[Operation of Slider Type/Rod Type Actuator]
1) If ST0 Signal gets turned ON when the home-return operation is incomplete, 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) If ST0 Signal gets turned ON when the home-return operation is incomplete, 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.
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.
