The control starts up in Incremental jog mode. To jog the axes in continuous movement, you need to press the INCR/CONT key to switch from incremental to continuous jog mode.

Work Lights

The work lights will come on automatically when the machine is powered up.

You can turn the lights off and on by pressing the work light key on the jog panel.

Table Rotation Controls

You can control table ("spindle") rotation speed and direction manually with jog panel keys, or automatically with program codes.

Note that table direction is judged by tool direction. "Forward" or "Clockwise" is the direction you would run a standard twist drill. This is opposite how you would judge "clockwise" and "counterclockwise" if you were looking at the face of the table.

The spindle must be in Auto mode to use programmed M and S codes. The spindle must be in Manual mode 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 tool)
Select spindle reverse (CCW tool)
Start spindle
Stop spindle

In Auto mode, you can control operation and direction with these codes:

M3 Start spindle forward (CW tool)
M4 Start spindle reverse (CCW tool)
M5 Stop spindle
Snnn Set speed to nnn RPM or SFM
G50 Snnn Limit speed to nnn RPM when
using constant surface speed mode

In constant-RPM mode (G97) the S code specifies RPM. In constant surface speed mode (G96) the S code specifies SFM (surface feet per minute).

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

Table Jog for Setup

With the table stopped, you can momentarily jog it around at low speed with these keys:


or
Jog table reverse (CW if looking down at table)

or
Jog table forward (CCW if looking down at table)

Gear Shifters

The machine has a hydraulically shifted 2-speed gearbox.

Per management request, the CNC control has (as of April 2021) no provision for shifting ranges. The machine is always used in the high gear range.

Crossrail Jogging

Rail movement is powered by a 15HP motor on top of the bridge, which turns the elevation screws through right-angle gearboxes.

You can jog the rail up and down manually whenever Emergency Stop is released, the table is stopped, and no program cycle is active.


or
 + 
Jog Crossrail Up
Clamp or Unclamp Crossrail

or
 + 
Jog Crossrail Down

Before moving the crossrail, you must first release the clamps with the Rail Clamp/Unclamp key.

If the rail is clamped when you press the Rail Clamp/Unclamp key, then then the control will drive to the unclamped position.

If the rail is unclamped or in between states when you press the Rail Clamp/Unclamp key, then the control will drive to the clamped position.

G28 Return Point

Most CNC programs will return the axes to the G28 return point (return point #1) at the start and end of a job, and during tool changes. The control will also move to that position if you press the Tool Check key while no program cycle is running (e.g. during setup and manual operations).

By default, the position for the G28 return point is machine zero: ram all the way up, carriage all the way right.

If tooling or the workpiece temporarily prohibits moving all the way to machine zero, you can change the X and/or Z position for G28. To do so:

  1. Press F1/Setup
  2. Press F1/Part
  3. Press F9/WCS
  4. Press F1/Return
  5. Use the arrow keys to select the Z axis (first line) or X axis (second line) of the first return point (the G28 position).
  6. Enter zero (0.0) if you want the axis to retract all the way to its machine home position. Enter a negative number if you want it to stop closer to the work.
  7. Press F10/Save
  8. Press ESC three times to return to the main screen

Axis Way Lube System

The control will automatically operate the way lube pump any time an automatic program cycle is running. The way lube system will not operate when the machine is idle, or is being operated manually (e.g. with jogging controls).

Machine Parameter 179 controls the interval between way lube cycles, and the operating time for a cycle. The hundreds place of the Parameter 179 value is the lube cycle interval in minutes. The tens and ones place is the run time in seconds. For example, a value of 2010 means to run the pump for 10 seconds, every 20 minutes of program cycle time.

If the lube pump fails to build output pressure within the time specified in Parameter 721 (in seconds), then a fault will be triggered.

Once lube pressure is up, and the pump has been turned back off, the control will monitor to see that the lube pressure bleeds off as expected. If the lube pressure does not drop within the time specified in Parameter 722 (in seconds), then a fault will be triggered.

Jog Panel Summary

The Auxiliary keys on the jog panel have the following functions:

No function Work Light Off/On Jog Crossrail Up
No function No function Unclamp or Clamp Crossrail
No function No function Jog Crossrail Down
No function Jog Table Reverse Jog Table Forward

MPG Handwheel Pendant

In addition to the console jog panel, the machine is equipped with a Centroid WMPG-4 wireless MPG handwheel pendant. The handwheel pendant can be used for axis jogging and for cycle start, feed hold, table and crossrail control.

