Tool carousel positions are numbered 1 through 12. Tools and offsets are numbered 1 through 199. Any tool number can be used in any carousel position. Tools are assigned to carousel positions ("bins") in the Tool Library.
You can insert and remove tools by hand when needed, using the tool release pushbutton on the front of the head.
In a program cycle, tool changing is automatic, with the M6 code and T number in your CNC programs.
In manual and setup operations, you can change tools automatically by using the ATC function key (F7 on the Setup menu and in the Tool Offset Library; or by entering an M6 tool-change command at the MDI prompt (F3 on the main menu).

In rare cases it may be necessary to operate the tool changer components manually. You can do this with the Aux keys on the jog panel, but only in "Maintenance Mode". To activate Maintenance Mode, press and hold the Aux12 key on the jog panel for one second. The light in the Aux key will come on, indicating that Maintenance Mode is active. To cancel Maintenance Mode, press the Aux14 key and hold for one second again.
Aux12 is the blank gray key below the Aux9 or "Tool Index +" key.
You must cancel Maintenance Mode before you can run normal program cycles.
There are no safety interlocks in Maintenance Mode. You must be careful, among other things, to:
In Maintenance Mode, the following Auxiliary keys on the jog panel have special functions:
|
Spindle Orient/Cancel | |
Tool Unclamp/Clamp | ||
|
Carousel Out (Retract) | |
Carousel In (Advance) | ||

The PLC program can generate a number of system-specific error and fault messages, 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 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.
Messages with 9000-series message numbers are Faults. After resolving the problem, you must press and release the Emergency Stop button to clear a Fault.
Messages with 8000-series message numbers are Errors. Errors will cancel the program cycle and stop the spindle and coolant, but they do not then need to be explicitly reset.
Messages with 5000-series and 2000-series message numbers are Warnings and Informational Messages. They do not cancel the cycle or require any action to reset.
The control detected an internal error in processing the PLC logic program.
Report this error to your dealer, along with the values from W14 and W15. Also report what function the machine was performing when the fault occurred.
You must shut down and cycle the power to clear this fault.

The MPU11 motion controller detected loss of fiber optic communication from the RTK3 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).
Verify that six green status LEDs on the RTK3 bottom board are lit. If no LEDs are lit on the RTK3 unit, check its logic power, which is derived from the 120VAC input to the top board.
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 start an automatic program cycle, but Maintenance Mode is still active.
Press and hold the Aux12 key for one second, until the Aux12 LED goes out.
During tool carousel rotation, the tool counter input changed state earlier than normal motor rotation would allow. This may indicate that a false signal due to electrical noise.
The "(1)" version of the message is used when the early change happens while moving out of one position, into transition.
Use the Tool Index Plus or Minus auxiliary keys to move the carousel the rest of the way into a tool position, then press Alt-K to display the system's current carousel position, and compare it with the actual carousel position.
If the system's position does not match the actual position, then use the ATC Reset key on the Tool Library screen to correct it.
During an automatic tool change, the carousel did not rotate out of the current position in the allowed time.
If this message appears without any movement of the carousel, then it is either a power problem (unable to get power to the carousel motor) or a physical obstruction.
If this message appears while the carousel has been rotating, then it is probably an issue with the tool counter sensor.
