NOTE

Each PMC of a multipath PMC system has an independent signal area. The F,

G, X, and Y signal addresses of each PMC begin with 0. On the other hand, the
F and G signal addresses from the viewpoint of the CNC are fixed for each path
number. Note that the F and G signal addresses used in programming of each
ladder are different from those from the viewpoint of the CNC.

NOTE

1 Each of the parameters of the bit, bit machine group, bit path, bit axis, and bit

spindle types consists of 8 bits for one data number (parameters with eight
different meanings).

2 For machine group types, parameters corresponding to the maximum number of

machine groups are present, so that independent data can be set for each
machine group.

3 For path types, parameters corresponding to the maximum number of paths are

present, so that independent data can be set for each path.

4 For axis types, parameters corresponding to the maximum number of control

axes are present, so that independent data can be set for each control axis.

5 For spindle types, parameters corresponding to the maximum number of

spindles are present, so that independent data can be set for each spindle axis.

6 The valid data range for each data type indicates a general range. The range

varies according to the parameters. For the valid data range of a specific
parameter, see the explanation of the parameter.

Some parameters handle these types of

Notes on various kinds of data

CAUTION

Machining programs, parameters, offset data, etc. are stored in the CNC unit

internal non-volatile memory. In general, these contents are not lost by the
switching ON/OFF of the power. However, it is possible that a state can occur
where precious data stored in the non-volatile memory has to be deleted,
because of deletions from a maloperation, or by a failure restoration. In order to
restore rapidly when this kind of mishap occurs, it is recommended that you
create a copy of the various kinds of data beforehand.
The number of times to write machining programs to the non-volatile memory is
limited.
You must use "High-speed program management" when registration and the
deletion of the machining programs are frequently repeated in such case that the
machining programs are automatically downloaded from a personal computer at
each machining.
In "High-speed program management", the program is not saved to the
non-volatile memory at registration, modification, or deletion of programs.
Please make the application software by using FOCAS2/ C Language Library to
save the changed programs to the non-volatile memory when "High-speed
program management" is used.

1.2 SETTING EACH AXIS

1.2.1 Name of Axes

Overview

Each axis that is controlled by the CNC (including those controlled by the PMC) must be named.
To name an axis, select a desired character from among A, B, C, U, V, W, X, Y, and Z and set the
character as the first axis name character (parameter No. 1020).

NOTE

1 The same axis name cannot be assigned to more then one axis. (The same axis

name can be used on different paths.)

2 With the lathe system, 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.

3 When a multiple repetitive canned turning cycle is used, only X, Y, or Z can be

used as the address of a target axis.

- Extended axis name

The extended axis name function can be used to use an axis name consisting of up to three characters.
To use an extended axis name:
<1> Enables the extended axis name function (set bit 0 (EEA) of parameter No. 1000 to 1).
<2> Set the first character (A, B, C, U, V, W, X, Y, or Z) in parameter No. 1020 (first axis name

character).
<3> Set the second character (’0’ to ’9’ and ’A’ to ’Z’) in parameter No. 1025 (first axis name character).
<4> Set the third character (’0’ to ’9’ and ’A’ to ’Z’) in parameter No. 1026 (first axis name character).

NOTE

1 If the second axis name character is not set for an axis, the third axis name

character is invalid.

2 When setting 0 to 9 for the second axis name character, do not set A to Z for the

third axis name character.

3 When an axis name ends with a numeric character, an equal sign (=) is required

to be specified between the axis name and a setting.

4 In a macro call, no extended axis name can be used as an argument.

- 2 -

B-64483EN-1/03 1.AXIS CONTROL

NOTE

5 If at least one axis in a path uses an extended axis name when bit 2 (EAS) of

parameter No. 11308 is set to 0, subscripts (parameter No. 3131) cannot be
used for axis names in the path.

6 When G code system A is used for a lathe system, X, Y, Z, or C may be used for

the first axis name character of an axis. In this case, when a command
containing U, V, W, or H as the first axis name character is specified, it is used
as the incremental command for the corresponding axis.

