When this signal turns to “0”, the paths are synchronized by the M code. When the M
code for waiting is specified for one of paths, wait the corresponding M code is
commanded in another path, then starts to execute the next block.

Waiting signal WATO<F0063.6>(for path common signal interface)

WATO<Fn063.6>(for path individual signal interface)

[Classification] Output signal

[Function] Indicates that the M code is waiting for a path.

[Output cond.] These signals are “1” as long as:

One path is waiting for another path. That is, the signal stays “1” for the period from
when the M code for waiting is issued to one path to when the corresponding M
code is issued to another path.

This signal is “0” as long as:
-

Neither of the paths is waiting for the other.

NOTE

When the path common signal interface (bit 0 (MWT) of parameter
No. 8103 = 1) is used, F0063.6="1" results even if path 2 is placed
in the wait state.

So, when the wait state needs to be checked with each path, use
the path individual signal interface (bit 0 (MWT) of parameter No.
8103 = 0).

Position switch signals PSW17 to PSW24<Fn330>

[Classification] Output signal

[Function] These signals indicate that the machine coordinates along the controlled axes specified by

parameters Nos. 6966 to 6973 are within the ranges specified by parameters Nos. 6974 to
6989.
The position switch signal corresponding to the n-th position switch function is PSWn.
(n : 17 to 24)

[Output cond.] These signals are “1” in the following case:

When the machine coordinates along the controlled axes are within the specified
ranges.

These signals are “0” in the following case:
-

When the machine coordinates along the controlled axes are not within the specified
ranges.

NOTE

This signal is available only for the loader path.

Subscript of axis name

[Input type] Parameter input

[Data type] Byte axis

[Valid data range] 0 to 9, 65 to 90

In order to distinguish axes under synchronization control, and tandem control, specify a
subscript for each axis name.

Setting value

Meaning

Each axis is set as an axis other than synchronization axis and tandem control
axis.

1 to 9

A set value is used as a subscript.

65 to 90

A set letter (ASCII code) is used as a script.

[Example] When the axis name is X, a subscript is added as indicated below.

Setting value

Axis name displayed on a screen such as the position display screen

If a multi-path system is used, no extended axis name is used within a path, and no
subscript is set for the axis names, then the path number is automatically used as the
subscript for the axis names. Note, however, a loader path name is as follows.
-

In case that the loader path 2 does not exit: “L”

In case that the loader path 2 exits: “L1”(loader path 1), “L2”(loader path 2)

[Input type] Parameter input

[Data type] Bit machine group

#0 RST

Pressing the reset key on the MDI unit is:

Valid for two paths.

Valid only for the path selected by the path selection signal.

The reset key on the MDI unit is valid for all machine groups. So, in machine groups for
which this parameter is set to 0, a reset can be performed for all paths. In machine groups
for which this parameter is set to 1, a reset can be performed only for the path that is
selected by the path selection signal.

#1 IAL

Chose of an option concerning operation continuation when an alarm is issued, and

choice of an option concerning the start of automatic operation in alarm state:
0: When an alarm is issued, the operation is stopped with the other path(s) in same

group placed in hold state.

When the other path or paths in same group are placed in alarm state, automatic

operation cannot be started.

1: Even when an alarm is issued, the operation is continued without stopping the other

path(s).

Even when the other path or paths in same group are placed in alarm state, automatic

operation can be started.

#7 NWP

Servo activation is turned on:

Together with other machine groups. (Servo activation is not turned on until other
machine groups are ready to turn on servo activation.)

Independently of other machine groups. (Each machine group turns on servo
activation even if other machine groups are not ready to turn on servo activation.)

AUXILIARY FUNCTION

9.1

AUXILIARY FUNCTION/2ND AUXILIARY FUNCTION

Overview

Auxiliary function (M code)

When up to eight digits are specified after M code, a code signal and a strobe signal are sent to the
machine. The machine uses these signals to turn on or off its functions.
Usually, only one M code can be specified in one block. In some cases, however, up to five M codes can
be specified for some types of machine tools (see "MULTIPLE M COMMANDS IN ONE BLOCK")
Also, parameter No. 3030 can specify the maximum digits and if a specified value exceeds the maximum
digits, an alarm may be issued.

2nd auxiliary function (B code)

When up to eight digits are specified after address B, a code signal and strobe signal are sent. These
signals are used to index the rotation axis of the machine. The code signal is retained until another B code
is specified.
In each block, a single B code can be specified. The maximum number of digits that can be specified after
address B is specified in parameter No. 3033. If a specified value exceeds the maximum digits, an alarm
may be issued.
The address for specifying the 2nd auxiliary function can be changed from B to another address (A, C, U,
V, or W) by parameter setting (parameter No. 3460).

Explanation

Command format of 2nd auxiliary function

Command range

-99999999 to 99999999

Command method

The value specified after the address of the second auxiliary function is output on the code signals B00 to
B31. Note the following about a output value.

1.

When a command with a decimal point or a negative command is disabled

(When bit 0 (AUP) of parameter No. 3450 is set to 0)

When the second auxiliary function with no decimal point is specified, the specified value is output
on the code signals as is, regardless of the desktop calculator decimal point setting (bit 0 (DPI) of
parameter No. 3401).

Example:

Specified value

Output value

B10

When the second auxiliary function with a decimal point is specified, alarm PS0007 is issued.

When the second auxiliary function is specified with a negative value, alarm PS0006 is issued.
