the MANUAL mode
Power-ON check
When power is supplied
to
the PGU, the power indication LED on the upper right hand side of the
PGU goes
ON.
This LED is
so
designed as to be turned
ON
by the built-in power regulator in the PGU.
If the LED fails to go
ON
when the power supply is connected, a hardware fault such as a broken
fuse caused by the contamination by foreign matter may have occurred.
Please consult your nearest Mitsubishi representative.

Program check
Mitsubishi recommends checking the programs and parameters stored in the PGU by using the
teaching panel
(TP).
When either a parameter or program is changed, it is absolutely necessary
to
check both the
parameter and program, as they are interrelated.
Program check
If
there is any error, it is necessary
to
change the program (see the error codes (PEO to
PEE) given
on
page 108).
Parameter check
