And in addition, DNC operation mode can be selected by combining the memory operation (MEM) mode
setting and the DNCI signal. Manual reference position return mode can be selected by combining the
manual continuous feed (JOG) mode setting and the ZRN signal.
The currently selected operation mode can be posted by outputting the operation mode check signal.

Note

Precautions on modes and mode switching

NOTE

1 In MDI mode, the cycle start lamp signal STL turns to “0” and the CNC stops as

soon as the commands entered via the MDI have been executed. But the feed
hold lamp signal SPL does not turn to “1”. Therefore, another command can be
entered from the manual data input unit under this condition.

2 Manual operation in jog feed mode

(1) When bit 0 (JHD) of parameter No. 7100 is set to 0

Only jog feed is possible.

(2) When bit 0 (JHD) of parameter No. 7100 is set to 1

Both jog feed and manual handle feed are possible, provided the manual
handle feed function is installed.

3 Manual operation in manual handle/incremental feed mode.

(1) When the manual handle feed function is not used

Incremental feed is valid.

(2) When the manual handle feed function is used and bit 0 (JHD) of parameter

No. 7100 is set to 0

Only manual handle feed is valid.

(3) When the manual handle feed function is used and bit 0 (JHD) of parameter

No. 7100 is set to 1

Incremental feed and manual handle feed are valid.

4 When switching to manual data input mode is made during operation in memory

operation mode, the CNC enters the automatic operation stop state after
executing the command in the current block. Cycle start lamp signal STL is then
set to “0”.
In this case, feed hold lamp signal SPL is not set to “1” (Fig. 2.6 (a)).

When switching to memory operation mode is made during operation in manual
data input mode, the CNC enters memory operation mode after executing the
currently executed command. To perform memory operation at this time, the
program for MDI operation must have been executed (Fig. 2.6 (b))

NOTE

5 When the HANDLE/INC mode is selected while the CNC is operating in the MEM,

RMT or MDI mode, the automatic or MDI operation stops, the Cycle time lamp
signal STL turns to “0”, the feed hold lamp signal SPL simultaneously turns to “1”,
and the CNC enters the HANDLE/INC mode. Under these conditions, manual
handle feed or incremental feed by axis direction select signal is permitted. Since
the MEM, RMT or MDI mode commands are held, operation can be restarted by
the cycle start signal and by selecting the MDI, RMT or MEM mode. However, if
operation was stopped by switching to the HANDLE/INC mode during manual
data input or during automatic operation, it can be restarted only by reactivating
the mode in use before the operation was stopped (Fig. 2.6 (c)).

NOTE

6 When the JOG mode is selected during MEM, RMT or MDI mode operation,

operation stops, the cycle time lamp signal STL turns to “0”, the feed hold lamp
signal SPL simultaneously turns to “1”, and the CNC enters the JOG mode.

Under these conditions, manual feed by feed axis direction select signal is
permitted. Operation can be restarted by returning to the original mode, as
described for HANDLE/INC mode (Fig. 2.6 (d)). When the mode is switched to
the JOG mode during manual handle feed or during incremental feed operation,
the CNC ignores the manual handle feed or incremental feed command and
manual jog feed becomes effective. If a feed axis direction select signal turns to 1
before the JOG mode is selected, that signal is ignored. The feed axis select
signal is selected by turning the necessary feed axis direction signal to “1” after
turning all the feed axis direction select signals to “0” (Fig. 2.6 (e)).

It is possible to perform handle feed in JOG mode by activating bit 0 (JHD) of
parameter No. 7100. For details, refer to Note 2.

8 Invalid mode selection signals

When mode selection signals MD4, MD2, and MD1 are set to “0”, “1”, and “0”,
respectively, the mode before the signals are changed is selected. When mode
selection signals MD4, MD2, and MD1 have been set to “0”, “1”, and “0”,
respectively, since power-on, the MDI mode is selected.

9 Notes on output signals:

When bit 0 (JHD) of parameter No. 7100 is set to 1:
(1)  In the jog feed mode, the output signals are set as follows:
    MJ=”1”, MH=”0”
(2)  In the manual handle feed mode, the output signals are set as follows:
    MH=”1”, MINC=”0”

are “1”, ”1”, and “1”), signal for checking teach-in selection
MTCHIN<Fn003.7> and signal for checking manual handle feed selection
MH<Fn003.1> turn to "1".

The status displayed on the bottom right on screen changes to "THND".

(2) In teach-in jog feed mode (mode selection signals MD4, MD2, and MD1 are

“1”, “1”, and “0”), signal for checking teach-in selection MTCHIN<Fn003.7>
and signal for checking jog feed selection MJ<Fn003.2> turn to "1".

The status displayed on the bottom right on screen changes to "TJOG".

Signal

Rapid traversing signal RPDO<Fn002.1>

[Classification] Output signal

[Function] This signal indicates that a move command is being executed at rapid traverse.

[Output cond.] “1” indicates an axis starts moving after rapid traverse has been selected; 0 indicates that

an axis starts moving after a feedrate other than rapid traverse has been selected. This
holds true for both automatic and manual operation modes.

NOTE

1 Rapid traverse in automatic operation includes all rapid traverses in

canned cycle positioning, automatic reference position return, etc.,
as well as the move command G00. Rapid traverse in manual
operation also includes rapid traverse in reference position return.

2 Once rapid traverse has been selected, this signal remains “1”,

including during a stop, until another feedrate has been selected
and movement has been started.

interpolation, circular interpolation, helical interpolation, thread cutting, skip cutting,
or cutting in canned cycle)

CAUTION

NOTE

This signal is set to “1” even when the feedrate override is 0%, and
even during interlock.

Dwell status signal DWL <Fn526.5>

[Function] This signal indicates that dwell (G04) is in progress at the automatic operation.

[Output cond.] This signal is set to “1” in the following case:

- When dwell (G04) is being performed
This signal is set to 0 in the following case.
- When dwell (G04) is not performed

When bit 2 (DWS) of parameter No.10351 is 1, dwell status signal DWL <Fn526.5> can

be used.
