Origin
search
Origin input
signal error
6202
There was an origin input signal
received while decelerating after
the origin proximity input signal
was received during an origin
search in mode 0.
Perform the following
adjustments so that
the origin signal will
turn ON after decelera-
tion is completed.
• Increase the dis-
tance between the
sensors used for the
origin input signal
and the sensor used
for the origin prox-
imity input signal.
• Decrease the origin
search high speed
and origin search
proximity speed set-
tings.
The axis where the ori-
gin input signal was
input will be deceler-
ated to a stop. Other
operating axes will not
be affected.
Limit inputs in
both direc-
tions
6203
Origin search cannot be executed
because there are limit signals
being input in both directions.
Perform the origin
search again after
checking the wiring
and signal type in the
axis parameters’ I/O
settings (N.C. or N.O.)
for both directions. If
the signal type is
changed, reset the
power supply or restart
the NC Unit before
resuming operation.
The origin search will
not be executed, but
other operating axes
will not be affected.
Simulta-
neous origin
proximity and
limit signals
6204
The origin proximity input and limit
signal in the origin search direc-
tion were input simultaneously
during the origin search.
Perform the origin
search again after
checking the wiring
and signal types in the
axis parameters’ I/O
settings (N.C. or N.O.)
for the origin proximity
and limit signals. If the
signal type is changed,
reset the power supply
or restart the NC Unit
before resuming oper-
ation.
An emergency stop
will be performed on
the axis where the sig-
nals were input. Other
operating axes will not
be affected.
