Origin Search Operation
Section 8-2
Note
(1) The Servo Drive’s origin proximity input signal (origin return deceleration
limit switch signal) must be allocated to execute ORIGIN SEARCH. The
forward/reverse rotation limit signal (forward/reverse drive prohibited sig-
nal) must be allocated to use a reversal mode. If these input signals are
not allocated, ORIGIN SEARCH cannot be executed properly. For details
on allocating Servo Drive input signals, refer to
6-4 Standard Settings for
Servo Drives Using MECHATROLINK
.
(2) Make sure that the external input signals for origin searches (limit input
signal and origin proximity input signal) maintain a signal width no shorter
than the MECHATROLINK communications cycle. If the input signal width
is shorter than the communications cycle, the PCU is unable to detect the
input signals, and operations cannot be performed normally.
(3) For origin searches, the origin signal is detected after the origin proximity
input signal (origin return deceleration limit switch) changes from ON to
OFF. Therefore, be sure to use a sensor for the origin proximity input sig-
nal, such as a photoelectric switch, that does not produce chattering.
Chattering from contact switches may result in the displacement of the or-
igin position.
1
Without origin proximity input
signal reversal
The origin input signal is
detected after the origin prox-
imity input signal turns ON.
This setting is possible only
for Position Control Units with
unit version 2.0 or later.
2
Not use origin proximity input
signal
The origin proximity input sig-
nal is not used.
The origin search operation is
started at the zero point return
approach speed 1.
If this setting is used along
with reversal mode 3, and axis
parameter check error (error
code: 3091) will occur when
the data is transferred.
This setting is possible only
for Position Control Units with
unit version 2.0 or later.
