Explanation
- Coordinate display

The current positions of the tool in the following coordinate systems
are displayed at the same time:

•

Current position in the relative coordinate system

(relative

coordinate)

•

Current position in the workpiece coordinate system

(absolute

coordinate)

•

Current position in the machine coordinate system

(machine

coordinate)

•

Distance to go (distance to go)

- Distance to go

The distance remaining is displayed in the MEMORY or MDI mode.
The distance the tool is yet to be moved in the current block is
displayed.

- Machine coordinate system

The least command increment is used as the unit for values displayed
in the machine coordinate system. However, the least input increment
can be used by setting bit 0 (MCN) of parameter No. 3104.

- Resetting the relative coordinates

The total position display screen also supports the resetting of the
relative coordinates to 0 or presetting of them to specified values. See
the procedure for resetting the relative coordinates described in
Subsection III-12.1.2

12.1.4

Workpiece Coordinate System Preset

If a workpiece coordinate system has been shifted with manual
intervention or any other operation, an MDI operation can be
performed to preset the system to a workpiece coordinate system that
is offset by a workpiece origin offset, from the machine zero point that
has been set before the shifting.
A command (G92.1) can be programmed to preset a workpiece
coordinate system. (See II-7.2.4.)

Procedure for the workpiece coordinate system preset

Procedure

Press function key

Press soft key [(OPRT)].

Enter the axis name (

, ...) and

Press soft key [PRESET].

Explanation
- Operation mode

This function can be executed when the reset state or automatic
operation stop state is entered, regardless of the operation mode.

- Presetting relative coordinates

As with absolute coordinates, bit 3 (PPD) of parameter No. 3104 is
used to specify whether to preset relative coordinates (RELATIVE).

Actual Feedrate Display

The actual feedrate on the machine (per minute) can be displayed on a
current position display screen or program check screen.
On the 12 soft keys display unit, the actual feedrate is always
displayed.

Display procedure for the actual feedrate on the current position display screen

Procedure

1 Press the function key

to display a current position

display screen. At the location indicated by

, an actual

feedrate is displayed.

The actual feedrate is displayed in units of millimeter/min or inch/min
(depending on the specified least input increment) under the display of
the current position.

Explanation
- Actual feedrate value

The actual rate is calculated by the following expression:

∑

(fi)

Fact

＝

: Number of axes

: Cutting feed rate in the tangential direction of

each axis or rapid traverse rate

Fact : Actual feedrate displayed

The display unit:

mm/min (metric input).

inch/min (Inch input, two digits below the decimal point are
displayed.)

- Actual feedrate display of feed per revolution

In the case of feed per revolution and thread cutting, the actual
feedrate displayed is the feed per minute rather than feed per
revolution.

- Actual feedrate display of rotary axis

In the case of movement of rotary axis, the speed is displayed in units
of deg/min but is displayed on the screen in units of input system at
that time. For example, when the rotary axis moves at 50 deg/min, the
following is displayed: 50 mm/min (in metric input) or 0.50 inch/min
(in inch input).

- Actual feedrate display on the other screen

The program check screen also displays the actual feedrate.

Display of Run Time and Parts Count

The run time, cycle time, and the number of machined parts are
displayed on the current position display screens.

Procedure for displaying run time and parts count on the current position display
screen

Procedure

1 Press the function key

to display a current position

display screen. At the location indicated by

The number of machined parts (PART COUNT), run time (RUN
TIME), and cycle time (CYCLE TIME) are displayed under the
current position.

Explanation
- PART COUNT

Indicates the number of machined parts. The number is incremented
each time M02, M30, or an M code specified by parameter No. 6710
is executed.

- RUN TIME

Indicates the total run time during automatic operation, excluding the
stop and feed hold time.

- CYCLE TIME

Indicates the run time of one automatic operation, excluding the stop
and feed hold time. This is automatically preset to 0 when a cycle start
is performed at reset state. It is preset to 0 even when power is
removed.

- Display on the other screen

Details of the run time and the number of machined parts are
displayed on the setting screen. See III-12.3.3.

- Parameter setting

The number of machined parts and run time cannot be set on current
position display screens.
The number of machined parts and run time cannot be set on current
position display screens. They can be set by parameters Nos. 6711,
6751, and 6752 or on the setting screen.

- Incrementing the number of machined parts

Bit 0 (PCM) of parameter No. 6700 is used to specify whether the
number of machined parts is incremented each time M02, M30, or an
M code specified by parameter No. 6710 is executed, or only each
time an M code specified by parameter No. 6710 is executed.

12.1.7

Setting the Floating Reference Position

To perform floating reference position return with a G30.1 command,
the floating reference position must be set beforehand.

Procedure for setting the floating reference position

Procedure

Press function key

to display a screen used for displaying

the current position.

Move the tool to the floating reference position by jogging.

Press soft key [(OPRT)].

Press soft key [SET FRP].

To register the floating reference positions for all axes, press soft
key [ALL AXIS].

To register the floating reference position of a specific axis, enter
the name of the axis (

, etc.), then press soft key

[AXIS

NAME]. Two or more names can be entered consecutively

(e.g., )

[AXIS NAME]).

The above operation stores the floating reference position. It can
be checked with parameter (No. 1244).

In step 4, the floating reference position along a specified axis
can also be stored by entering the axis name (such as

) and pressing soft key [SET FRP].

Explanation
- Presetting the relative coordinate system

When bit 3 (FPC) of parameter No. 1201 is set to 1, the floating
reference position can be registered, while the relative position display
can be preset to 0.
