4.5 Operating method from master device
Home return operation/positioning operation: [ST0] [LS0] [ST1] [LS1] signals
Turning the [ST0] signal ON when home return is not complete will first trigger home return operation. After a
momentary stop at the home position, it will then move to the backward end. As well, when the [ST1] signal is
turned ON, the unit will move to the forward end after home return operation. However, for battery-less absolute
encoder specification, the positioning operation should be conducted without having the home return operation.
(1) When the [ST0] signal is turned ON, backward motion begins towards the mechanical end. The movement speed is
20mm/s.
(2) Once the mechanical end is struck, the direction will be reversed and forward motion will begin.
The unit will move forward until the home position, then stop.
(3) After that, it will continuously move forward until the backward end, where it stops as operation is complete.
Caution
In the home reverse specification (model: NM), home return operation is in the reverse
direction.
