Error Codes Section 12-4
Note For PCUs with unit version 1.2 or earlier, driver main circuit OFF errors can be
detected regardless of whether the axis is servo-locked. For PCUs with unit
version 1.3 or later, driver main circuit OFF errors will be detected only when
the axis is servo-locked and will not be detected when the axis is not servo-
locked.

input sig-
nal 3020 The origin
proximity input
signal could
not be
detected
within the
range of both
limit input sig-
nals during an
origin search. Check the origin proxim-
ity input signal wiring
and the signal's alloca-
tion setting in the Servo
Parameters. Check that
the dog width of the ori-
gin proximity input signal
is no shorter than the
communications cycle. Operation
stops
according
to the

After detecting
the origin
proximity input
signal during
an origin
search opera-
tion, a limit
input signal
was detected
before detect-
ing the origin
input signal. Check that the origin
input signal selection in
the PCU's Axis Parame-
ters is correct. When the
external latch signal is
selected as the origin
input signal, check the
external latch signal wir-
ing and the allocation
setting in the Servo
Parameters.
Limit input

ON 3021 The limit input
signal in the
origin search
direction has
already been
input during a
single-direc-
tion origin
search. Check the limit input sig-
nal wiring for the corre-
sponding direction and
check the limit input sig-
nal's allocation setting in
the Servo Parameters. Emer-

Parameters. Emer-
