First step of troubleshooting
Perform the following check:
(1)
(2)
(3)
(4)
(5)
Power supply voltage should be
2OOV+:$,
50/60Hz,
or
21OV,
210V or
23OV+:gg.
.
In any case,
it should not go down below -15% of 200V.
o Check if the supply-voltage drops at a specific time
everyday.
o
Check if the supply voltage drops at start of a speci-
fic machine in the factory.
Are the peripheral control devices or functions in good
condition?
o Are the NC and programmable controller wired proper-
ly?
o Visually check cables and other components for condi-
tion.
Is temperature inside and outside the control equpment
below
55OC?
Visually check the control equipment.
o Cards,
circuit patterns, etc.
o Looseness of wire, damage, foreign matter, etc.
All control power supplies of IM-PW2 card meet the
specified voltages?
