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 work coordinate system 

 (absolute 

coordinate) 

•

 

Current position in the machine coordinate system 

 (machine 

coordinate)

  - 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. 
 

  - Setting the relative coordinates 

The current position of the tool in the relative coordinate system can 
be reset to 0 or preset to a specified value as follows:

Workpiece Coordinate System Preset (15-inch Display Unit) 

 
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 

1 

Press function key 

. 

2 

Press vertical soft key [ALL].   

3 

Enter the axis name (

, 

, ...) and 

 

. 

4 

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).

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

n 

:  Number of axes 

fi 

:  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.

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-12.3.18. 
 

 - 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.

Setting the Floating Reference Position (15-inch Display Unit) 

 
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 

1  Press function key 

  to display a screen used for displaying 

the current position.   

2  Move the tool to the floating reference position by jogging. 
3  Press horizontal soft key [SET FRP].   
4 

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 horizontal 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). 

5 

In step 3, the floating reference position along a specified axis 
can also be stored by entering the axis name (such as 

 or 

) and pressing horizontal 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.
