Origin Search Operation
Section 6-4
Operation Mode
The origin mode parameters determined the I/O signals used for origin
search. The I/O signals used for each mode are given in the following table.
Note
Specify mode 3 when using a Servo Drive with an origin adjustment function.
Set the operation according to the driver used and the application.
Note
There are drivers for stepping motors that can output positioning completed
signals in the same way as Servo Drives. It is possible to set modes 1 or 2 if
this kind of driver is used.
Origin Search Operation
The following 4 modes are available for origin search operation.
Operation

I/O signals
Operation when origin
is detected during
deceleration from
origin search high

Origin input signal
(selected using the
origin detection method
parameter)
Error counter reset

Positioning completed
input
0
Origin is determined by
detecting the rising edge
of the origin input signal.
Not used.
Not used.
After the origin has been
detected, origin search
operation is terminated.
The origin input signal
during deceleration is
detected. An origin input
signal error (error code
6202) will be generated,
and operation will decel-
erate to a stop.
1
Turns ON for 20 ms when
origin is detected.
The origin input signal
during deceleration is not
detected. Operation is
stopped and the origin is
determined when the ori-
gin input signal is
received after the origin
search proximity speed
has been reached.
2
After the origin has been
detected, origin search
operation will not be ter-
minated until a position-
ing completed input
signal has been received
from the driver. (The
Busy Flag will stay ON
during this time.)
3
The origin is detected at
the driver using the Servo
Drive’s origin adjustment
function. The origin input
signal at the PCU is not
used. Mode 3 cannot be
used with drivers that do
not have the origin
adjustment function.
Used as output for the
origin adjustment com-
mand.
Because origin detection
is not carried out at the
PCU, this situation does
not arise.

0
Servo Drive (see note)
Use this mode to reduce the operating
time applications where a high degree of
positioning accuracy is not required. (The
positioning completed signal at the Servo
Drive is not used.)
1
Use this mode for a high degree of posi-
tioning accuracy. (The positioning com-
pleted signal at the Servo Drive is not
used.)
2
Use this mode for a Servo Drive with an
origin adjustment function.
