1.3 Control Axes and Operation Modes
1.3.1 Tape (RS-232C Input) Mode
In this mode, operation is performed using the machining program data from the RS-232C interface built in
the CNC unit. A paper tape reader must be provided if machining programs on paper tape are to be run.
1.3.2 Memory Mode
The machining programs stored in the memory of the CNC unit are run.
1.3.3 MDI Mode
The MDI data stored in the memory of the CNC unit is executed. Once executed, the MDI data is set to the
"setting incomplete" status, and the data will not be executed unless the "setting completed" status is
established by screen operations.
1.3.4 High-Speed Program Server Mode
1.3.4.1 CF Card in Control Unit
The machining program stored in CF card can be operated by installing a CF card in the control unit CF
(compact flash) card interface.
Machining programs can be copied to CF card with the front IC card or Ethernet on the input/output screen.
When a machining program stored in CF card is searched while "DS" is selected for device during operation
search, the machining program in CF card can be operated as a main program. (The operation mode is
"memory mode".)
Also, when "M198 Pp;" is commanded in the main program, the machining program in CF card can be called
and operated as a sub program.
Macros such as WHILE, IF and GOTO can be used during high-speed program server mode, as well. Also,
calling the sub program and macro program stored in memory or CF card is possible during high-speed
program server mode operation.

1.3.5 Front IC Card Mode
The machining program stored in PCMCIA card can be operated by installing a PCMCIA card on the front of
control unit.
When a machining program stored in PCMCIA card is searched while "Memory Card" is selected for device
during operation search, the machining program in PCMCIA card can be operated as a main program. (The
operation mode is "memory mode".)
Also, when "M98 Pp, Dd;" ("d" for designating a unit) is commanded in the main program, the machining
program in PCMCIA card can be called and operated as a sub program.
Macros such as WHILE, IF and GOTO can be used during IC card operation, as well. Also, calling the sub
program and macro program stored in memory or PCMCIA card is possible during IC card operation.
1.3.6 Hard Disk Mode
The machining program stored in the hard disk can be operated when using a high-resolution type display (a
display with a hard disk mounted).
When a machining program stored in hard disk is searched while "HD" is selected for device during
operation search, the machining program in the hard disk can be operated as a main program. (The
operation mode is "memory mode".)
Also, when "M98 Pp ,Dd;" ("d" for designating a unit) is commanded in the main program, the machining
program in the hard disk can be called and operated as a sub program.
Macros such as WHILE, IF and GOTO can be used during hard disk operation, as well. Also, calling the sub
program and macro program stored in memory or the hard disk is possible during hard disk operation.

2.1 Data Increment
2.1.1 Least Command Increment
The data increment handled in the controller includes the input setting increment and command increment.
Each type is set with parameters.
(1) The input setting increment indicates the increment handled in the internal processing of the
controller. The counter and tool compensation data, etc., input from the screen is handled with this
increment. This increment is applied per part system (1st to 4th part system, PLC axis).
(Note) The inch and metric systems cannot be used together.
(2) The command increment indicates the command increment of the movement command in the
machining program. This can be set per axis.
(Note) The inch and metric systems cannot be used together.
2.1.1.1 Least Command Increment 1 μm (Input Setting Increment 1μm)
It is possible to command 0.001mm for the linear axis and 0.001° for the rotation axis.
2.1.1.2 Least Command Increment 0.1 μm (Input Setting Increment 0.1μm)
It is possible to command 0.0001mm for the linear axis and 0.0001° for the rotation axis.
