1. OUTLINE

The YASNACLX3provides you with an internal
self-diagnosis function (DGN). System mainte­nance can easily be accomplished with DGNand
other main functions as listed below;

(1) Microprocessor always monitors the machine
operations internally and can display the
status with function keys. IF any failure
occurs, NCimmediately stops with the blinking
of alarm displays. Also the same precedure

Feel by hand, and do

the audible inspection.
Inspect visually.

See if alarm for BATTERY

is displayed on CRTscreen.

Except for those checks which can be made with
the NCin the energized state, such as checks
for external cleanliness, vibration, and noise, tor’s station is not sufficient, because after
be sure to turn off the power supply to the NC
before starting to undertake routine mainte-

nance service.

For this, turning off the power supply by

pushing the POWEROFF button on the NCopera-

this button is pushed, still several areas in
the housing are energized, and are potentially

dangerous.

(1) [Cleaning the tape reader head (Dai

(a) Removetape rubbish and dust from the
glass with a blower brush. If the glass is
stained with oil or oily dust, wipe it using
agauze or soft cloth with absolute alcohol.
Also clean the tape guide and the tape
retainer.

(b) Remove the dust, if any, on LED (light

source) on top with a blower brush.

(2) Cleaning of tape tumble box (Weekly)

Clean the braided nylon leading tape with a
clean, soft cloth.

(3) Lubricating of tension arm shaft

Fo:r the control with 6-inch or 8-inch diameter

reels, lubricate the shaft end of tension arm,

when the tension arm does not move smoothly.

Replacing Procedure

(1) Depress POWEROFFpushbutton to shut off

the power supply to the operator’s station.

(2) Open the frent door of the control. The
battery of the memory (printed circuit) board
can be seen on the CPUmodule which is mounted
on rear of the front door.

(3) Where the control is equipped with a door

interlock switch, pull it out by hand. The

power can be turned on, with the door open.

(4) Depress POWERONpushbutton.

Some additional explanations are given for

especially difficult troubles.

Display Method

If an alarm condition occurs, a display “ALM”

bottom line of the CRTscreen regardless of

the mode or function.

In this case, detailed

information of the alarm condition will be
displayed by the following operations:

uring at top of CPS­10N as a result of fan
failure.

Failure of power

Check Method

.

Open NCpanel door and ensure that the

fan runs normally.

.

Ensure that air comes out of exhaust
port at the cooling duct.

Ensure that air intake port of cooling
duct is not blocked,

“ Turn OFF power supply, open the door

of NCpanel and cool it for about
30min.

“ Measure the ambient temperature.
“ The temperature may rise if NCpanel

is exposed to direct rays of the sun.

Solution

o Replace the fan if

faulty.
Call our service person­nel YASRllP.

● If cooling duct is

clogged, remove the

Servopack failure

Check Method

.

Check for looseness and removal of
MB20board’s connectors CN1 (X-axis),
CN2(Z-axis), CN3(spindle) and/or
CN4(spindle PG).

.

Check looseness and removal of
Servopack connectors.

—

This type of alarm results when main
power is applied though result of check

for above item 1 is normal.

Shorting plug connector to CN4at CPU
module is required for such specifica-

tions without spindle PG.

● Check if

occur at motor stop.

“ If alarm occurs above the speed to

Solution

● Correct looseness and/or

removal of connectors.
