1 INTRODUCTION

The YASNAC J50M is a high-performance CNC for the simultaneous control of

2 or 3 axes of a driven machine, with emphasis placed on high-speed machin­ing, and programming capability.

FEATURES

1.

Ultra-high-speed Performance
“High-speed, computing system”
processor in the YASNAC J50M.

2.

Significant Downsizing (Miniaturized)
YASNAC J50M is significantly downsized because it has surface mounted
devices and customized gate arrays.

This manual explains both basic and optional features of YASNAC J50M as
well as the servo system.
You can determine your own hardware requirements after carefully reading
this manual.

is achieved by installing a 32-bit micro-

This manual is subject to change without

The feedrates programmed by F codes can be
modified between O% to 200% in 10% increments.

(3) Feedrate override cancel

When this switch is turned on, any feedrate
override ef feet is cancelled, and the tool moves

at the originally programmed feedrates.

2.17 PREPARATORY FUNCTIONS

G codes consisting of address G plus up to 3
digits, specify work for the respective blocks.
For details of the G codes, refer to Table 1.5 in

ranges by F codes.

(1) Ordinary G codes include non-modal G-codes

marked with*, and modal G-codes belonging to

groups 01 through 15.

2.18 ABSOLUTE/lNCREMENTAL
PROGRAMMING (G90/G91 )

With the following G-codes, the tool movement
can selectively be programmed either in absolute
values or in increments:

G90 :
G91: incremental designation

absolute designation

2.19 PROGRAMMING OF ABSOLUTE ZERO
POINT (G92)

With a command “G92 X... Y.. . Z. ..:,” an ab­solute coordinate system is established with the
current tool position having the specified coordi­nate values.

2.20 POSITIONING (GOO,G06)

(1] GOO X... Y... Z... ;

With this command, the tool moves at the rapid
traverse rate to the specified coordinate position,
moving independently in each coordinate direction.
The motion after positioning will be in the ERROR
DETECT ON mode. GOO is a 01 group modal G
code. The ERROR DETECT OFF mode can be

entered by parameters.

180”OR OVER

(2) G06 X... Y... z... ;

with this command, after executing. a positioning
similar to GOO, the program advances to the next
block in the ERROR DETECT OFF mode. G06 is
non-modal, and is effective only in the program­med block.

Note:

In the ERROR DETECT ON mode, the
command of the next block is executed only after
the servo-lag pulses in the current block are
reduced to a permissible number. The ERROR
DETECT OFF mode is where the command of the
next block is executed immediately after the dis­tribution of the pulses in the current block, re­gardless of the servo–lag pulses. In this mode,

the corners of the workplaces are slightly
rounded.

2.21 LINEAR INTERPOLATION (GOI)

GOI X... Y... Z... F... ;

With this command, the tool moves along the

specified straight line at a feedrate specified by
the F code.

2.22 CIRCULAR INTERPOLATION (G02, G03)

START POINT

G02 X... Y.., Rt... F... ;

(3) G02 (G03) I... J... F... Ln;

This command moves the tool around a
designated complete circle n times. When L is
not programmed, the tool moves only once
around the circle.

(4) G codes for plane designation (G17 to G19)

The plane for programming circular interpolation

is specified by the following G codes:

G17:
G18:
G19:

XY plane
2X plane
YZ plane

Note :

1. Circular interpolation is possible over two or
more quadrants.

2. Circular interpolation is also possible with

respect to the optional 4th linear axis.

2.23 DWELL (G04)

(1) G02 (G03) X... Y... I... J... F... ;

These commands move the tool along the speci­fied circular path at feedrate specified by the F
code.

X and Y specify the end point of the cir­cular motion, and I and J specify the center of
the circular path in XY plane. With the proper
selection of address, similar circular interpolation
is programmed also in the XY and ZX planes.
G02 is for clockwise motion, and G03 is for
counterclockwise motion.

(2) G02 (G03) X... Y... R... F... ;
Circular interpolation is also possible by desig-

nating the radius R with the above command.
When R > 0, a circular path with a center angle

smaller than 180° is programmed, and when R c
O, the center angle of the circular path is larger
than 180°.

G04 P...;

With this command, the tool remains motionless

for the duration of time specified by the P code.
The minimum and the maximum programmable
dwell times are 0.001 and 99999.999 seconds,
respectively.

2.24 EXACT STOP CHECK (G09, G61 , G64)

This function is effective only in the blocks of .

blocks are executed in the ERROR DETECT ON

mode until G64 is programmed.

In either output mode, spindle speed
override can be accomplished.
permits overrides by steps of 10% within a range
of 50 to 120% to the spindle output command.

Note:

1. When the power supply is turned on, the
status corresponding to G64, that is, the
ERROR DETECT OFF mode, is on.

2. Rapid traverse motion is controlled by GOO
and G06, and not influenced by these exact
stop G codes.

2.25 MISCELLANEOUS FUNCTION

are grouped in the following three categories:

Meaning

These G codes are non-modal, and are effective
only in the block in which they are programmed.
When circular interpolation is included in the
same block in which a tool position offset is pro–
grammed, the radius and the end point are ex­tended also.

In this case

~ proper compensation

for tool radius is possible only for machining
1/4, 3/4 and 414 circles.

2.30 OFFSET MEMORY

The two digits following the address H or D are
called tool offset numbers, and these numbers
are assigned to the 99 tool offset values stored
in the tool offset memory.

compensation command (specified by the H code)
or the tool position offset command (specified by
the D code among the stored values.

Note: The 99 tool offset values can also be used

with the tool radius compensation C function

(option).

Up to 299.

2.33 MANUAL FEED

Manual feed is possible in the following three

modes, simultaneously in all three axes.

The tool moves at the rapid traverse rate, in-

dependently in all three axes.

equipment (option) , to collate them with punched
cards, and store them from tape readers.
