STOP: Before wiring up the spindle make sure that the analog output was tested as directed in Section 4.1.9.
There are two methods of wiring a spindle:
•
Reversing Contactors: (logic connections shown in Figure 5.8.2, power connections in 5.8.3)
The 3 phase is connected to mechanically interlocked reversing contactors, controlled by outputs 7 and 8 on the Oak
board.
•
Variable Frequency Drive (VFD): (shown in Figure 5.8.1)
The terms “inverter”, “AC Drive”, and “VFD” (Variable Frequency Drive) can all refer to the spindle controller. Centroid has
Technical Bulletins for the following drives:

The max and min spindle speed set up in Section 4.1.3 as well as the spindle analog range need to match the inverter settings. If
this is different than 3000 rpm and 0 to +10 VDC, they need to be changed.
With the default PLC program, several of the I/O are used with a spindle:
Oak Input/Output Function
Input 10 Fault input from spindle controller
Output 5 Fault reset to spindle controller
Output 7 Fault output to spindle controller
Output 8 Spindle direction
Output 10 Cooling fan
Always refer to the schematic that came with the system.
In the example below the thermal overload protector is wired directly to the spindle fault. If your spindle controller has a fault
condition it should be wired in series with the thermal overload protector.
All contactors need snubbers. Centroid recommends using the Quencharc snubber (Centroid PART# 1819) on the coil of the
contactor. This reduces electrical noise when the spindle is turned off and on.
Enabling Spindle Fault Inputs:
1. Power up your system.
2. Start CNC12 and press F10 to continue to the main screen.
3. In the main menu press alt + I to bring up the real time I/O display.
4. Navigate to Input 10.
5. Press the ctrl-alt-i keys to remove any bars over the input.
