This property specifies the conversion factor between user jerk units and the internal units [counts per ms3]. The axis JERKFACTOR must contain the conversion factor for both the position dimension and the time dimension.

Short form

<axis>.Jfac

Syntax

<axis>.JerkFactor = <expression>
?<axis>.JerkFactor

Availability

All versions

Type

Double

Range

Greater than zero

Default

65536/6e10. This value is suitable for working in units of rpm/s2 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).
  • JERKFACTOR is in effect only when the SMOOTHFACTOR is set to -1. Otherwise, JERKFACTOR is always set to ACCELERATIONFACTOR/1000.

Examples

A1.Jfac = A1.Pfac/(10003)

Position units per second3

Xaxis.Jfac = Xaxis.AccelerationFactor / 1000

Acceleration units per second
