The control starts up in Incremental jog mode. In order to jog the axes in continuous movement, you need to press the INCR/CONT key to switch from incremental to continuous jog mode.
The Machine Home position is fully X- (table right), Y+ (saddle out) and Z+ (head up). The rotary table does not move: home is wherever it sits when you home the rest of the machine.

The control starts up in Incremental jog mode. In order to jog the axes in continuous movement, you need to press the INCR/CONT key to switch from incremental to continuous jog mode. |
The work light
will come on automatically when the machine is powered up.
You can turn the light off and on by pressing the work light key on the jog panel.
You can insert and remove tools by hand when needed, using the tool clamp and unclamp pushbuttons on the front of the head.
The machine has a hydraulically shifted two-speed gearbox.
Gear shifting may be done manually with jog panel keys, or automatically with M functions, either in a CNC program or at the MDI prompt.
M42 |
High range (900-6000 RPM) |
 | |
| M41 | Low range (25-899 RPM) |
 | |
| M40 | Neutral (free spindle) |
| M49 | Shift to best range for programmed RPM |
M41 and M42 are not ordinarily needed. In normal programmed operation, the M3 and M4 codes will automatically shift to the appropriate range for the requested RPM, through the M49 code.
You can control spindle rotation speed and direction manually with jog panel keys, or automatically with program codes.
The spindle must be in Auto mode in order to use programmed M and S codes. The spindle must be in Manual mode in order to use the jog panel keys.
 |
Switch between Auto and Manual control modes. |
In manual mode, you can control operation and direction with these keys:
 |
Select spindle forward (CW) |
 |
Select spindle reverse (CCW) |
 |
Start spindle |
 |
Stop spindle |
 |
Orient and latch spindle |
In Auto mode, you can control operation and direction with these codes:
| M3 S__ | Select appropriate gear range and start spindle forward (CW tool) |
| M4 S__ | Select appropriate gear range and start spindle reverse (CCW tool) |
| M5 | Stop spindle |
| Snnn | Set speed to nnn RPM |
| M19 | Orient and latch spindle |
In either mode, you can further control speed with these keys:
 |
Increase speed |
 |
Set speed to 100% of programmed speed (Auto mode) or to half of maximum speed (Manual mode) |
 |
Decrease speed |
The A axis can be used as an indexer, or as a full fourth axis. In indexing operation, it can optionally be clamped and unclamped using the M10 and M11 codes:
| M10 | Clamp the rotary table |
| M11 | Unclamp the rotary table |
If you clamp the table with M10, you must remember to unclamp it with M11 before trying to move to another position.
The table will automatically unclamp when the program cycle ends.
To perform an automatic tool change use the M6 code, either in a program or at the MDI prompt.
E.g.
M6 T9
will put away whatever tool is in the spindle and will load tool #9.
You can also change tools using the F7/ATC option on the Setup, Offset Library, and Tool Library screens. On those screens, press F7/ATC; enter the tool number you wish to load; and press CYCLE START.
There are 200 tool entries available in the control's Tool and Offset Libraries. There are 30 usable stations ("bins") available in the machine's tool drum. You can assign bin numbers, from 1 to 30, to any tools in the Tool Library (F1/Setup, F2/Tool, F2/Tool Lib.).
For example, if you specify that tool 52 is in bin 12, then when your program calls for T52, the machine will load the tool from bin 12.
You can assign more than one tool to a bin.
You cannot change the bin assignment for the tool that is presently in the spindle. If this is necessary, put it away first by using M6 with a different tool number. Once the tool is back in the drum you can change its bin assignment (and move it by hand). If you wish, you can manually remove the tool from the spindle before telling the control to put it away in the drum and load a new tool. This will leave the bin empty.
As the machine runs and changes tools, it will always put the old tool back away in the bin it came from. Once set, a tool's bin assignment should not change until you choose to change it.
In a program, you can pre-stage tools using the M107 code. This allows the tool changer to rotate to the next tool in the job while the preceding tool is still cutting. E.g.
M107 T21
will rotate to tool #21 while the current tool is working.
You can also save a little time by inserting an M17 code at the end of a tool's final cut, just before the tool change. M17 will shut off the spindle and coolant, then start the spindle orientation process.
For example, using both M17 and M107:
M6 T1 M107 T2 M3 S2000 G0 X-1 Y0 Z.1 G43 H1 G1 ... ... G0 Z.1 M17 M6 T2 M107 T3 M3 S1400 G0 X0 Y-1 Z.1 G43 H2 G81 ... ... ... G80 M17 M6 T3 M3 S2500 G0 X0 Y0 Z.1 G43 H3 ... G49 M25
Intercon will include M17 automatically when it posts programs on the control. The above hints are useful when you are hand-writing G code programs or configuring offline CAD/CAM software.
When no tool change is in progress, you can
manually jog the tool drum forward using the ATC operator
panel below the drum.
This is a convenient way to load and unload tools in the drum.
Manual magazine rotation is permitted even when a program cycle is running, as long as no tool change or pre-stage is in progress.
If you have jogged the drum to a new position, the control will automatically bring it back to the correct location when it begins the next tool change.
If the control needs to perform an automatic tool change, and you have the
drum access door open (e.g. to replace a tool) the program will pause and
prompt you to close the door.
In rare cases it may be necessary to operate the tool changer components manually. You can do this with the ATC operator panel below the tool drum.
There are no safety interlocks when using the ATC operator panel. Before executing a step, double-check the function number and verify that there will be no collisions.
In order to exchange tools between the changer arm and the transfer arm, the head must be at the tool change position (G30 position). This is a short distance below machine home.
