AXY:MC-Basic:axis.ACCELERATIONFACTOR

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

Short form

<axis>.Afac

Syntax

<axis>.AccelerationFactor = <expression>

?<axis>.AccelerationFactor

Availability

All versions

Type

Double

Range

Greater than zero

Default

65536/6e7 (=1.092e-3). This value is suitable for working in units of RPM/second with resolver feedback.

Scope

Configuration, Task or Terminal.

Limitations

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).

Examples

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

Xaxis.Afac = Xaxis.VelocityFactor / 1000         ‘Velocity units per second
