6.4.9Mechanical Origin Search Function
1
）
Introduction
Mechanical origin search is the function of location and stop action (clamping)through the absolute position
memorized by absolute encoder.
Instructions:
1. After installing machine, set the mechanical origin firstly before servo drive is enabled
；
2. Using this function when workpieces need to return to initial position(mechanical origin)
；
3. In the state that motor shaft is connected with machinery;
4. Make sure servo drive is enabled and the battery is installed in the drive;
Set “mechanical origin” as initial position, the “mechanical origin” can be found in any position of
forward/reverse motion range set by servo motor. AL-27 alarm will alerts if exceeding the setting motion range.
See details in chapter 6.1.4.

Setting
Mechanical origin means that the physical origin position of machinery, which is also called initial position.
(1) Setting mode
a. Set current position as mechanical origin: After setting to the initial position of machinery, set So-48=1,
So-41=1, then
Current position is mechanical origin, the data of current position inputs Po136, Po138 automatically.
b. Set arbitrary point as mechanical origin: Set single-turn, multi-turn positions of encoder by Po136, Po138,
confirm mechanical origin.
【
Note
】
If using the mode of setting arbitrary point as mechanical origin to reset alarm when AL-24 alarm alerts,
set Po136, Po138 firstly, then set So-48=1, So-41=1, the alarm can be reset.