7 In a multipath system, if an extended axis name is not used on a path or if bit 2

(EAS) of parameter No. No.11308 is valid and subscripts (parameter No. 3131)
are not set for axis names, the path name will automatically be the subscript for
axis names. To disable the display of axis name subscripts, set a blank (32) of
ASCII code in the parameter for specifying an axis name subscript.

8 If the custom macro function is enabled, the same extended axis name as a

reserved word cannot be used. Such an extended axis name is regarded as a
reserved word.

Because of reserved words of custom macros, extended axis names that start

with the following combinations of two characters cannot be used:

1.2.2 Increment System

Overview

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.
There are five types of increment systems as listed in Table 1.2.2 (a). A desired type can be set for each
axis using the corresponding bit 0 (ISA), 1 (ISC), 2 (ISD), or 3 (ISE) of parameter No. 1013.
The least input increment can be set to metric input or inch input using the G code (G20 or G21) or
setting parameter (bit 2 (INI) of parameter No. 0000).
The least command increment is set to either metric or inch system depending on the machine tool in
advance. Select the metric or inch system using bit 0 (INM) of parameter No. 1001 in advance.
Any combined use of the inch and metric systems is not allowed. There are functions that cannot be used
across axes with different increment systems (such as circular interpolation and cutter compensation).
IS-C, IS-D, and IS-E are optional functions.

NOTE

1 The unit (mm or inch) in the table is used for indicating a diameter value for

diameter programming (when bit 3 (DIA) of parameter No. 1006 is set to 1) or a
radius value for radius programming.

2 Some increment systems are unavailable depending on the model. For details,

refer to “DESCRIPTIONS” (B-64482EN).

1.2.3 Diameter and Radius Setting Switching Function

Overview

Usually, whether to use diameter specification or radius specification to specify a travel distance on each
axis is uniquely determined by the setting of bit 3 (DIAx) of parameter No. 1006. However, this function
enables switching between diameter specification and radius specification by using a signal or G code.
Thus, a coordinate, program, and so forth can be specified by switching between diameter specification
and radius specification for each controlled axis.

Explanation

- Selection of a diameter/radius specification switching method

Two methods are available for switching between diameter specification and radius specification:

1) Signal

2) G code
Use bit 5 (PGD) of parameter No. 3400 to determine which method to use.

- Switching method using a signal

For switching between diameter specification and radius specification, set the diameter/radius
specification switch signal from DI1 to DI8 (input signals) corresponding to a desired axis, from 0 to 1.
If an input signal is set from 0 to 1, and radius specification is selected (with bit 3 (DIAx) of parameter
No. 1006 = 0) for the axis corresponding to the input signal, the specification method switches to
diameter specification; the specification method switches to radius specification if diameter specification
is selected (with bit 3 (DIAx) of parameter No. 1006 = 1).
During switching, the diameter/radius specification switching in-progress signal from DM1 to DM8
(output signals) corresponding to a switched axis is output.
To return the diameter/radius specification of an axis to the original state, set the setting of the
corresponding diameter/radius specification switch signal from DI1 to DI8, from 1 to 0.

NOTE

1 When operating an input signal by using an M code, for example, during

automatic operation, perform a switching operation according to the method
below to reflect the state of diameter/radius specification switching in the
execution block correctly.
As an auxiliary function for switching, use an unbuffered M code (parameter No.
3411 and up). Use the following sequences for a specified M code:

- When switching is performed
code → Input signal ON → Confirmation of output signal ON → FIN

Ｍ

- When switching is cancelled
code → Input signal OFF → Confirmation of output signal OFF → FIN

Ｍ

If a diameter/radius specification switch signal is operated during automatic

operation without following the sequences above, alarm PS5320 is issued.

2 If a diameter/radius specification switch signal is operated while a movement is

made on an axis subject to switching, alarm PS5320 is issued.

- Switching method using a G code (programmable diameter/radius
specification switching)

The format of a G code for diameter/radius specification switching is as follows:

- 9 -

1.AXIS CONTROL B-64483EN-1/03

Format

G10.9 IP_ ;

IP_ : Address and command value of an specified axis subject to diameter/radius

specification switching
Specify 0 or 1 as the command value.
0: Radius specification
1: Diameter specification

NOTE

1 Specify G10.9 in a single block specifying no other codes.
2 After an axis address, specify a command value without using the decimal point.

