Figure 10 Spindle Buttons 
Note: If you don’t have the MachMotion screen set, turn on the spindle by pressing the button Spindle CW F5. 
When the button is flashing, the spindle should be on. 
 
Figure 11 Spindle Speed 
You can also control the spindle by using M-codes. As a reference use the table below. 
 
Test your spindle by commanding it to go half of the pulley’s maximum speed. If it is working correctly, your VFD 
will be running at close to half of the maximum frequency. Next command it to move the pulley’s maximum 
speed. Your VFD should now be running at the maximum frequency. If the frequency is very far off, check your 
calculations and make sure that the VFD was programmed correctly. If it still is not correct, you may have to 
calibrate your spindle.  
If your VFD is not turning on or if it has a fault, see the trouble shooting section below.
