将被添加到运动的正方向（<axis>.VCMD > 0），而在相反方向上则使用该值乘以-1。在静止状态（VCMD = 0）时，使用前面的间隙值。

正负应用反向间隙值之间的差异将通过简单的alpha滤波器来实现平滑：PositionBacklashAlpha.

在位置反馈中没有补偿间隙位置值。 因此，在位置误差（PE）中将位置间隙应用到非零值将导致中相同的相反值，它将看起来像PE从未关闭。

类型

Double

取值范围

MIND ... MAXD

单位

Position user units

默认

0

使用范围

Task, Terminal

限制

Modal only

例子
