48 10. Other Operation Functions
10.3 Origin Return
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 start.
1~50,000[pps]
Org Acc Dec Time
The time assigned to the acceleration/deceleration
section when origin return starts and sto ps.
1~9,999[ms]
Org Method To select how to return the origin 0~2
Org Dir To select operation direction (CW or CCW) 0~1
Org Offset
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
(1) Origin Return Method Setting
To execute origin return, ‘Org Method’ parameter should be set as follows.
① Common Origin (In case of ‘Org Method’= 0)
The machine moves up to the origin sensor by ‘Org Speed’ and ‘Org Acc Dec
Time’ parameters and then finishes precise origin return at the low speed set
to ‘Org Search Speed’. The machine senses the origin sensor and moves as far
as D1 and then stops. And the machine changes its moving direction and
additionally moves as far as D 2 and then stops. D1 and D2 are the same moving
distance. If Org Offset parameter is not ‘0’, the machine moves additionally
as much as the parameter (ex: D3) and then stops. If the limit sensor is sensed
while the machine is under origin return, the machine stops and reverses its
moving direction and then continu es to origin return operation.
