Figure 14 Max Pulley Speed
Your current pulley will be selected. Your
Max Speed
value is your pulley max needed for the spindle calibration.
Max VFD Hz
The maximum motor frequency is your Max VFD Hz (assuming your VFD is set up as shown above).
Commanded RPM
Enter in a spindle speed as shown above. Then turn the spindle on.
Actual Hz
Your VFD should display the current frequency in Hz, which is the Actual Hz value.
With the above information, you are ready to calculate your new velocity. Use the formula below:
New Velocity
=
Current Velocity
*(
Max VFD Hz *Commanded RPM
/
Pulley Max
)/
Actual Hz
.
Your new velocity value should be fairly close to 1575. If not, check your calculation again.
Now 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.