- Switching operation

According to the switching methods above, diameter/radius specification is internally switched as
described below.

1) Switching using a signal

- When parameter DIAx = 0 (radius specification)
→ Operation is performed with diameter specification.

- When parameter DIAx = 1 (diameter specification)
→ Operation is performed with radius specification.

2) Switching using a G code

- When the specified address value = 0 (radius specification)
→ Operation is performed with radius specification.

- When the specified address value = 1 (diameter specification)
→ Operation is performed with diameter specification.

NOTE

1 When the diameter/radius specification switching state is to be cancelled using a

reset or mode switching at the time of signal-based switching, the input signal
needs to be operated.

2 Switching using a G code is cancelled by a reset.

- Selection of a machine coordinate system

When switching between diameter specification and radius specification is made with the function for
dynamic switching of diameter/radius specification, coordinates in the machine coordinate system select
command (G53) follow the setting of bit 7 (PDM) of parameter No. 11222. If the PDM bit of the
parameter is 0, coordinates are switched between diameter and radius specification. if the PDM bit of the
parameter is 1, coordinates follow the setting of bit 3 (DIAx) of parameter No. 1006.

For offset data, the settings of bit 1 (ORC) of parameter No. 5004 and bit 2 (ODI)

of parameter No. 5004 have priority.

- Switchable data and commands

For the following data and commands, diameter/radius specification switching is performed according to
the specified specification method:

- Programmed move command

- Current position display

- Workpiece coordinate system preset

- Movement based on the manual numeric command G00 or G01

- Use with other functions

Diameter/radius specification switching cannot be performed for an axis on which a movement is being
made with any of the functions indicated below.
Moreover, none of the functions indicated below can be performed during diameter/radius specification
switching.

- Synchronous/composite control

- Superimposed Control

- Axis synchronous control

- PMC axis control

Caution

CAUTION

When switching is performed from diameter specification to radius specification,

the travel distance based on the same move command is doubled when
compared with diameter specification. So, when switching from diameter
specification to radius specification, ensure safety in machine operation.

1.2.4 Specifying the Rotation Axis

Overview

Bit 0 (ROTx) of parameter No.1006 can be used to set each axis to a linear axis or rotary axis. Bit 1
(ROSx) of parameter No. 1006 can be used to select the rotary 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 rotary 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 No. 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 (RABx) of parameter
No. 1008 is set to 0. For an incremental command, the tool moves the angle specified in the command.
If the rotary axis control function is used together with an absolute command issued for an rotary 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 rotary axis (bit 0 (ROAx) of parameter No. 1008 = 1). If the bit 3
(RAAx) of parameter No. 1007 is 1, issuing an absolute command for a rotary 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 bit
3 (RAAx) of parameter No. 1007 is 0, the axis rotation direction and the coordinates of the end point are
caused to match the setting of the bit 1 (RABx) of parameter No. 1008. (The rotary axis control function
is an option.)
For details of rotary axis control, see the Section 1.11, “ROTARY AXIS CONTROL” in this manual.

1.2.5 Controlled Axes Detach

Overview

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. When multiple rotary tables are used in turn, the tables must use motors of the same model.

WARNING

For a vertical axis, in particular, it is necessary to prepare a sequence that starts

operating the mechanical brake before the control axis detach operation.
When this method is applied to a vertical axis, special care should be taken.

Signal

Controlled axis detach signals DTCH1 to DTCH8<Gn124>

[Classification] Input signal
[Function] These signals detach the control axes from control.

NOTE

This parameter can be set for a control axis.

WARNING

When the servo motor of a controlled axis to be detached is

connected to a multi-axis amplifier such as a two-axis amplifier,
placing the axis in the control axis detach state causes the
activating current in the amplifier to drop. As a result, alarm
SV0401, "V READY OFF" is issued in the other axes. This alarm
can be suppressed by setting this parameter bit.

With this method, however, the target axis for the control axis

detach operation is placed in the servo off state (the amplifier
remains on, but no current flows through the motor). The torque of
the target axis becomes 0, so care should be taken. For a vertical
axis, in particular, it is necessary to prepare a sequence that starts
operating the mechanical brake before the control axis detach
operation. When this method is applied to a vertical axis, special
care should be taken.

