MC-Basic:element.ACCELERATIONFACTOR

Language:	English  • 中文（简体）‎

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.

Short form

<element>.Afac

Syntax

<element>.AccelerationFactor = <expression>

?<element>.AccelerationFactor

Availability

All versions

Type

Double

Range

Greater than zero

Default

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

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

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
