[Home return status: Not complete]
● When the [ST0] signal is turned ON, home return operation begins.
● When the [ST1] signal is turned ON, as with the [ST0] signal, home return operation begins.
● Turning the ST signal OFF midway through home return operation will cause a gradual stop.
[Home return status: complete]
● When the ST signal is turned ON, the ELECYLINDER moves [Backward] and [Forward].
● While the ST signal is ON, operation will continue until the [Backward end] or [Forward end]
is reached.
● Turning the ST signal OFF midway through operation will cause a gradual stop.
→ For details, refer to "4.5 Operating method from master device".
Caution
If stopped when the LS or PE signals are not ON, the ELECYLINDER may be stopped
on the way to the backward or forward end, or it may have stopped at the backward or
forward end during pressing operation with no contact.
We recommend first inputting the [ST0] signal and then performing the following actions
after returning to the backward end.
If battery-less absolute specification (option) is selected, the home return complete
status is retained.
However, if the [Change home return direction] or [Adjust home position] parameters
are changed, home return status will be not-complete; perform homing (absolute reset).
→ For details, refer to "6.4 Parameter function descriptions".