Even when a controlled axis has been detached, detaching a cable

(a command cable or feedback cable) of the axis causes an alarm.

In such applications, it is impossible to perform a control axis

detach operation with a multi-axis amplifier by setting this
parameter bit. (Prepare a single-axis amplifier.)

#7 RMBx The control axis detachment signal for each axis and the setting input parameter (bit 7

(RMV) of parameter No. 0012) are:

Caution

CAUTION

When a multiaxis amplifier is used, the motor cannot be disconnected from the

amplifier. When the motor needs to be disconnected from the amplifier for

replacement of the rotary table or other reasons, a 1-axis amplifier must be

used.

NOTE

1 Controlled axis detach signals DTCH1 <G124.0>, DTCH2 <G124.1>, DTCH3

<G124.2>, 0 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, bit 7 (RMB) of parameter No. 1005 must be

set, indicating the axes are detachable.
3 Setting bit 7 (RMV) of parameter No. 0012 from the MDI unit 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 PS0224 to be

output.
If an axis for which an absolute position detector is used (bit 5 (APC) of

parameter No. 1815 is set to 1) is released from control, the correspondence

between the machine position and reference position is lost. Consequently, bit 4

(APZ) of parameter No. 1815 indicating that the correspondence is established is

set to 0, resulting in alarm DS0300. After an axis is released from control,

perform reference position return to bring the machine position into

correspondence with the reference position.

1.2.8 Follow-up

Overview

If the machine moves in the state in which position control on controlled axes is disabled (during
servo-off, emergency stop, or servo alarm), feedback pulses are accumulated in the error counter. The
CNC reflects the machine movement corresponding to the error count in the current position managed by
the CNC. This operation is referred to as follow-up. When follow-up is performed, the current position
managed by the CNC does not shift from the actual machine position.
You can select whether to perform follow-up for axes when the servo is turned off.
Follow-up is always performed during emergency stop or a servo alarm.

Explanation

- When follow-up is not performed for the axes for which the servo is turned off

When signal *FLWU is 1 or bit 0 (FUPx) of parameter 1819 is 1, follow-up is not performed. The error is
added to the error counter as a servo error.
In this case, the machine moves to compensate for the error when the servo off signal changes to 0.
In general, follow-up is not used if the machine is mechanically clamped when position control is
disabled for the controlled axes.

- When follow-up is performed for the axes for which the servo is turned off

When *FLWU is 0, the follow-up function is engaged. The present position of the CNC is changed to
reset the error counter to zero. The machine tool remains in a deviated position, but since the present
position of the CNC changes correspondingly, the machine moves to the correct position when the
absolute command is next applied.
In general, follow-up should be used when motors are driven by mechanical handles.

Place the controlled axes in the servo off state, stop the current to the servo motor, which disables
position control. However, the position detection feature functions continuously, so the current position is

1.AXIS CONTROL B-64483EN-1/03

CAUTION

4 If a servo off signal is issued with the setting that does not cause follow-up to be

performed (*FLWU<Gn007.5> = 1), even if the machine is moved with external
force or other means, the machine will be retracted by the travel distance in the
servo on state and, therefore, the path will never shift in subsequent automatic
operation.
The amount of movement due to the external force in the servo off state is
regarded as a servo positional deviation and is stored inside the NC. Thus, when
a servo on signal is issued, axis moving occurs to cancel this servo positional
deviation. The machine moves at a speed in accordance with the servo loop gain
and if the amount is large, this may give the machine a shock.

1.2.11 High-Speed Position Switch

Overview

The high-speed position switch function monitors the current position at shorter intervals than the normal
position switch function to output a high-speed precise position switch signal.
In the same way as for the normal position switch function, using parameters, specify arbitrary controlled
axes and machine coordinate operating ranges for which position switch signals are output.
Up to six high-speed position signals can be output. Bit 7 (HPE) of parameter No. 8500 can be set to 1 to
use up to 16 high-speed position switch signals.