To use the MPG pendant, first press its silver power button. The display on the pendant should show a copy of the DRO axis position display.

To move an axis using the handwheel:

  1. Turn the axis-select knob to the axis you want to move
  2. Turn the increment-select knob to 1X, 10X or 100X.
  3. Turn the handwheel to move the axis
  4. When you are done using the MPG handwheel for a while, turn the axis-select knob back to the OFF position.

The handwheel can also be used as a spindle speed override control, or as a feedrate override control.

To adjust spindle speed, turn the increment-select knob to SPIN, then turn the wheel CW to increase spindle speed, or CCW to decrease spindle speed.

To adjust feedrate, turn the increment-select knob to FEED, then turn the wheel CW to increase the feedrate override, or CCW to decrease the feedrate override.

NOTE: if you use the WMPG-4 handwheel to change the feedrate override setting, this takes precedence over the position of the knob on the console jog panel. However, as soon as you turn the knob on the console jog panel again, then its setting will take over. This could cause an abrupt change in axis speed, especially if you had used the WMPG-4 wheel to turn the feedrate override down.

In addition to the MPG handwheel, the WMPG-4 pendant has Cycle Start, Feed Hold, and Tool Check keys. These keys function the same as the equivalent keys on the main jog panel.

There are two axis jog keys: "JOG -" and "JOG +". These keys will jog whichever axis is selected with the axis-select switch, in the jog mode (FAST/SLOW) that is selected on the main jog pendant.

In addition, with the axis-select switch in the "4th" position, the "JOG -" and "JOG +" keys can be used to jog the crossrail down and up, provided the crossrail is unclamped and no program cycle is running.

There are four customizable Macro keys. As of May 2024, these keys have the following functions:

Table Jog Reverse
Table Jog Forward
no function
no function

The WMPG-4 pendant relies on a USB-connected wireless transceiver. This transceiver antenna sits on top of the console, and should be plugged into one of the console USB ports.

The WMPG-4 pendant requires two AA batteries. The battery compartment is on the back, underneath the protective rubber cover.

Troubleshooting

Fault, Error and Warning Messages

Any time the control cannot complete its tasks normally, it will display a message in the scrolling message box, in the upper right corner of the screen, explaining what went wrong. You can use the touchscreen or a mouse to scroll up (back) in the message box to view the most recent 10 or so messages.

You can view older messages in the error message log, accessible from the F7/Utility menu:

  1. Press F7 for Utility
  2. Press F9 for Logs
  3. Press F1 for Errors
  4. Use PgUp and PgDn as needed to scroll through the pages of messages
  5. Press ESC three times to return to the control's main screen
Note that, in the log display, messages are shown in reverse order (newest at the top).

Most common messages are described in Chapter 13 of the Centroid T-Series Operator's Manual.

The machine-specific PLC program can generate several of its own fault, error and warning messages, in addition to those listed in the Centroid operator's manual. The machine-specific messages are listed later in this section.

PLC Diagnostic Display

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 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.

Clearing Faults

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.

Opening the Control Cabinet Doors

In some cases, it may be necessary to open the control cabinet doors while power is on. For example, servo drive and spindle drive fault conditions can be more readily identified using the codes displayed on, or stored in, the drive units themselves.

WARNING: Use appropriate caution when working in the control cabinets while power is on. Lethal voltages, up to 480VAC and 700VDC, are present on many components.

Message Descriptions

"9001 !!! PLC EXECUTION FAULT !!!"

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.

"9030 SPINDLE FAULT!"

The GA800 spindle drive (VFD) is reporting a fault condition.

This may occur if emergency stop is pressed, and then released within less than one second. In this case the safety relay (SR1) does not have time to reset, and so does not close again when emergency stop is released. Press emergency stop; wait at least two seconds; then release emergency stop.

Other spindle faults may result from over-voltage while decelerating, or from overload during spindle startup with a heavy load.

If the cause is not immediately evident, then check the LCD display on the spindle drive itself, in the right side of the cabinet.

You can review past drive fault conditions using the drive's parameters menu. The ten most recent fault codes are in parameters U3-01 through U3-10. See chapters 4 and 7 of the GA800 drive technical reference manual.
