The velocity factor of the external feedback is used to convert that value from counts per msec into physical units.
Short form
<axis>.VExtFac
Syntax
<axis>.VelocityExternalFactor = <expression>
?<axis>.VExtFac
Availability
All versions
Type
Double
Range
Greater than 0
Default
1
Scope
Configuration, Task or Terminal
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
To work in revs per second, the VFAC must be set as
Xaxis.VExtFac = 2000/1000
