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.

2.1. ‘TAPEREADER
(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.

NOTE
Keep each door tightly closed at all times.

(b) After inspecting the control with dcor open, close the door and fasten door locks (2 per door) securely using the key provided (No. YEOOI). Whenopening or closing, insert the key all the way into the keyhole and turn until it clicks (approximately a quarter-turn). The key can be removed position.

(1)
(a)
The control panel is constructed as a dust­proof, sheet-steel enclosure with gasketed doors so as to keep off dust and oil mists.
2.3 ACSERVO!lOTOR
(1) Vibration and noise (Daily
Vibration can be checked by resting the hand
–8–
or as required)
on the motors, and for noise, using a listen-
ing stick is recommended.
If any abnormality
is found, contact maintenance personnel imme-
diately.
(2) Motor contamination and impairment (Dai
or as required)
Check the motor exterior visually. If dirt damage should be observed, inspect the motor
by removing the machine cover. Refer to the machine tool builder’s manual.
2.4 BATTERY
Make sure that ‘BAT”or ‘A/B” on the right-
low position of CRTscreen is not displayed.
If it is displayed, the battery must be
replaced within a month.
(6) With the power on, remove the old battery.
(7) Put the new bat tery in the holder and set
the connector.
See Fig. 2.4. Battery connec-
tion.

Whenreplacing, never remove the old battery
with power off, otherwise the data stored in memoryare cleared.
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.
(5) Check to see if lLED on memoryboard is
illuminated. Fig. 2.3 shows the arrangement
of LEDand the battery.
If illuminated,
replace the battery with new one.

This description covers the troubles displayed
by alarm codes that were recognized by diagnos-
tic function of NCunit during normal opera­tion.
Refer to Appendix 1
“List of Alarm Codes.”
Some additional explanations are given for
especially difficult troubles.
Display Method
If an alarm condition occurs, a display “ALM” or “A/B” (for battery alarm) blinks on the 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: Depress the (ALM)key This will cause up to 4 pairs of alarm codes
and alarm messages to appear in order of impor-
tance,
Note:
with the most serious one at the top.
In an alarm state, the alarm screen appears taking priority over any other display.
There is no need to operate

4.2.4 flLARtl179 (Temperature Alarm inside the Panel)
Cause of Trouble
Ambient temperature of CI)Umodule exceeded the specified value
(70”Ct3”C) by meas-
uring at top of CPS­10N as a result of fan failure.
Failure of power
supply unit(CPS-10N)
(Temperature detector
is built inside the
power supply unit.)
_——
Ambient temperature of NCpanel is too high.
(Applicable temperature
range is O-C to 40”C.)
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.
If the alarm still lights.
“ 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 cause of clogging and restart the operation.
The power supply unit must be NCplaced. Contact YASREP.
o Reduce the effects of
temperature rise by shielding the NCunit, etc.

4.2.5 ALARM231 AND232 (Zero Point Return Area Error)
Cause of Trouble
Zero point return start position was at zero point side rather
than at deceleration

Note that this error
check can be performed only after power
supply is turned OFFand the manual return to zero point has been completed.

Solution
Return it to the decelera-
tion LS or try the zero point return again from a more distant point.
