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. |
I recommend measuring tool X offsets relative to an imaginary tool nose, and Z offsets relative to an actual tool.
The procedure for this may be found at http://www.cncsnw.com/OLEL.htm, as "Method 3". However, on this machine the arbitrary X axis position set at machine home with no tool offset should be comparable to the maximum swing (e.g. 144").
You can rotate the tool turret manually or with an M function.
Indexing by tool number is not provided.
Rotate tool turret. You must hold the key down until the turret stops at the next position. | |
M6 | Index to next turret position. |
Note: as of November 2009, the tool turret is not operational
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 ordinarily judge "clockwise" and "counterclockwise" if you were looking down at the face of the table.
The spindle must be in Auto mode in order to use programmed M and S codes. The spindle must be in Manual mode in order 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 |
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 |
With the table stopped, you can momentarily jog it around at low speed with these keys:
Jog table CW (looking down at table) | |
Jog table CCW (looking down at table) |
Note that these two keys show rotation from the operator's viewpoint, rather than reflecting tool direction.
The machine has a hydraulically shifted two-speed gearbox.
You can shift gears manually with jog panel keys, or automatically with M functions:
Shift to high range (9-140 RPM) | |
M42 | |
Shift to low range (2-33 RPM) | |
M41 |
Overarm movement is powered by a 7.5HP motor on top of the column, which turns the elevation screw through a right-angle gearbox.
You can jog the overarm up and down manually whenever the hydraulic system is running and no program cycle is active. The control will automatically release the hydraulic clamps when you press a jog key, and will automatically reclamp when you release the jog key. Before movement starts there will be a short delay in order to give the clamps time to release.
Jog overarm up | |
Jog overarm down |
The table base is moved by a hydraulic piston. Movement is aided by a pneumatic "float" system which directs air pressure underneath the table base.
You can jog the table base left and right manually whenever the hydraulic system is running, the table is not turning, and no program cycle is active. The control will automatically release the clamps when you press a jog key, and will automatically reclamp when you release the key. Before movement starts there will be a short delay while the control waits for the pressure switches to indicate the clamps are released.
Jog table base left | |
Jog table base right |
The work lights will come on automatically when the control starts up. You can switch the lights off and on as needed using the jog panel key:
Switch work lights on and off |
The PLC will power the Bijur lube system whenever a program cycle, or the MDI prompt, is active.

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 the PLC input and memory locations mentioned with some of the following 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 left.
The NOPTIC1 servo drive interface board in the control cabinet is reporting a fault condition.
Check optical fibers 4 and 5 from the console to the NOPTIC1 board; check power in and out of switching power supply PS1; check the 2-wire fault cable from the NOPTIC1 board to the PLC unit. Press and release Emergency Stop to clear the fault.
