This property specifies the conversion factor between the user jerk units and the internal units [counts per msec3].
 | 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. |
Short form
<GROUP>.Jfac
Syntax
<GROUP>.JerkFactor = <expression>
?<GROUP>.JerkFactor
Availability
All versions
Type
Double
Range
Greater than zero
Default
1/6e10 (=1.667e-11). This value is suitable for working in units of position units per minute per second2.
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.
Examples
G1.Jfac = 1 / (60000 * 1000 * 1000) ‘work in per minute per second squared
G1.Jfac = 1 / (1000 * 1000 * 1000) ‘work in per second cubed
