3-7-1 Origin Search
Note If the OFF position of the origin proximity signal (ORG) is close to the motor sensor’s Z-phase
3-42
When a motor with an incremental encoder/resolver is used, an operation to establish the mechanical
origin after the power has been turned ON is required. This operation is called “origin search.”
The origin search operation establishes the mechanical origin by actually operating the motor and uti-
lizing the limit input signals (CCWL/CWL), the origin proximity signal (ORG), and the motor sensor’s
Z-phase signal.
When an absolute encoder is used, origin search is not required because the absolute-value data is
retained by the battery even when the Driver’s power supply is turned OFF. (Origin compensation and
origin teaching are enabled.)
There are three origin search patterns, according to the position from which the origin search is begun.
Function
position, the origin position may deviate due to inconsistency in the origin proximity OFF position
(one revolution for U/H-series motors, and 1/2 revolution for M-series motors). If that occurs,
remove the motor from the mechanical system and adjust the Z-phase position. Then reinstall the
motor.
Pattern 1: When the origin search is executed between the limit input signal input in the reverse of
the origin search direction and the origin proximity signal input.
Pattern 2: When the origin search is executed while the origin proximity signal is ON.
Pattern 3: When the origin search is executed between the origin proximity signal input and the
limit input signal input in the origin search direction.

Operational Sequence
Z-phase output is 1 pulse per revolution, so rotate motor shaft for 1/2 revolution.
Z-phase output is 1 pulse per revolution, so rotate motor shaft for 1/2 revolution.
Z-phase output is 2 pulses per revolution, so rotate motor shaft for 1/4 revolution.
