and stop is decremented by one. When the power is turned on, the setting

of the sequence number is 0.

D Exceptional blocks

If the predetermined sequence number is found in a block in which all

commands are those to be processed within the CNC control unit, the

execution does not stop at that block.

Example

D PARTS TOTAL

This value is incremented by one when M02, M30, or an M code specified

by parameter 6710 is executed. This value cannot be set on this screen.

Set the value in parameter 6712.

D PARTS REQUIRED

It is used for setting the number of machined parts required.

When the “0” is set to it, there is no limitation to the number of parts.

Also, its setting can be made by the parameter (No. 6713).

D PARTS COUNT

This value is incremented by one when M02, M30, or an M code specified

by parameter 6710 is executed. The value can also be set by parameter

6711. In general, this value is reset when it reaches the number of parts

required. Refer to the manual issued by the machine tool builder for

details.

D POWER ON

Displays the total time which the power is on. This value cannot be set

on this screen but can be preset in parameter 6750.

D OPERATING TIME

Indicates the total run time during automatic operation, excluding the stop

and feed hold time.

This value can be preset in parameter 6751 or 6752.

D CUTTING TIME

Displays the total time taken by cutting that involves cutting feed such as

linear interpolation (G01) and circular interpolation (G02 or G03). This

value can be preset in parameter 6753 or 6754.

D FREE PURPOSE

This value can be used, for example, as the total time during which coolant

flows. Refer to the manual issued by the machine tool builder for details.

D CYCLE TIME

Indicates the run time of one automatic operation, excluding the stop and

feed hold time. This is automatically preset to 0 when a cycle start is

performed at reset state. It is preset to 0 even when power is removed.

D DATA and TIME

Displays the current date and time. The date and time can be set on this

screen.

Explanations

D Usage

When the command of M02 or M30 is executed, the total number of

machined parts and the number of machined parts are incremented by one.

Therefore, create the program so that M02 or M30 is executed every time

the processing of one part is completed. Furthermore, if an M code set

to the parameter (No. 6710) is executed, counting is made in the similar

manner. Also, it is possible to disable counting even if M02 or M30 is

executed (parameter PCM (No. 6700#0) is set to 1). For details, see the

manual issued by machine tool builders.

Restrictions

D Run time and part count

Negative value cannot be set. Also, the setting of “M” and “S” of run time

(2) Perform a cycle start operation in the MEM mode to run the program.

The data will be stored in the tool life data area of the memory; at the

-999.999 to 999.999

-99.9999 to 99.9999

IS-C

-999.9999 to 999.9999

-99.99999 to 99.9999

Special B-axis offsets are input or output together with usual offsets.

When the option for tool geometry and wear compensation is provided,

wear offsets and geometry offsets can be specified separately. A tool

offset consists of both the specified wear offset and geometry offset.

In two-path control, tool offsets can be specified for each tool post or both

tool posts, depending on the setting of COF, bit 0 of parameter No. 8242.

If pitch error compensation data is specified, pitch errors of each axis can

be compensated in detection unit per axis.

Displaying and Setting

Pitch error compensation data is set for each compensation point at the

Pitch Error

intervals specified for each axis. The origin of compensation is the

Compensation Data

reference position to which the tool is returned.

The pitch error compensation data is set according to the characteristics

of the machine connected to the NC. The content of this data varies

according to the machine model. If it is changed, the machine accuracy

is reduced.

In principle, the end user must not alter this data.

Pitch error compensation data can be set with external devices such as the

Handy File (see Chapter III-9). Compensation data can also be written

directly with the MDI panel.

The following parameters must be set for pitch error compensation. Set

the pitch error compensation value for each pitch error compensation

point number set by these parameters.

In the following example, 33 is set for the pitch error compensation point

at the reference position.

Bidirectional pitch error

The bidirectional pitch error compensation function allows independent

compensation

pitch error compensation in different travel directions. (When the movement

is reversed, compensation is automatically carried out as in a backlash.)

To use this function, specify pitch error compensation for each travel

direction, that is, separately for the positive and negative directions of a

movement.

When using bidirectional pitch error compensation (setting the BDP bit

(bit 0 of parameter 3605) to 1), specify the following parameters in

addition to the pitch error compensation parameter.

D Number of the pitch error compensation point at the negative end (for

travel in the positive direction, for each axis): Parameter 3621

D Number of the pitch error compensation point at the positive end (for

travel in the positive direction, for each axis): Parameter 3622

D Number of the pitch error compensation point at the negative end (for

travel in the negative direction, for each axis): Parameter 3626

D Number of the pitch error compensation point at the positive end (for

travel in the negative direction, for each axis): Parameter 3627

Procedure for displaying and setting the pitch error compensation data

Set the following parameters:

D Number of the pitch error compensation point at the reference

position (for each axis): Parameter 3620

D Number of the pitch error compensation point having the smallest

value (for each axis): Parameter 3621

D Number of the pitch error compensation point having the largest

value (for each axis): Parameter 3622
