Testing the analog output for the spindle: The Oak provides a 0 to +10VDC analog output to provide programmable spindle
speed control using a VFD (variable frequency drive). The default maximum spindle speed specified in the Control Configuration
is 3000rpm. This configures the control to scale the 0 to +10VDC from 0-3000rpm. A spindle speed command of S1500 will
therefore 5VDC, a command of S1000 will 3.33VDC and so on.
1. Set a digital voltage meter to VDC
2. Connect the seven pin terminal block into connector H9
3. Insert the digital voltage meter leads into H9 as shown in Figure 4.2.4. Tighten down the screw terminals to firmly grip the
probes.
4. With spindlebenchtest.cnc loaded, press Cycle start (alt-s) to begin. The following screen will be displayed: (You may have to
press Cycle start twice)
5. Enter the voltage readings as pictured, and press Cycle Start to continue. Spindlebenchtest.cnc will throw an error if the
spindle does not output as expected. Continue to press cycle start as requested until the program is finished. The program will exit
and the status window will say “
Job finished ” after a successful completion.