CAUTION

The high-speed position switch function is enabled after reference position return

1.2.12 Direction-Sensitive High-Speed Position Switch

Overview

The high-speed position switch function monitors the machine coordinates and move direction to output
high-speed position switch signals.
Two machine coordinates are monitored. When the tool passes through one coordinate in the specified
direction, the high-speed position switch signal is set to 1. When it passes through the other coordinate in
the specified direction, the signal is set to 0.
The output mode of high-speed position switch signals (normal mode or direction sensitive mode) is set
using parameters Nos. 8508 and 8509.
For high-speed position switch signals for which the direction-sensitive high-speed position switch signal
is used, the specified coordinates are used as follows. The maximum coordinate in each operating range
(parameters Nos. 8580 to 8589 or 12221 to 12226) is used as the coordinate which triggers the
corresponding signal to be set to 1.
The minimum coordinate in each operating range (parameters Nos. 8590 to 8599 or 12241 to 12246) is
used as the coordinate which triggers the corresponding signal to be set to 0.

Time

Fig. 1.2.12 (a) shows the output status of a direction-sensitive high-speed position switch signal when the
current position moves from a to b, c, d, e, f, and g.
The direction-sensitive high-speed position switch signal is assumed to be set as follows:

- 1 when the tool passes through P1 in the negative (↓) direction.

- 0 when it passes through P2 in the positive (↑) direction.
1 The high-speed position switch signal is set to 1 because the tool passes through P1 in the negative

direction (specified direction) when the current position moves from a to b.

2 The status of the high-speed position switch signal does not change because the tool passes through

P1 in the positive direction (not the specified direction) when the current position moves from b to c.

3 The high-speed position switch signal is set to 1 because the tool passes through P1 in the negative

direction (specified direction) when the current position moves from c to d. (The status of the signal
does not change because the signal has been set to 1.)

4 The status of the high-speed position switch signal does not change because the tool passes through

P2 in the negative direction (not the specified direction) when the current position moves from d to
e.

5 The high-speed position switch signal is set to 0 because the tool passes through P2 in the positive

direction (specified direction) when the current position moves from e to f.

6 The status of the high-speed position switch signal does not change because the tool passes through

P1 in the positive direction (not the specified direction) when the current position moves from f to g.

Signals are used to notify that the current position along an axis corresponding to each high-speed
position switch is within a range specified by a parameter.

1.3 ERROR COMPENSATION

1.3.1 Stored Pitch Error Compensation

Overview

If pitch error compensation data is specified, pitch errors of each axis can be compensated in detection
units per axis.
Pitch error compensation data is set for each compensation position at the intervals specified for each axis.
The origin of compensation is the reference position to which the tool is returned.
Pitch error compensation data can be set with external devices such as the Handy File (see Operator's
Manual). Compensation data can also be set directly with the MDI unit.
The following parameters must be set for pitch error compensation. Set the pitch error compensation
value for each pitch error compensation position number set by these parameters.
In the following example, 33 is set for the pitch error compensation number at the reference position.

• Pitch error compensation magnification (for each axis): Parameter No.3623

• Interval of the pitch error compensation positions (for each axis): Parameter No.3624

Explanation

- Specifying the compensation position

To assign the compensation positions for each axis, specify the positive direction or the negative direction
relative to the compensation position No. of the reference position. If the machine stroke exceeds the
specified range on either the positive direction or the negative direction, the pitch error compensation
does not apply beyond the range.

- Compensation position number

1536 compensation positions from No. 0 to 1535 are available on the pitch error setting screen. Assign
arbitrary positions for each axis using parameters.

- 35 -

1.AXIS CONTROL B-64483EN-1/03

The number of the compensation position at the reference position (parameter No.3620), number of the
compensation position having the smallest value (parameter No.3621), and number of the compensation
position having the largest value (parameter No.3622) must be set for each axis.
The name of each axis is displayed before the smallest compensation position number on the pitch error
setting screen.

- Interval of compensation positions

The pitch error compensation positions are equally spaced to parameter No. 3624. Set the space between
two adjacent positions for each axis.
The minimum interval between pitch error compensation positions is limited and obtained from the
following equation:
Minimum interval of pitch error compensation positions = maximum feedrate (rapid traverse rate)/7500
Unit :
Minimum interval of pitch error compensation positions: mm, inches, deg.
Maximum feed rate: mm/min, inch/min, deg/min
[Example]
When the maximum rapid traverse rate is 15000 mm/min, the minimum interval between pitch error

compensation positions is 2 mm.

