|DESCRIPTION= 该属性指定用户加加速度单位与内部单位[counts per msec³]之间的转换因子。

	NOTE
	In using JERKFACTOR for the group, the position units are taken from the POSITIONFACTOR of the axes within the group. The position units must not be specified in the group’s JERKFACTOR.

	NOTE
	In using JERKFACTOR for the axis, The axis JERKFACTOR must contain the conversion factor for both the position dimension and the time dimension.

轴JERKFACTOR必须包含位置维度和时间维度的转换因子。 |TYPE= Double

|RANGE= Greater than zero

|UNITS=

|DEFAULT= Group - 1/6e10 (=1.667e-11). This value is suitable for working in units of position units per minute per second².
Axis - 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 group must be attached to that task (using the ATTACH command).

JERKFACTOR is in effect only when the SMOOTHFACTOR is set to -1. Then, JERKFACTOR is always set to ACCELERATIONFACTOR/1000.

|EXAMPLE= Axis
A1.Jfac = A1.Pfac/(1000³)         ‘Position units per second³

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

G1.Jfac = 1 / (1000 * 1000 * 1000)            ‘work in per second cubed
