7. Operation <Practical Steps>
7.2.2 Method Used When No HOME Input Signal Is Available (PIO Pattern = 5)
Since no home return signal (HOME) is available in PIO pattern 5, input the rear end move command (ST0) first
to perform home return.
x When the rear end movement command (ST0) turns ON, the actuator starts moving toward the mechanical
end on the home side.
Once the mechanical end is contacted, the actuator reverses its direction and moves to the home position,
stops temporarily at the home position, and then moves to the rear end.
x Once the home position is reached, the home return complete output (HEND) turns ON.
Caution: When performing home return, pay attention to the following:
[1] Confirm that no obstacle is present in the rear end direction.
[2] If any obstacle is present in the rear end direction, move the actuator toward the front
end and remove the obstacle. Issuance of the front end move command is permitted
for this reason. In this case, the actuator moves forward at the home return speed
and when the actuator reaches the mechanical end, the front end position complete
output (LS1) turns ON.
[3] Do not input the intermediate point move command (even if the command is input, it
will be ignored).
