1. Introduction
This manual describes how to install the Centroid (Computer Numerical Control) system. It is
strongly recommended that you follow each step in order without skipping steps. The PC based
Centroid system provides to 8 axis closed loop servo interpolated motion, controlled by industry
standard G-Codes. The system is intended for CNC control of milling machines, routers, lathes,
flame, plasma, laser/water jet cutters, and other specialized applications. The Centroid system is
intended for use by competent installers, retro-fitters, and machine tool builders who want to do
their own installation. This installation manual is not intended for casual end users.
Before You Begin:
Installing your new Centroid CNC11 based GPIO4D Third Party Drive System is a straight forward
process if you follow the directions included here. Before getting started, please take the time to
familiarize yourself with the schematics, manuals and installation instructions.
While doing the installation, it is very important that you follow the instructions exactly. Doing the
installation incrementally and testing as you go will allow you to immediately isolate the cause of
any problems that you may run into. A troubleshooting procedure is included for each section of
the installation so that if you do run into any problems, you will be able to quickly isolate the cause
and correct it, if more information is needed please use the Centroid dealer support site at:
http://www.centroidcnc.com/dealersupport/index.php to review all schematics, tech bulletins and
other information you can use to set up your control.
If you run into a problem that you can not solve using the troubleshooting procedure or through the

3. Desk/Bench Top Connection & Software Install.
Now that you have all your kit all check out, it's time to do a desktop connection to test everything out before mounting
everything in your electrical cabinet. Before you install the software connect your power supply, GPIO4D, and your
MPU11 to your PC,as shown in Figure 3. You will need a RJ45 cable to connect your PC and MPU11 as shown in
Figure 4 and 5, (This cable is not included in your kit.).
Connect your RJ45 cable to the back of your PC. (Also known as Ethernet) This
is your commutation between your PC and MPU11.

7. Wiring Basic Sub-systems
7.1 Limit switch input wiring Limit switches on the GPIO4D MUST be a normally closed type
switch (contact closure), and proper wiring is show above. The GPIO4D does allow for use of 5, 1
or 4vdc inputs based on your sip resistor selection. The standard shipping configuration is 1 vdc
and is what we have shown above.
7. Limit switch PLC input testing Power up your system to test the limit switch and PLC input
wiring. Start the CNC11 software by double clicking on the CNC11 Mill icon on your desktop. After
the MPU11 has initialized, press F10 to continue to the main screen. Now, hold down the “alt” key
and press the “i” key at the same time to bring up the real-time I/O display.
The image to the right shows the limit switches,
inputs 1-6, in the upper left in the normally closed
and operational state.
Trip your limit switches individually and confirm that the display changes from green to red and
then back to green when you trip and release each switch that you have wired. Confirm that,
when none of the limits are tripped, ALL limit switch inputs (1-6) MUST be green. If they are not,
please check your limit switch wiring.

9. Wiring Subsystems
a) Lu e Pump Wiring We will start with wiring of the Lube pump sub circuit. The example we will
use is the standard 110vac Lube Pump.
LUBE PUMP SUBCIRCUIT
The typical lube pump circuit consists of two parts: The first part is the control of the lube pump itself which is
controlled by output sending 110VAC to the lube pump. The second part is the low lube alarm signal which
gets wired to input 9. The low lube signal tells the control to produce a “405 Low lube” alarm which inhibits the
control from starting a new job until the lube pump is refilled and the alarm is cleared.
When wiring your lube pump it is important to know which type of lube pump you have so that you configure it
correctly. Typically lube pumps come in one of 3 types:
1. The Mechanical Cam Actuated Lube Pump is based on a simple mechanical plunger riding on a clock motor
driven cam. The advantage of this type of lube pump is that it is reliable and it remembers where it was and
how much run time has been accumulated even between power cycles. So that you actually get lube ever 10
minutes for 5 seconds of machine use.
. Electronic Lube Pumps try to imitate the mechanical cam pumps but often forget where in sequence they
were when powered off. There are two types of Electronic lube pumps, “lube first” which pumps lube
immediately after power on. Which typically results in too much lube. The second type is “lube last”, this type
waits a set amount of time before lubing the machine. The problem with is type is on small jobs your machine
may never get any lube, therefore possible damaging the machine. To avoid this some people wire the lube
last type to get power all the time which then results in too much lube.
3. Direct controlled lube pumps are controlled by the control via the PLC program and the software. With this
type the lube pump is not responsible for the timing of the pump actuation. This method is the best for reliable
even lubing of your machine. Centroid Users see Tech Bulletin #171 and Parameter 179 in the operators
manual for further explanation.