Example

- For linear axis

• Machine stroke: -400 mm to +800 mm

• Interval between the pitch error compensation positions: 50 mm

• No. of the compensation position of the reference position: 40

If the above is specified, the No. of the farthest compensation position in the negative direction is as
follows:
No. of the compensation position of the reference position - (Machine stroke on the negative side/Interval
between the compensation positions) + 1= 40 - 400/50 + 1= 33
No. of the farthest compensation position in the positive direction is as follows:
No. of the compensation position of the reference position + (Machine stroke on the positive side/Interval
between the compensation positions)= 40 + 800/50= 56
The correspondence between the machine coordinate and the compensation position No. is as Fig. 1.3.1

- For rotary axis

• Amount of movement per rotation: 360°

• Interval between pitch error compensation positions: 45°

• No. of the compensation position of the reference position: 60

In the above case, the number of the most distance compensation position on the - side is equal to the
number of the compensation position of the reference position + 1 = 60 + 1 = 61 for a rotary axis.
The No. of the farthest compensation position in the positive direction is as follows:
No. of the compensation position of the reference position + (Move amount per rotation/Interval between
the compensation positions)= 60 + 360/45= 68

Note that the pitch error is not compensated in the following cases:

- When the machine is not returned to the reference position after turning on
the power. This excludes the case where an absolute position detector is
employed.

- If the interval between the pitch error compensation positions is 0.

- If the compensation position Nos. on the positive or negative direction do not

- Second stage backlash compensation output

At the point the tool moves by the distance L1 from the location where the direction of axis moving
reverses, the second stage backlash compensation output is started. And, at the point the tool moves by
the distance L2 from the location where the direction of axis moving reverses, the second stage backlash
compensation output is terminated. The total amount of backlash at the stage where the second stage
backlash compensation output is terminated, or B2, is the same as the backlash compensation set using
parameter No. No.1851. Set the distances L1 and L2, using parameters Nos. 1846 and 1847, respectively.

If backlash compensation for each rapid traverse and cutting feed is enabled (RBK, bit 4 of parameter No.
1800 = 1), the total amount of backlash compensation at the stage where the second stage backlash
compensation output is terminated, or B2, is the backlash compensation as determined by parameters Nos.
1852 and 1851, the reversed direction, and the rapid traverse/cutting feed mode. The rate of increase of
the second stage backlash compensation output remains the same as that during cutting. (Expression 1)

1.3.4 Straightness Compensation

Overview

For a machine tool with a long stroke, deviations in straightness between axes may affect the machining
accuracy. For this reason, when an axis moves, other axes are compensated in detection units to improve
straightness. This improvement results in better machining accuracy.
When an axis (parameters Nos. 5711 to 5716) moves, the corresponding compensation axis (parameters
Nos. 5721 to 5726) is compensated.
That is, the compensation axis is compensated at the pitch error compensation position (See Subsection
“Stored Pitch Error Compensation”) of the moving axis.

The compensation from point a to point b is calculated from the formula: (β-α)/(b-a).

Example

Imagine a table whose Y-axis ball screw is placed on its X-axis ball screw. If the X-axis ball screw is
inclined at a certain angle because of, for example, bending, the machining precision related to the Y-axis
becomes low because its ball screw is affected by the gradient of the X-axis ball screw. (Left figure
shown Fig. 1.3.4 (c))
Specifying the X-axis and Y-axis, respectively, as a moving axis and a compensation axis by means of
straightness compensation causes the Y-axis (compensation axis) position to be compensated according to
the X-axis (moving axis) position, thus increasing the machining precision. (Right figure shown Fig. 1.3.4
(c))

Y-axi s

B

P1, P2, P3, P4 : Points on the moving axis

The path of the B section, which is a joint between the X-axis
and Y-axis, is affected by the gradient of the X-axis because
of the structure of the table. If a command specifies
movement from P1 to P4 only along the X-axis withou
applying straightness compensation, the path of point A along
the Y-axis is affected by the gradient of the X-axis.

