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. |
Turret positions are numbered 1 through 8. Tool offsets are numbered 1 through 99. Any offset number can be used with any turret position. However, for simplicity you should use offsets 1 through 8 with positions 1 through 8. Higher-numbered offsets may be used for additional tools (gang-style) in each turret position.
I recommend measuring tool X offsets relative to turret centerline, and Z offsets relative to the turret face.
The procedure for this may be found at
http://www.cncsnw.com/OLEL.htm,
as "Method 1a".
Turret Controls
|
When no program cycle is active, you can index to the turret using the TURRET INDEX key on the operator panel. Press the key once to index to the next position. Press and hold the key to index multiple positions. |
In a program cycle, turret indexing is automatic, based on the first two digits of the four-digit tool number.
In manual and setup operations, you can also index the turret automatically
by using the ATC function key (F7 on the Setup menu, or F3 on the Tool Offset
screen; or by entering a tool-change command at the MDI prompt (F3 on the
main menu).
Collet Controls
In manual operation, use the "COLLET OPEN" and "COLLET CLOSE" buttons on the apron panel, or the similarly-named keys on the hand pendant, to open and close the collet.
In automatic operation (e.g. with a Bar Feed) use the following M codes to open and close the collet:
| M11 | Open Collet |
| M10 | Close Collet |
The parts catcher can be operated with automatic M functions or via the operator panel, as follows:
| M29 | Extend Parts Catcher |
| M28 | Retract Parts Catcher |
 | Extend/Retract Parts Catcher |
In normal operation, the Auxiliary keys on the jog panel have the following functions:
 |
Work Light On/Off |
 |
Optional Stops Mode |  |
No function |
|
Extend/Retract Parts Catcher |
 |
No function |  |

| Aux13 | No function | Aux14 | Maintenance Mode On/Off |
| M0 | Stop (wait for Cycle Start) |
| M1 | Optional Stop (wait for Cycle Start) |
| M2 | Program Restart (with wait for Cycle Start) |
| M3 | Spindle CW / Forward |
| M4 | Spindle CCW / Reverse |
| M5 | Spindle Stop |
| M8 | Flood Coolant |
| M9 | Coolant Off |
| M10 | Close Collet |
| M11 | Open Collet |
| M13 | Spindle CW and Flood Coolant On |
| M14 | Spindle CCW and Flood Coolant On |
| M26 | Set Axis Home (only used in machine homing macro) |
| M28 | Retract Part Catcher |
| M29 | Extend Part Catcher |
M functions M91 and above are used internally in custom macro programs, but are generally not used directly in user machining programs.
See Chapter 12 of the Centroid T-Series Operator's Manual for descriptions
of the higher-numbered M functions.
Emergency and Maintenance Operation
In rare cases it may be necessary to operate the turret 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 Aux14 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.
Aux13 and Aux14 are the blank blue keys to the right of the Coolant control keys.
You must cancel Maintenance Mode before you can run normal program cycles.
In Maintenance Mode, the control cabinet is unlatched, and may be opened even with the main power still on. Only qualified electrical maintenance personnel should access the control cabinet while power is on.
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:
|
Turret Index | |
Turret Stop | ||
| (Aux11) | Retract Lockpin | (Aux12) | Extend Lockpin | ||
| (Aux14) | Maintenance Mode On/Off |
The PLC program can generate the following 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 24VDC supply which powers PLC inputs and turret solenoids has dropped out. This could be due to failure of the power supply itself, or due to a short-circuit somewhere in one of its loads (e.g. between the +24VDC wire to one of the machine switches or sensors, and the corresponding 0VDC wire or chassis ground).
Check PS2 for a green status indication. If none, try removing +24VDC connections (generally wires numbered 401) until PS2 comes back on line. This should allow you to isolate the circuit or device responsible for the short.
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 Aux14 key for one second, until the Aux14 LED goes out.
The part program requested a turret position other than T1 through T8.
Check the Tool Library in Intercon to verify that the Tool Location for each tool in your program is set to a valid turret position.
Note that to cancel tool offsets at the end of a CNC G code program, you must repeat the active turret position, changing only the offset portion to zero. For example "T0113" to "T0100" or "T0404" to "T0400". Programming "T0" (or "T0000") will result in an invalid tool number error.
During an automatic tool change the control powered the index solenoid, then waited for the turret to unlock prior to rotation, but the turret-locked sensor did not open within one second to indicate the turret was successfully unlocked.
This could be due to a pneumatic failure, a mechanical jam, or failure to get power to the index solenoid.

During an automatic tool change, the turret failed to arrive at the target position within four seconds.
If the turret did not rotate at all, then the problem could be a pneumatic failure, a mechanical jam, or failure to get power to the index solenoid.
If the turret rotated continuously for four seconds (going more than one full turn in the process) then the problem could be a faulty turret position encoder.

At the completion of an automatic tool change, after the turret had locked back down, the position shown by the turret position encoder did not match the target position.
This could be due to turret position encoder failure or misalignment, or due to a hydraulic or mechanical failure which delayed the deceleration and stopping of turret rotation.

The CNC program, in combination with the current Spindle Speed Override setting, has requested a spindle RPM lower than the minimum allowed RPM set in the Control Configuration.
No action is required, but be aware that the spindle will be running at the minimum allowed RPM, and therefore will be running faster than the requested or programmed speed.
The PLC program requested display of a message on the screen, but the provided message code was not valid.
This indicates an error in the PLC program. Report the message to your dealer, along with the value in PLC variable W16.
