With Spindle Feedback
If you have spindle feedback or a tachometer, you can use the shorter method to calibrate your spindle. Simply
find the values shown below.
Current Velocity
Use the velocity value found above from the
Motor Tuning and Setup
window.
Commanded RPM
Enter in a spindle speed as shown above. Then turn the spindle on.
Actual RPM
Record the actual speed either using a tachometer or another method of spindle feedback.
Now plug these values into this formula:
New Velocity
=
Current Velocity
*(
Commanded RPM
/
Actual RPM)
Your new velocity value should be fairly close to 1575. If not, check your calculation again.
With your new velocity calculation, go to the
Motor Tuning and Setup
window by selecting
Config
, then
Motor
Tuning
. Press the
Spindle
button and enter in your new velocity. Press
SAVE AXIS SETTINGS
before pressing
OK
.
Your spindle should now be calibrated.
Without Spindle Feedback
If you do not have a method to calculate your spindle speed, you can calibrate your spindle by using the
frequency of your variable frequency drive (VFD). However, you need to find the five different values as shown
below.
Current Velocity
Use the velocity value found above from the
Motor Tuning and Setup
window.
Pulley Max
Go to
Config
on the main menu bar, then select
