2.1.4 Safety Check for Factory Power Connections
Power wire check
Before supplying the power from the factory, visually check that the wire insulating sheath has no
damage nor degradation (crack, flaw and others).
Measurement of insulation resistance of the machine
Measure the insulation performance (insulation resistance) of the machine by following the procedure
shown below before connecting the factory power and make sure that it is 5 MW or more.
1. Prepare a measuring instrument of insulation resistance tester which has the capacity of DC500 V
(common name: megger).
2. Make measuring terminal of insulation resistance tester have short circuit and make sure that it is 0 W.
3. Turn ON the machine breaker, the external transformer breaker, the machine power switch, the
external transformer power switch and others.
4. Measure the insulation resistance between the machine power wire and the ground wire (PE wire).

=CHECK=
When the voltage regulator is connected between the machine and factory power, measure the
insulation performance of voltage regulator in the same way as the machine.
When the insulation performance is out of the criteria
1. Turn OFF the switch which is the farthest from the power side and check the change of the insulation
resistance.
2. Point out the position where the insulation resistance has a big change and check unit/wiring in detail.
Repair the wire if there are some faults.
3. When the problem persists even after re−wiring, component/unit may be defective. Exchange or repair
the component/unit.
Checks after factory power connection
1. Tell the customers to ask the electrical facility specialist (maintenance provider), who have a contract
with the customers, to measure the insulation performance.
Always shut OFF the machine
power switch before performing
wiring.
There is the possibility of
electric shock.

2.1.5 Safety Operation Check
DC power supply voltage check
1. Turn the power [OFF] and check the electric connections within the P783. (Make sure that they are
tight and without slack.)
2. Check the P783 DC power supply voltage with a tester.
=Specification=
Tolerance value : + 5V : + 5.00 to + 5.25V
+12V : +12.00 to +12.60V
−12V : −12.00 to −12.60V
+15V : +15.00 to +15.75V
−15V : −15.00 to −15.75V
3. Check the 24V voltage of optical module.
=Specification=
24V voltage : 23.5 to 25.5V
Safety limit operation check
1. Turn “SERVO MOTOR” on the main control panel [ON] and turn the power [ON].
2. Open the back side cover. (One of the lower covers)
=REMARKS=
There is AC servo driver.
3. Move the stage manually in the Y axis (+), (−) directions until it touches the mechanical stopper. Check
the ST axis driver must display the error No. ’38’.
4. Do the same adjustment to SQ axis (+), (−) directions , CY axis (+), (−) directions and CX axis (+), (−)
directions as the Y axis.
=HINT=
The machine must be turned [OFF] then [ON] to clear the error No.’38’ from the drivers between
the (−) and (+) limits.

1 block switch operation check
1. Open the front door and check the safety stop.
2. Select “START” on the main control panel and check if 1 block operation can be continued.
=HINT=
When checking (+), (−) limits operation (NC AXIS JOG movement), move the stage manually.
Return to origin and operate in NC AXIS JOG.
(+), (−) limit operation check
1. Check the machine is at origin.
=REFERENCE=
Refer to ’Operation Manual / Origin Return’.
2. Select ’NC AXIS JOG’ and check each axis (+) and (−) limits.
=CHECK=
Be sure to move the stage manually, and return to origin and then operate in NC AXIS JOG.
Emergency switch operation check
1. Insure that the power supply turns [OFF] when any of the emergency switches in 2 places on the
machine front and in 2 places on the machine rear are turned [ON].
