3432

Range specification 6 of M codes that do not perform buffering (upper limit)

[Input type] Parameter input

[Data type] 2-word path

[Valid data range] 3 to 99999999

When a specified M code is within the range specified with parameter
Nos.3421 and 3422, 3423 and 3424, 3425 and 3426, 3427 and 3428,
3429 and 3430, or 3431 and 3432, buffering for the next block is not
performed until the execution of the block is completed.

NOTE

M00, M01, M02, and M30 are M codes that do not
perform buffering, regardless of parameter setting.

M98, M99, M codes for calling subprograms, and M
codes for calling custom macros are M codes that
performs buffering, regardless of parameter setting.

3441

Start number of M codes for which an M code group can be set (1)

3442

Start number of M codes for which an M code group can be set (2)

3443

Start number of M codes for which an M code group can be set (3)

3444

Start number of M codes for which an M code group can be set (4)

[Input type] Parameter input

[Data type] 2-word path

[Valid data range] 0, 100to99999999

Code numbers 0 to 99 on the M code group setting screen correspond
to M00 to M99. When adding M codes after the first 100 M codes,
specify a start M code number in these parameters. Thus, up to 400 M
codes can be added to the M code group setting screen in groups of
100 M codes starting with the set value. When 0 is set, no M codes are
added to the M code group setting screen.
When setting these parameters, follow the setting condition described
below. If the condition is not satisfied, no M codes are added to the M
code group setting screen as in the case where 0 is set.
(Setting condition)

The settings of parameters (1) to (4) (excluding the setting of 0)
must satisfy:

(1), (1)+99

(2), (2)+99

(39, (3) +99

[Data type] Bit path

# 0

AUP

The second auxiliary function specified in the calculator-type decimal

point input format, with a decimal point, or with a negative value is:
0: Disabled.
1: Enabled.
If the second auxiliary function is specified after setting this bit to 0,
the following operation results:
1. When a value is specified without a decimal point

A specified value is output onto the code signal without
modification, regardless of the setting of the calculator-type
decimal point input format (with bit 0 (DPI) of parameter No.
3401).

2. When a value is specified with a decimal point

The alarm (PS0007) is issued.

3. When a negative value is specified

The alarm (PS0006) is issued.

# 7

BDX

When ASCII code is called using the same address as the address for

the second auxiliary function (specified by parameter No.3460), this
parameter prevents the argument unit used when the option for the
second auxiliary function is selected from differing from the argument
unit used when the same option is not selected.
0: When bit 0 (AUP) of parameter No.3450 is set to 1, the argument

unit differs, depending on whether the option for the second
auxiliary function is selected or not.

1: The same argument unit is used. (The unit applied when the

option for the second auxiliary function is selected is used.)

[Example]

A setting is made so that address B is used to call O9004, and the
program O1 below is executed with parameter No.3460 = 66.

Second auxiliary function specification address

[Input type] Parameter input

[Data type] Byte path

[Valid data range] 65to67, 85to87

Specify which of A, B, C, U, V, and W is to be used as the address for
specifying the second auxiliary function. If an address used as an axis
name is specified, the second auxiliary function is disabled.

Name

A B C U V W

Setting value

65 66 67 85 86 87

Address B is assumed when a value other than the above is set.
However, the name U, V, or W can be used with the T series only
when G code system B or C is used. When a value from 85 to 87 is
specified with G code system A, the specification address for the
second auxiliary function is B.

Allowable difference between the specified end position and the end

position obtained from the increase/decrease and frequency in spiral

interpolation or conic interpolation

[Input type] Parameter input

[Data type] Real axis

[Unit of data] mm, inch (input unit)

[Minimum unit of data] Depend on the increment system of the applied axis

[Valid data range] 0 or positive 9 digit of minimum unit of data (refer to the standard

parameter setting table (B))
(When the increment system is IS-B, 0.0 to +999999.999)
This parameter sets the maximum allowable difference (absolute
value) between the specified end position and the end position
obtained from the increase/decrease and frequency in spiral or conic
interpolation.

Minimum radius needed to maintain the actual speed in spiral or conic

interpolation

[Input type] Parameter input

[Data type] Real path

[Unit of data] mm, inch (input unit)

[Minimum unit of data] Depend on the increment system of the reference axis

[Valid data range] (For IS-B and millimeter machines, 1.0 to 999999.999; for inch

machines, 1.0 to 99999.9999)
If this parameter value is 0 or a value outside the valid data range, the
minimum value of the range is assumed.
In spiral interpolation and conic interpolation, the speed is generally
held constant. In an area near the center, the spiral radius decreases,
resulting in an extremely high angular velocity. To prevent this, once
the spiral radius has reached the parameter-set value, the angular
velocity subsequently remains constant. As a result, the actual speed
decreases.
