controlled simultaneously. Alternatively, in a block where the skip
function activated by the torque–limit reached signal (G31 P99/P98)
was specified, either moving the machine along an axis was not
specified, or moving the machine along multiple axes was specified.
Specify movement only along one axis.
NOTE When the seven–soft key type display unit is used, the overall

Each axis that is controlled by the CNC (including those controlled
by the PMC) must be named. Select and set names from among X, Y, Z,
A, B, C, U, V, and W (with parameter 1020). The names of the basic
axes, however, are fixed (X, Y, and Z for the M series and X and Z
for the T series). The names of additional axes can be selected, as
desired, from the names other than those for the basic axes. The
same name cannot be assigned to more than one axis. With 2–path
control, the name of the basic axis for one path is fixed. The
names of additional axes can be optionally selected from axes
names, except axes names of basic axes by using parameter No. 1020.
For one path, the same axis name cannot be assigned to multiple
axes, but the same axis name can be used with the other path.

NOTE 1 With the T series, when G code system A is used,
neither
U, V, nor W can be used as an axis name. Only when G code system B
or C is used, U, V, and W can be used as axis names.
2 The same axis name cannot be assigned to more then one
axis.
3 When the secondary auxilliary function (option) is provided, the
address used by the secondary auxilliary function (address B with
the T series or, with the M series, the address specified in
parameter No.3460) cannot be used as an axis name.
4 With the T series, when address C or A is used for chamfering,
comer rounding, or direct drawing dimension programming (when the
CCR parameter (bit 4 of parameter No.3405) is set to 1), addresses
C or A cannot be used as an axis name.
5 Only with the T series, address E can be used as an axis name.
Address E cannot be used with the M series. When address E is used
as an axis name, note the following: – When G code system A
is used, address E is always
assigned to an absolute command.
– When an equal–lead threading command (G32) is
issued in the Series 15 command lead. Use address F to
specify the thread lead.
NOTE With 2–path control, when information (such as the current
position) about each axis is displayed on the screen, an axis name
may be followed by a subscript to indicate a path number (e.g.,X1
and X2). This is an axis name to help the user to easily understand
which path an axis belongs to. When writing a program, the user
must specify X, Y, Z, U, V, W, A, B, and C without using a
subscript.

The increment system consists of the least input increment (for
input ) and least command increment (for output). The least input
increment is the least increment for programming the travel
distance. The least command increment is the least increment for
moving the tool on the machine. Both increments are represented in
mm, inches, or degrees. The increment system is classified as
either IS–B or IS–C (Tables 1.2.2(a) and 1.2.2 (b)). Select IS–B or
IS–C using bit 1 (ISC) of parameter 1004. When selecting IS–C, the
option of increment system 1/10 is necessary.

Bit 0 (ROTx) of parameter 1006 can be used to set each axis to a
linear axis or rotation axis. Bit 1 (ROSx) of parameter 1006 can be
used to select the rotation axis type, A or B, for each axis. See
the explanation of the parameters for details of types A and B.
When the roll over function is used, the values displayed for
absolute coordinates are rounded by the shift amount per rotation,
as set in parameter No. 1260. This can prevent coordinates for the
rotation axis from overflowing. Displayed values for relative
coordinates are also rounded by the angle corresponding to one
rotation when bit 2 (RRLx) of parameter No. 1008 is set to 1.
The roll–over function is enabled by setting bit 0 (ROAx) of
parameter 1008 to 1. For an absolute command, the coordinates after
the tool has moved are values rounded by the angle corresponding to
one rotation set in parameter No. 1260. The tool moves in the
direction in which the final coordinates are closest when bit 1 of
parameter No. 1008 is set to 0. For an incremental command, the
tool moves the angle specified in the command. If the rotation axis
control function is used together with an absolute command issued
for an rotation axis, the axis rotation direction and the
coordinates of the end point are determined according to,
respectively, the algebraic sign and absolute value of a value
specified in the absolute command. The function is enabled by
selecting a roll–over function for the rotation axis (parameter No.
1008 (ROAx) = 1). If the RAAx parameter (bit 3 of No. 1008) is 1,
issuing an absolute command for a rotation axis with the roll–over
function selected causes the axis rotation direction and the
coordinates of the end point to match, respectively, the algebraic
sign and absolute value of a value specified in the absolute
command. If the RAAx parameter (bit 3 of No. 1008) is 0, the axis
rotation direction and the coordinates of the end point are caused
to match the setting of the RABx parameter (bit 1 of parameter No.
1008). (The rotation axis control function is an option.)

