Likely cause
During an origin search in oper-
ating mode 0, the Origin Input
Signal was received during the
deceleration started after the
Origin Proximity Input Signal
was received.
The origin search cannot be per-
formed because the limit signals
for both directions are being
input simultaneously.
The Origin Proximity Input Sig-
nal and the Limit Input Signal in
the search direction are being
input simultaneously during an
origin search.
•When an origin search in one
direction is being performed,
the Limit Input Signal is already
being input in the origin search
direction.
•When a non-regional origin
search is being performed, the
Origin Input Signal and the
Limit Input Signal in the oppo-
site direction (from the search
direction) are being input simul-
taneously.
•When an origin search with
reversal at the limit is being per-
formed, the Limit Input Signal in
the search direction was input
while the Origin Proximity Input
Signal was reversing.
•When an origin search with
reversal at the limit is being per-
formed and the Origin Proximity
Input Signal is not being used,
the Limit Input Signal in the
search direction was input
while the Origin Input Signal
was reversing.
The Servo Driver's Positioning
Completed Signal does not
come ON within the Positioning
Monitor Time specified in the
PLC Setup.
Corrective action
Take one or both of the following
steps so that the Origin Input
Signal is received after deceler-
ation is completed.
•Increase the distance between
the Origin Proximity Input Sig-
nal sensor and Origin Input Sig-
nal sensor.
•Decrease the difference
between the origin search's
high speed and proximity
speed settings.
Check the wiring of the limit sig-
nals in both directions as well as
the PLC Setup's Limit Signal
Type setting (NC or NO) and
execute the origin search again.
Turn the power supply OFF and
then ON if the signal type setting
was changed.
Check the wiring of the Origin
Proximity Input Signal and the
Limit Input Signal. Also check
the PLC Setup's Origin Proxim-
ity Input Signal Type and Limit
Signal Type settings (NC or NO)
and then execute the origin
search again. Turn the power
supply OFF and then ON if a
signal type setting was changed.
Check the wiring of the Limit
Input Signal and the PLC
Setup's I/O settings. Also check
the PLC Setup's Limit Signal
Type setting (NC or NO) and
then execute the origin search
again. Turn the power supply
OFF and then ON if the signal
type setting was changed.
Check the installation positions
of the Origin Proximity Input Sig-
nal, Origin Input Signal, and
Limit Input Signal as well as the
PLC Setup's I/O settings. Also
check the PLC Setup's Signal
Type settings (NC or NO) for
each input signal and then exe-
cute the origin search again.
Turn the power supply OFF and
then ON if a signal type setting
was changed.
Adjust the Positioning Monitor
Time setting or Servo system
gain setting. Check the Position-
ing Completed Signal wiring,
correct it if necessary, and then
execute the origin search again.
