GENERAL CONCEPTS
1.1 M/T and CO work mode
The CNC offers all the features of the M/T model plus those specific of the CO mode.
There are 2 work modes: M/T and CO work mode. This manual refers to the CO mode.
The M or T work mode described in the installation, Operation and Programming manuals will be
used for:
•Setup.
•Editing the PLC program.
•Screen customizing.
•Canned cycle customizing.
•Eliminating certain CNC errors.
•Etc.
The CO mode lets the machine manufacturer:
•Customize the keyboard.
•Change the CNC screens.
•Design the machining operations or canned cycles.
•Create screens for diagnosis, setup, CNC-PLC status information, etc.
This manual describes how to operate with the basic or standard Fagor features and it is up to the
OEM to document all the changes and new cycles defined by him.
On CNC power-up and after the keystroke sequence [SHIFT] [RESET], the CNC displays the
standard screen for the selected work mode.
With the keystroke sequence [SHIFT] [ESC] , it is possible to switch from CO mode to M/T mode
and vice versa.
The standard screen of the CO mode depends on the model:
To customize (modify or replace) this screen, refer to the "Screen customizing" chapter of the
installation manual.

Keys related to operations or canned cycles:
[C1] gives access to cycle 1, [C2[ to cycle 2 and so on.
Each key may have up to 10 levels or variants that are selected with the [LEVEL CYCLE] key.
For example:
C1 => Cycle 1, +Level => Cycle 21, +Level => Cycle 41, ....
When pressing [C1] through [C11], the CNC recovers the last cycle (level) used in each group.
The OEM may set keys [C1] through [C11] by inserting printed strips behind the keyboard.
Keys that act like softkeys F1 through F7 in M/T mode:
Specific keys for the CO mode:
From left to right, they are used for:
•[ZERO]: Doing a home search.
•[POS.]: Executing the positioning cycle.
•[ISO]: ISO and MDI management.
•[PCALL]: To see the screens or cycles defined by the OEM.
•[HELP]: (for the M/T mode).
• [TWO-COLOR]: Selecting various states in particular cycles or screens.
•[LEVEL CYCLE]: Selecting various levels in each cycle.
Free keys:
The OEM may set the free blank keys by inserting printed strips behind the keyboard. This
chapter describes how to manage those keys.
The [SINGLE] key lets execute or simulate step by step.
The [GRAPHICS] key lets simulate the cycle or see the tool movement graphics duration
execution.
Free keys, usually to control external devices:
The OEM may set them by inserting printed strips behind the keyboard.
This chapter describes how to manage those keys.

1.3 Keyboard customizing
The machine manufacturer must use the PLC program to activate and deactivate the external
devices.
The CNC will inform the PLC about the status of each key. The corresponding register bit will be
set to 1 when the key is pressed and 0 when it is not pressed.
The register bit for each key is:
Keys [O1] through [O14] have a lamp. The status of the lamp of each key must be controlled by the
machine manufacturer through the PLC program using the input variables TCLED* indicated in the
figure.
Examples:
The [O1] key is used to control the coolant.
DFU B28R561 = CPL TCLED1
= CPL O33
A number of conditions must be met in order to activate the device that may be activated and
deactivated with the [O2] key.

2.3 Home search
Home search may be done in 2 ways:
Homing all the axes
Homing a single axis
It executes the home search subroutine defined by the OEM in general
machine parameters P34 (REFPSUB).
The CNC keeps the part zero or zero offset that is active.
If the home search subroutine has not been defined, the CNC will display the
corresponding error message.
It homes the X axis.
It homes the Z axis.
The CNC will not maintain the part zero or zero offset active at the time and
assumes the machine reference zero as the new part zero.

2.4 Jog movement
The axes of the machine can move as follows:
•Movement to the programmed coordinate.
•Incremental move.
•Continuous movement.
•Movement with an electronic handwheel.
2.4.1 Movement to the programmed coordinate
The axes move one by one. With the feedrate «F» and % currently selected.
[X] Coordinate [START] [Z] Coordinate [START]
2.4.2 Incremental movement
Turn the JOG switch to one of the incremental jog positions.
JOG
The incremental movement must be made one axis at a time. To do that, press
the JOG keys for the direction of the axis to be jogged.
Every time a key is pressed, the corresponding axis moves the amount set
by the switch. This movement is made at the selected feedrate «F».

2.4.3 Continuous movement
Depending on the value assigned to general logic input "LATCHM", the movement will be carried
out in one of the following ways:
•The axis will move only while the corresponding jog key is kept pressed.
•The axis will start moving from the moment the JOG key is pressed until the same is pressed
again, or another JOG key is pressed. In this case, the movement will be transferred to that
indicated by the new key.
The following cases are possible when working with "F" in mm/rev:
A. The spindle is turning clockwise or counterclockwise.
The CNC moves the axes at the programmed F.
B. The spindle is stopped, but a spindle speed S has been selected.
Feature available at the TCO model when working in G95.
The CNC calculates the feedrate F in mm/min for the theoretical S and moves the axis.
For example if «F 2.000» and «S 500»:
Feedrate = F (mm/rev) x S (rev/min) = 2 x 500 = 1000 mm/min.
The axis moves at a feedrate of 1000 mm/min.
C. The spindle is stopped and no spindle speed S has been selected.
Feature available at the TCO model when working in G95.
The machine does not move, only with rapid movements. When pressingthe rapid key and the
corresponding axis key.
Place the left switch in the continuous-jog position and select at the right switch the
percentage (0% to 120%) of the feedrate to be applied.
The continuous jog must be made one axis at a time. To do that, press the
JOG keys for the direction of the axis to be jogged.
The axis moves at a feedrate equal to the selected percentage (0% to 120%)
of feedrate «F».
If while jogging an axis, this key is pressed (rapid), the axis will move at the maximum
feedrate possible, set by axis machine parameter "G00FEED". This feedrate will be
applied while the key is kept pressed and the previous feedrate will be restored when that
key is released.

2.4.4 Movement with an electronic handwheel
To move any of them, turn the switch to any of the handwheel positions.
Positions 1, 10 and 100 indicate the multiplying factor being applied besides the internal x4 to the
feedback pulses supplied by the electronic handwheel.
For example, if the manufacturer has set a distance of 0.100 mm or 0.0100 inches per handwheel
turn, thus:
There are 3 operating modes with handwheels:
Standard handwheel:
With the general handwheel, select the axis to be moved and turn the handwheel.
With individual handwheels, turn the handwheel associated with the axis to be moved.
"Path handwheel" mode:
For chamfering and rounding corners.
2 axes are moved along a selected path (chamfer or rounding) by moving a single handwheel.
This feature must be managed from the PLC.
The general handwheel is assumed as the "path handwheel" or the individual handwheel
associated with the X axis (MCO model) or Z (TCO model).
"Feed handwheel" mode:
To control the feedrate of the machine.
This feature must be managed from the PLC.
The various handwheel configurations are:
General handwheel: It can be used to jog any axis one by one.
Select the axis and turn the handwheel to move it.
Individual handwheel:It replaces the mechanical handwheels.
Up to 3 handwheels can be used (one per axis).
It only moves the axis it is associated with.

When jogging with individual handwheels, it may happen that depending on the
turning speed and the selector switch position, the CNC be demanded a faster
feedrate than the maximum allowed. The CNC will move the axis the indicated
distance but at the maximum feedrate allowed.
