Cause
In the orientation
operation using an
encoder,
5 V power is
not supplied to the
encoder.
Check
o
Disconnect the connector CONE
which is connected to the en-
coder and check that
5V
power
is applied between the pin 4
(or pin 5 or 6) and pin 20.
(See Appendixes l-7 and l-8).
o
Check the position of the
shortcircuit ring of the pin.

When 5 V power is applied,
replace the cable which is
connected from the CONB to
the orientation encoder with
a new one.
