The velocity factor of the external feedback is used to convert that value from counts per millisecond into physical units.
Short form

Limitations
Cannot be changed while axis is enabled or while axis is set up as a master axis.
Examples
If the feedback resolution is 2000 counts, and you want to work in RPM, the VFAC is set as:
- Xaxis.vExtFac = 2000/60000
- Xaxis.vExtFac = 2000/60000
To work in revolutions per second, the VFAC must be set as:
- Xaxis.VExtFac = 2000/1000
