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.

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
Servo
Drive's
specified
stop
method for
limit inputs.
(The PCU
executes
EMER-
GENCY
STOP.)
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
already
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.

3022
Origin search
cannot be
executed due
to limit input
signals being
input in both
directions.
Check the limit input sig-
nal wiring in both direc-
tions and check the limit
input signal allocation
settings in the Servo
Parameters.
