Origin Return ８－３．
If the machine is operated by I/O signals, the motor can execute origin return by inputting
‘Origin Search’ signal. Also, the motor can execute origin return with User Program(GUI) and
DLL program.
The following table shows parameter types related to origin return.
Parameter Name
Description Range
Org Speed
Operation speed when origin return
starts
1~500,000[pps]
Org Search Speed
Low-speed operation speed after origin
sensor is sensed and operation start
speed when origin starts.
1~50,000[pps]
Org Acc Dec Time
The time assigned to the
acceleration/deceleration section when
origin return starts and stops.
1~9,999[ms]
Org Method To select how to return the origin 0~5
Org Dir
* 1
To select operation direction(CW or
CCW)
0~1
Org Offset
* 1
After origin return is finished, the motor
moves additionally as this setting value
and then stops.
-134,217,727 ~
134,217,727
Org Position Set
After origin return is finished, ‘Command
Pos’ value is set to this setting value. -134,217,727 ~
134,2177,27
Org Sensor Logic To set the origin sensor signal level. 0~1

The range differs from the product version, listed as below.
V06.01. 2 x.xx : -134,217,728 ~134,217,727
V06.01. 3 x.xx : - 2,147,483,648 ~ 2,147,483,647
(1) Origin Return method setting
To execute origin return, ‘Org Method’ parameter should be set as follows.

Arrow mark is for moving direction in below picture.

○ is origin end position in below pic..
(Numbers in ○ mark is indication the sensor Dog position or following example of origin
direction.)

Index Pulse is Z Phase

Origin return by Z Phase operates normally only when an external encoder is used.

In the case of origin return by a Z-pulse , after the completion of low speed origin return
in 'Org Search Speed' value, Z-pulse origin return (fixed rate) is done twice to complete
the return to origin with 10[pps] speed. (Fixed speed)
(It is method for precise return to Z-pulse origin.)

When limit sensor is detected, stop by the stop method set in H / W Limit Stop Method
(parameter No. 12, E-STOP / Stop) and then execute the remaining homing routine.