If a command specifies movement from P1 to P4 only along
the X-axis (moving axis), when the B section moves in th
sequence P1 → P2 → P3 → P4, straightness compensation
gives compensation amounts ε1 to ε4 to the Y-axi

of point A along the Y-axis from being affected by the gradien
of the X-axis even when the B section, which is a joint between
the X-axis and Y-axis, is affected by the gradient of the X-axis.

Note

NOTE

1 This function is an optional function.
2 To use this function, the stored pitch error compensation option is required.
3 The straightness compensation function can be used after a moving axis and its

compensation axis have returned to the reference position.

4 After setting parameters for straightness compensation, be sure to turn off the

NC power.

5 Set parameters for straightness compensation according to the following

conditions:

- The compensation at a compensation position must be within the range -127
to 127.

- Compensation positions must be set so that "a≤b≤c≤d" is satisfied.

- Compensation positions must exist between the compensation position with
the largest positive value and that with the largest negative value in the
stored pitch error compensation data for each axis. Four compensation
positions can be set to 0 at a time. In this case, compensation is not
performed.

6 To add the straightness compensation function option, the stored pitch error

compensation option is needed.

In this case, the number of compensation positions of each axis between the

compensation position with the largest positive value and that with the largest
negative value in the stored pitch error compensation data must be equal to or
less than 136.

7 Straightness compensation data is superposed on stored pitch error

compensation data and output. Straightness compensation is performed at pitch
error compensation intervals.

8 Straightness compensation does not allow the moving axis to be used as a

compensation axis. To implement such compensation, use gradient
compensation (see Subsection 1.3.8, "Gradient Compensation").

1.3.5 Straightness Compensation at 128 Points

Overview

In straightness compensation, this function sets compensation data as the compensations at individual
compensation points in the same way as in stored pitch error compensation. This enables fine
compensation to be applied.
Up to six combinations of moving and compensation axes for the straight compensation function are
allowed.

• The method of setting data, as well as the timing of compensation, is the same as that of pitch error

compensation.

• To use this function, the number of pitch error compensation points on the moving axis must not

exceed 128.

• The number of straightness compensation points is the same as that of stored pitch error

Explanation

- Relationships between pitch error compensation points and straightness

The following relationships hold:

1. δ = φ + (γ-α)

2. π＝φ + (β-α)
π and δ need not be set using parameters because they are automatically calculated from α, β, γ, and φ.

- Displaying and setting straightness compensation data

Set the compensation data for straightness compensation at 128 points on the screen for setting stored
pitch error compensation data. On this setting screen, the compensation data for straightness
compensation at 128 points can be set, starting with compensation point number 6000.

Input/output of compensation data is possible with one of the following ways:

- Input with the MDI unit

- Input with G10

- Input/output with the I/O unit interface

- Input from the PMC window (function code: 18)
(Input/output is possible with only the ways listed above.)

Compensation data for straightness compensation at 128 points can be input/output in parameter format in
the same way as with stored pitch error compensation data. A straightness compensation point number
plus 20000 is the corresponding parameter number. (The format is the same as that for pitch error
compensation data.)

- 52 -

B-64483EN-1/03 1.AXIS CONTROL

Input/output of the compensation data for straightness compensation at 128 points is performed at the
same time as that of stored pitch error compensation data.

If straightness compensation at 128 points is used, a straightness compensation point number plus 20000
is the corresponding parameter number for stored pitch error compensation also.

1.3.8 Gradient Compensation

Overview

By compensating for those errors in tools such as feed screws that depend on the position of the machine
system in detection units, machining precision can be improved and mechanical life can be prolonged.
Compensation is performed along an approximate straight line formed with a parameter-specified
compensation point and a compensation amount related to it.

Explanation

Three approximate straight lines are formed with four parameter-specified compensation points and
compensation amounts related to the respective compensation points. Gradient compensation is carried
out along these approximate straight lines at pitch error compensation intervals. The gradient
compensation amount is added to the pitch error compensation amount.

