Double solenoid system "ST0", "ST1" signals: Movement command input (backward/forward)
The ST signal function automatically switches depending on whether the unit has completed home return or not.
Signal name | Signal abbreviation | Function overview by status | |
|---|---|---|---|
Home return: Not complete | Home return: Complete | ||
Backward | ST0 | Backward after home return operation | Backward |
Forward | ST1 | Forward after home return operation | Forward |
[Home return status: Not complete]
- When the "ST0" signal is turned ON, home return operation begins.
The actuator should move to the backward end after the home-return operation completes. - When the "ST1" signal is turned ON, as with the "ST0" signal, home return operation begins.
The actuator should move to the forward end after the home-return operation completes. - 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 moving part moves Backward or 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 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. - When the encoder is the incremental type, the condition after the power is rebooted should be in the home-return incomplete. Also, it is necessary to perform the homereturn operation (absolute reset) when parameters are changed in "Home-Return Direction Change", "Home Position Adjustment" as the condition of home-return should get to incomplete.
