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.

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/(1000^3)
- Position units per second cubed
- Position units per second cubed
Xaxis.Jfac = Xaxis.AccelerationFactor / 1000
- Acceleration units per second