These signals release the specified control axes from control by
the CNC. When attachments are used (such as a detachable rotary
table), these signals are selected according to whether the
attachments are mounted. The signals can also be used for switching
the C axis and spindle on lathes.
When multiple rotary tables are used in turn, the tables must use
motors of the same model. Absolute pulse coders cannot be
used.
[Classification] Input signal
[Function] These signals detach the control axes from control.
These signals are provided for each control axis; the affixed
number of the signal name shows the control axis number.
1 ..... The 1st axis is detached. 2 ..... The 2nd axis is detached.
: : : : 8 ..... The 8th axis is detached.
DTCH 1
[Operation] When the signals are 1, the control unit operates as
follows:
1) Position control is not executed at all. Servo motor excitation
is cut.
2) Servo alarm on the axis is ignored.
3) Axis interlock signal is assumed to be zero on the detached
axis.
4) A command for automatic or manual operation is effective for the
axis, but do not execute the command. The command is accepted but
the operation is restrained, because the axis interlock is 0. In an
automatic operation, the execution may stop and hold at the
block.
5) Position display also displays the position of the detached
axis.

MCCx When an axis is released from control, control for the MCC
signal for the corresponding servo amplifier is
0 : Disabled 1 : Enabled
NOTE If the servo motor for an axis is connected to a 2–axis or
other multiaxis amplifier, releasing the axis from control causes
servo alarm 401 (V ready off) to be output. This alarm can be
disabled by this parameter. When the servo motor is disconnected
from the CNC, however, servo alarm 401 is output, regardless of the
value of the parameter, due to the nature of multiaxis
amplifier.
CAUTION When a 2–axis or 3–axis amplifier is used, releasing only
one axis from control results in the output of servo alarm 401 (V
ready off). Use 1–axis amplifiers for those axes to be released
from control, e.g., by replacing the rotary table.
NOTE 1 Controlled axis detach signals DTCH1 <G124#0>,
DTCH2
<G124#1>, DTCH3 <G124#2>, … can be changed from 1 to 0
or from 0 to 1 when the power is first turned on or when no
movement is being executed along the corresponding axis. If these
signals are changed from 0 to 1 when the tool is moving along the
corresponding axis, the axis is released from control upon
completion of the movement.
2 For these signals to be attached, parameter No. 1005#7 must be
set, indicating the axes are detachable.
3 Setting parameter No. 0012#7 from the MDI panel detaches the axes
in the same way as these signals.
4 Those axes that are released from control lose their reference
positions. Reference position return must, therefore, be performed
for the axes prior to executing move commands for the axes.
Specifying a move command before reference position return has been
performed causes alarm 224 to be output (the alarm can be disabled
by setting bit 0 (ZRNx) of parameter 1005).

The movement state of each axis can be output to the PMC.
[Classification] Output signal
[Function] These signals indicate that a control axis is moving.
The signals are provided for each control axis, and the number in
the signal name corresponds to the control axis number.

MV 1
[Output condition] The signals turn to “1” in the following cases:
. The corresponding axis has started moving.
. In manual handle feed mode, the handle feed axis of the
corresponding axis has been selected.
The signals turn to “0” in the following case: . When the move
command for the corresponding axis has been
distributed (when bit 6 (MVX) of parameter 3003 is 0)
. When deceleration for the corresponding axis has been completed
and the axis is set to the in–position condition. If in–position
check is not performed, when the deceleration for the corresponding
axis is completed. (When bit 6 (MVX) of parameter 3003 is 1)
Setting 1 in bit 7 (MVG) of parameter 3003 prevents these signals
from being output during drawing in dynamic graphics mode (drawing
without movement of the machine) in the T system. In the M system,
axis moving signals are not output.

CAUTION Axis moving signals and axis moving direction signals are
output in both automatic and manual operations.
Mirror image can be applied to each axis, either by signals or by
parameters (setting input is acceptable). All movement directions
are reversed during automatic operation along axes to which a
mirror image is applied.

However, the following directions are not reversed:
– Direction of manual operation and direction of movement, from the
intermediate position to the reference position during automatic
reference position return (for the M and T series)
– Approach direction for single direction positioning (G60) and
shift direction for boring cycles (G76 and G87) (for M series
only)
Mirror image check signals indicate whether mirror image is applied
to each axis. System variable #3007 contains the same information
(refer to the operator’s manual).
[Classification] Input signal
[Function] Apply mirror image to the specified axes.
[Operation] Apply mirror image to those axes for which the signals
are 1. These signals are provided for the controlled axes on a
one–to–one basis. A number appended to a signal represents the
controlled axis number.

the feed hold state.
[Classification] Output signal
[Function] These signals indicate the mirror image condition of
each axis. The mirror image is set by taking the logical sum of the
signal from the MDI panel and the input signal of the machine tool,
then relaying the information to the machine tool. These signals
are provided for every control axis; the numeral in the signal name
indicates the relevant control axis number.
