If you press any of the bridge stop buttons (the four red buttons on the sides of the moving bridge) during a program cycle, the control will activate Feed Hold. You must clear the bridge stop button and then press CYCLE START to cancel Feed Hold and resume movement.
Feed Hold only applies in an automatic cycle. The bridge stop buttons will not stop manual jogging moves.
If you press Emergency Stop, or a fault occurs which causes the Emergency
Stop contactors to open, you must either clear the fault and release E-stop
within about four seconds, or you must wait approximately 20 seconds for
the spindle drive to discharge before you can resume normal operation.
In this situation, you can release Emergency Stop sooner, but the message
"2110 Waiting for Inverter to Discharge..." will be displayed until the
required time has passed.
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.
To put away the current tool without loading a new one, use the M36 code, either in a program or at the MDI prompt.
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. However, only tools 1-10 may be used with the automatic tool changer.
As the machine runs and changes tools, it will always put away the old tool in its original carousel bin, before rotating to the new tool.
Use coordinate system #1 (E1, or G54) for the router spindle. Use tool height offsets (G43 Hnn) to adjust for varying lengths of the tools in the carousel.
For example:
M6 T1 M3 S12000 G43 H1 G0 X-1 Y0 Z.1 G1 ... ... G0 Z.1 G49 H0 M6 T2 M3 S14000 G43 H2 G0 X0 Y-1 Z.1 G81 ... ... ... G80 G49 H0 M6 T3 M3 S2500 G43 H3 G0 X0 Y0 Z.1 ... G49 H0 M36 G53 Z0
The control provides the following custom M functions, in addition to the standard codes listed in the Centroid manual.

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 Aux13 key for 1 second. The Aux13 LED will light to indicate that Maintenance Mode is active.
In Maintenance Mode you can use the Aux10, Aux11 and Aux12 keys to directly operate the tool changer components.
 |
Unclamp tool (momentary) |
 |
Move tool changer down or up (toggle) |
 |
Move tool changer in or out (toggle) |
For example, if a fault occurs with the carousel in and up, with a tool clamped in the spindle, you could:
Simply press Aux12 to retract the carousel (leaving the tool in the spindle), or
In Maintenance Mode, you can also use the blank gray jog keys (in the left-most column, to the left of the Y axis keys) to jog the tool carousel (A axis). The control will not automatically stop A on a whole number position; it is up to you to line up the carousel with the router spindle.
When you are done using the Maintenance Mode controls, press and hold Aux13 for one second again to cancel Maintenance Mode. The Aux13 LED should go out, indicating a return to normal operation.
You cannot run automatic program cycles (including MDI mode) with Maintenance Mode active.
The control keeps track of the "put-back" location for the tool in the spindle using Machine Parameter 171. See Chapter 14 of the Centroid M-Series Operator's Manual for a summary of Machine Parameters.
If you need to override or change the put-back position, you can store a new value in Parameter 171 using MDI mode or the Machine Parameters screen. For example, to set the put-back position to carousel position 5:
In the next tool change, the tool in the spindle would then be put away in position 5.
To indicate that the spindle is empty (there is no tool to put away) set Parameter 171 to zero.
The following parameters are set to provide at-speed and running signals on the auxiliary relay outputs:
| Parameter | Value | Meaning |
| TAB3 -> OC1 | +2 | Close terminal 21 to 19 when at commanded speed |
| TAB3 -> OC2 | +3 | Close terminal 22 to 19 when stopped |
See the Berges ACM-D2 Manual for detailed information on these and other spindle drive parameters.
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 console to view some of the Centroid PLC input and memory locations mentioned with these fault and error 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 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).

During an automatic tool change, the tool carousel failed to slide all the way in (towards the spindle) in the allowed time.
This is typically due to an obstruction in the way (for example, attempting to put a tool away in a carousel pocket that already has another tool in it); or to carousel misalignment (not rotated to line up with a tool pocket); or to lack of air pressure to the cylinder.
Use the Maintenance Mode controls to retract the carousel back to its normal position. Remove any unwanted tool from the spindle or carousel. Check that the position shown for the A axis matches the actual carousel position.