To put the Z axis at the G30 position, press F3 for the MDI prompt and enter:
G91 G30 Z0
If an error occurs which causes a tool change to be cancelled before it can complete, the control will assume that the old tool is still in place and the new tool is still back in the drum.
You can use the ATC operator panel to either back out of the tool change (putting the new tool away, as the control expects) or to finish the tool change. If the error occurred after the 180° rotation of the transfer arm, it will generally be easier to finish the change.
If you choose to finish the tool change, leaving the new tool in the spindle and the old tool in the drum, then you should manually exchange the tools so they are back where the control expects them to be (where they were before the tool change began). Tools in the drum can simply be lifted out and set in place. Tools in the spindle can be changed with the manual Unclamp and Clamp buttons on the head.
Optionally, you can use the F2/ATC Reset key on the Tool Library screen to re-teach the control the current tool-drum position; the tool in the spindle; and the drum location where the tool in the spindle should be put away.
If all of the tool changer components are in their parked-and-ready
positions, then the LED in the Aux11 key will be lit. You will see this
LED go out at the beginning of a tool change, as the transfer arm moves
down to pick up the new tool. The Aux11 LED will come back on when the
tool change has run to a successful completion: when the transfer arm
finally moves back up after returning the old tool to the drum.
If an error or fault occurs during a tool change, one or more of the components will be out of position, and the Aux11 LED will not light.
Use the ATC operator panel to return the components (changer arm, changer arm carriage, and transfer arm) to their parked positions. You should see the Aux11 LED light to indicate when everything is back in its ready position.
The following items should be done on a weekly basis:
The PLC program can report various error and fault conditions, in addition to those listed in the Centroid operator's manual.
You can use the PLC Diagnostic display on the console to view some of the Centroid PLC input, output and memory locations mentioned with these error and fault conditions. At the control's main screen, press Alt-I to activate the PLC Diagnostic display. Press Alt-I again to dismiss it.
Each page of the Diagnostic display shows four rows of red and green dots: the first row shows PLC inputs 1 through 80; the second row PLC outputs 1 through 80; the third row PLC memory bits 1 through 80; and the fourth row PLC program stages 1 through 80.
You can use the arrow keys to move a highlight box over any of these locations. The name of the highlighted location will be displayed in the center of the screen below the red and green dots.
For example, in the illustration above the highlight box is on Output #42: The dot below the 2, to the right of the superscript 4, on the second line.
Below the four rows of bit status information are ten numeric ("word") variable values, labeled W1 through W10. Some of these variables also hold useful status information, described with the error and fault conditions to follow.
There are multiple pages of Diagnostic data. With the Alt-I diagnostic display showing, you can use the F12 and F11 keys to scroll right and left. For example, pressing F12 once will shift to the page showing inputs and outputs 81 through 160, and word variables W11 through W20.
Most fault conditions must be cleared by pressing the Emergency Stop button. Fault conditions have 9000-series message numbers.
Non-fault Error conditions generally cancel the program cycle and stop the spindle and coolant, but do not then need to be explicitly reset. Non-fault Error conditions have 8000-series message numbers.
Warnings and informational messages have 5000-series and 2000-series message numbers. They do not cancel the cycle or require any action to reset.
If any type of error occurs during a tool change sequence, the PLC will encode the state of 21 different inputs and flags, as they were at the moment of the error, in variable W8.
If you encounter an ATC error and the cause it not immediately obvious, press Alt-i to view the PLC Diagnostic display, and write down the value shown for W08. This will help Tech Support identify the source of the problem.
During a jogging move either the MP7 spindle probe or the MP4 table probe was tripped. The machine stops in order to prevent damage to the probe.
The MP4 table probe may be prone to false trips from X and Y axis movement.
If this is a persistent problem, use the Aux2 key to disable the table probe
when you are not using it.
A tool change was requested, but the specified tool was not in one of the recognized bin numbers (1 - 30). Check the bin numbers listed in the Tool Library (F1/Setup, F2/Tool, F2/Tools).

The console arm is in a position where the table guards could potentially hit the console, and the X and Y axes are moving into the console arc.
Swing the console out in front of the machine, then press CYCLE START to resume movement.
Sensor PRS87 is located below the console arm pivot, and senses a cam which closes the sensor when the console is clear of any possible interference.
When PRS87 is closed, the LED in the Aux12 key will light to show
that the console is clear of possible interference.

The CNC program is attempting to start the spindle shortly after an automatic tool change, but there is no tool detected in the spindle. The program pauses until you either press CYCLE START to proceed, or you press CYCLE CANCEL to end the program.
This is to protect against damage in case the tool change sequence somehow missed or dropped the new tool. If it is your intent to run without a tool (e.g. in a dry run) then just press CYCLE START.
If this message appears as a false alarm (if there really is a tool in the spindle) then check the position of the rings and sensors at the top of the drawbar. The topmost sensor is PRS21. It should only close (sense) when the drawbar is higher than the normal tool-clamped position: a position it should only be able to reach if there is no tool present.
