Origin Search Examples
Operation Connect a Servo Driver and execute an origin search based on the Servomo-
tor's built-in encoder phase-Z signal and a Origin Proximity Input Signal.
Conditions • Operating mode: 1
(Uses the Servomotor encoder's phase-Z signal as the Origin Input Sig-
nal.)
• Origin search operation setting: 0
(Sets reverse mode 1. Reverses direction when the limit input signal is
input in the origin search direction.)
• Origin detection method: 0
(Reads the Origin Input Signal after the Origin Input Signal goes
OFF→ON→OFF.)
• Origin search direction: 0 (CW direction)

0206 •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.
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.

Error
0300 The Servo Driver's Positioning
Completed Signal does not
come ON within the Positioning
Monitor Time specified in the
PLC Setup.
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.
