描述

This property specifies the conversion factor between the user’s acceleration units and the internal units [counts per msec²]. The <element>.ACCELERATIONFACTOR must contain the conversion factor for both the position dimension and the time dimension.

类型

Double

取值范围

Greater than zero

默认

Axis = 71.5828
This value is suitable for working in units of RPM/second with resolver feedback.

Group = 65536/6e7 (=1.092e-3).
This value is suitable for working in units of position units per minute per second

使用范围

Configuration, Task or Terminal.

限制

Cannot be changed while axis is enabled or while axis is set up as a Master axis.

To set the value within a task, the axis must be attached to that task (using the ATTACH command).

例子

Axis
A1.Afac = A1.Pfac / (1000 * 1000)                  ‘Position units per second squared
A1.Afac = Xaxis.VelocityFactor / 1000         ‘Velocity units per second

Group
G1.Afac = 1 / (60000 * 1000) ‘work in per-minute-per-second
G1.Afac = 1 / (1000 * 1000) ‘work in per-second-squared
