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+ (cross slide up) and Z+ (carriage right).

The machine has the following custom M functions, in addition to the standard functions listed in the Centroid operator's manual.
| M10 | Close chuck | ||
| M11 | Open chuck | ||
| M12 | Extend Tailstock Quill | ||
| M13 | Retract Tailstock Quill | ||
| M21 | Fetch tailstock body and place it near part zero | ||
| M22 | Put away tailstock body near end of bed | ||
| M31 | Chip conveyer forward | ||
| M32 | Chip conveyer reverse | ||
| M33 | Chip conveyer off | ||
| M35 | Latch tailstock body to carriage, unlock from ways | ||
| M36 | Unlatch tailstock body from carriage, lock to ways | ||
| M41 | Shift to low gear (0 - 1250 RPM) | ||
| M42 | Shift to high gear (0 - 4190 RPM) |
The M21 code will retrieve the tailstock from wherever it was last placed (usually its parked position near the end of the bed, but possibly another in-use location) and place it near the current part zero location.
M21 will use the Z offset for Tool 99, from the Tool Offsets library, to align the tailstock. A larger (more positive) value in offset 99 will place the tailstock farther right. A smaller (or more negative) value in offset 99 will place the tailstock farther left.
The M22 code will retrieve the tailstock from wherever it was last placed, and return it to its parked position near the end of the bed.
M21 and M22 use the following Machine Parameter values:
| Parameter | Meaning | Default Value |
|---|---|---|
| 910 | Parked location, measured from Z axis machine zero | -0.500 |
| 911 | Half of sensor window width | 0.060 |
| 912 | Starting search distance for sensor | 0.200 |
| 913 | Part location for M21 placement | 0.000 |
| 914 | Slow search feedrate | 10.0 |
| 915 | Drag feedrate | 50.0 |
M21 and M22 also use variable #159 to store the location where the tailstock was last placed. This is the Z axis position, in Machine Coordinates.
If for some reason the tailstock is not where it was expected, or the value of variable #159 has been lost, then M21 or M22 may fail to pick up the tailstock.
In that case, you should jog the carriage to the tailstock, stopping where the connection-position sensor (INP8) opens; then note the Z position in machine coordinates (press Alt-D to show machine coordinates on the DRO); then store that value in variable #159 (e.g. by using the MDI prompt to enter a command such as "#159 = -12.345").
In normal operation, the Aux keys on the operator panel have the following functions:
 |
LED indicates tool setter tripped |  |
LED indicates carriage aligned for tailstock connection |  |
Unclamp/Clamp Tool |
 |
Shift headstock to high gear range |  |
Work Light On/Off |  |
Index Turret Plus |
 |
Shift headstock to low gear range |  |
Maintenance Mode On/Off (hold for 1s) |
 |
Index Turret Minus |
 |
Latch/Unlatch Tailstock Base |  |
Extend Tailstock Quill |  |
Retract Tailstock Quill |
 |
Jog Conveyor Reverse |  |
Stop Conveyor |  |
Start Conveyor Forward |
In rare cases it may be necessary to operate the tool changer components manually. You can do this using "Maintenance Mode".
To activate Maintenance Mode, press and hold the Maint. Mode key for one second. The Maint. Mode LED will light to indicate that Maintenance Mode is active.
In Maintenance Mode you can use the other Aux keys to directly operate some tool changer components.

Be sure to cancel Maintenance Mode when you are done. You cannot run
automatic program cycles with Maintenance Mode active. You can, however, use
the MDI prompt in Maintenance Mode.
The PLC program can generate various fault messages, in addition to those listed in the Centroid operator's manual.
You can use the PLC Diagnostic display on the computer to view some of the Centroid PLC input and memory locations mentioned with these fault conditions. At the control's main screen, press Alt-I to activate the PLC Diagnostic display. Press Alt-I again to dismiss it.
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 at the bottom center.
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 fault conditions to follow.
There are multiple pages of PLC Diagnostic information. You can page sideways using the F12 and F11 keys. For example, pressing F12 once will scroll to the page showing INP81 - INP160, W11-W20, etc..
Most fault conditions must be cleared by pressing and releasing the Emergency Stop button.
The MPU11 motion controller detected loss of fiber optic communication from the GPIO4D interface unit.
Check the optical fibers. Verify that they have not been bent, kinked, or pulled loose from their sockets. Verify that they are both plugged into the correct sockets (1 to 1 and 3 to 3, on both boards).
The GPIO4D interface unit reported back to the MPU11 motion controller a loss of fiber optic communication from the MPU11. This indicates that Fiber 3 is functioning normally, but Fiber 1 may have problems.
Check the optical fibers. Verify that they have not been bent, kinked, or pulled loose from their sockets. Verify that they are both plugged into the correct sockets (1 to 1 and 3 to 3, on both boards).
One or more of the Yaskawa servo drives is reporting a fault condition.
Check the LED displays on the axis drives themselves for a fault code.
Press and release Emergency Stop to clear the fault.
The spindle drive unit is reporting a fault condition.
Check the LED display on the spindle drive itself for a fault code.
Press and release Emergency Stop to clear the fault.

You attempted to run a program cycle, but the turret tool clamp is still open.
Press the Tool Release key to release the solenoid and close the clamp, then start your program cycle again.
You attempted to run a program cycle, but Maintenance Mode is still active.
Press and hold the Maint. Mode key for one second to turn Maintenance Mode off, then start your program cycle again.
You requested a turret change to an invalid position. This is probably because the tool you requested is not assigned to a turret position, or is assigned to a position greater than 10.
Check the part program and tool library settings.

During an automatic tool change, the turret failed to reach the position immediately prior to the target position, within four seconds.
If this occurs with no turret rotation, check for mechanical or hydraulic failure.
If this occurs with continuous turret rotation, check turret encoder feedback.
The PLC will only accept the position code if strobe 2 is on.
The PLC will only stop rotation on an off-to-on transition of strobe 3, while the most recent tool position was the one immediately prior to the target position.

After completion of an automatic tool change, the turret position was not the expected target position. This may be due to spurious signals from the turret position encoder (causing a premature stop), or to a delay in stopping rotation and locking down (causing an overshoot by one or more positions).
Check rotation and stop timing and function, and check signals from the turret position encoder.

The PLCADD1616 expansion board has failed to communicate properly with the GPIO4D board.
Check the gray PLC expansion cable that connects the PLCADD1616 board to the header near the top edge of the GPIO4D board. Check for green 5V power and "PLC OK" LED indicators on the PLCADD1616 board.
The PLC program requested display of an error message, but provided an invalid message code. Notify your dealer.
The PLC program can also generate the following non-error messages, in addition to those listed in the Centroid operator's manual.
A previous PLC fiber communication fault (9022 or 9023) has been fixed and cleared.
You pressed a keyboard shortcut key for jogging the machine or starting a cycle, but those shortcuts have been disabled on this control.
A previous fault condition has been cleared by pressing Emergency Stop.
