[Operation of Slider Type/Rod Type Actuator]
1) With the ST0 signal being ON, the actuator moves toward the mechanical end at the home
return speed.
The moving speed is 20mm/s for most actuators but less than 20mm/s for some actuators.
Check the instruction manual of actuator.
2) The actuator is turned at the mechanical end and stopped at the home position. The
moving distance is the value set by Parameter No.22 “Home return offset level”. (Note 1)
Caution: In the home reverse specification, the actuator moves in the reverse direction.
Make sure to refer to Section 8.2 [18] when a change to Parameter No.22
“Home Return Offset Level” is required.
Note 1: It moves for the offset amount after the encoder Z-phase is detected.
[Actuator Movement for Spurious Absolute Type]
1) With HOME Signal ON, the actuator moves towards the home-return direction set in
Parameter No.5 at 3mm/s (fixed).
2) Move back and forth in approximately 16mm (to confirm the current position).
3) Home return operation is completed after the actuator confirms the current position.
� �
Caution: For Spurious Absolute Type, make sure to have a home return operation after
the power is turned ON or the software is reset.
B3 Error would be generated if there was an interrupting object in the
procedure of 2) and the current position could not be detected properly.
