11. Operations
11.1 Return to origin position
Return to origin operation should be performed first in the following cases:.
(1) When power is applied for the first time.
(2) When the actuator or motor is replaced.
(3) When alarm
“
Group E
”
is cleared by applying the power again.
For (1) and (2), Alarm No.10-153
“
Absolute encoder ID Alarm error
”
is generated after the power is
applied, so perform the return to origin operation after resetting the alarm.
■Return to origin operation
The actuator moves in the return to origin direction (* this direction is dependent on the actuator) from the
initial position at the moment of power ON. Refer to (1) in the figure below.
When the actuator reaches the end of travel limit it pauses for a short time. The controller recognizes the
position as the end of travel limit of the actuator. Then, the actuator moves at a low speed in the direction
opposite to the return to origin direction: Refer to (2) in the figure below.
The position after the travel becomes the origin.