Unlike stored pitch error compensation, whose amount is set up for an individual compensation point, an
amount of gradient compensation is calculated for individual compensation points by setting up four
typical points and compensation amounts for them.
Example:
In above figure, the compensation amounts at the individual compensation points located between

points a and b are (β-α)/(b-a).

Nos. 5871 to 5874 (compensation amounts at compensation points a to d for
individual axes) is changed, the compensation amount determined from the
compensation amount after the change is output after the point at which to
output the compensation amount for the next gradient compensation is passed.

6 Parameters must satisfy the following conditions:

- The compensation amount at a compensation point must be in the range of

-127 to 127.

- Compensation points must satisfy the following relationships: a≤b≤c≤d.

- Compensation points must be located between the most distant
compensation point in stored pitch error compensation on the - side of each
axis and the most distant compensation point on the + side. If all four points
are equal to 0, compensation is not performed.

7 To add the gradient compensation function option, the stored pitch error

compensation function option is required.

The number of compensation points located between the most distant

compensation point on the + side of each axis and the most distant
compensation point on the + side in stored pitch error compensation must not
exceed 1536.

1.3.9 Linear Inclination Compensation

Overview

While inclination compensation uses up to three approximate error lines, linear inclination compensation
uses one approximate error line to compensate the machine status change.
The approximate error line is formed with the slope and intercept of the straight line specified in
parameters.
This function performs compensation independently of other compensation functions such as pitch error
compensation, etc.

Changing a linear inclination compensation parameter

Linear inclination compensation parameters can be changed at any time.
If you want to change a linear inclination compensation parameter, follow the procedure below:
(1) Change the linear inclination compensation parameter from the PMC.

A linear inclination compensation parameter can be changed with the following methods in addition

to the PMC:

• Change the parameter with MDI operation.

• Change the parameter with programmable parameter input by the G10 command.

After the parameter is changed, the PMC sets the linear inclination compensation parameter change

demand signal TCHG to the logic level different from that of the linear inclination compensation

parameter change completion signal FTCHG.
(2) The CNC obtains the new linear inclination compensation parameter value in it since the logic level

of the linear inclination compensation parameter change demand signal TCHG is different from that

of the linear inclination compensation parameter change completion signal FTCHG.
(3) After obtaining the value, the CNC sets the linear inclination compensation parameter change

completion signal FTCHG to the same logic level as of the linear inclination compensation

parameter change demand signal TCHG. Obtaining the new parameter value is now complete.

NOTE

When the power is on, the CNC obtains the parameter setting in it regardless of

signal operation.

1.3.10 Bi-directional Pitch Error Compensation

Overview

In bi-directional pitch error compensation, different pitch error compensation amounts can be set for
travel in the positive direction and that in the negative direction, so that pitch error compensation can be
performed differently in the two directions, in contrast to stored pitch error compensation, which does not
distinguish between the directions of travel. In addition, when the direction of travel is reversed, the
compensation amount is automatically calculated from the pitch error compensation data to perform
compensation in the same way as in backlash compensation. This reduces the difference between the
paths in the positive and negative directions.

Pitch error compensation amount (absolute value) at the reference position
when the machine moves to the reference position in the direction opposite
to that of the reference position return

This example assumes that the direction of a manual reference position return is positive. For parameter
No. 3627, therefore, set -2, which is the pitch error compensation amount (absolute value) at the reference
position when the machine moves to the reference position in the negative direction.

- Compensation example

If, in the setting example given in the previous section, the machine moves

0.0 to 40.0,

40.0 to -40.0, and

-40.0 to 0.0
for a manual reference position return, pitch error compensation pulses are output as follows:

Machine coordinate

Compensation pulse

When the travel direction changes from positive to negative at the position of 40.0, the compensation for
the reverse of the travel direction is output.

pulse of -5 is the result of the following calculation:

The pitch error compensation positions are arranged with equal spacing. The space
between two adjacent positions is set for each axis. The minimum interval between pitch
error compensation positions is limited and obtained from the following equation:
Minimum interval between pitch error compensation positions = maximum feedrate/7500
Unit : mm, inch, deg or mm/min, inch/min, deg/min
Example:

When the maximum feedrate is 15000 mm/min, the minimum interval between pitch
error compensation positions is 2 mm.
