Single solenoid system "FWBW" signals: Movement command input (backward/forward)
The "FWBW" 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 | ||
Forward/Backward | FWBW | Forward/backward after home-return operation | Forward/Backward |
[Home return status: Not complete]
- When the "FWBW" signal is turned ON, home return operation begins.
It makes a movement forward after the home-return operation is completed. - Turn "FWBW" signal OFF during the home-return operation and it makes a movement backward after the home-return operation is completed.
[Home return status: complete]
- When the "FWBW" signal is turned ON, the moving parts moves Forward.
When the "FWBW" signal is turned OFF, the moving parts moves Backward. - While the signal is ON, operation will continue until the "Forward end" is reached.
While the signal is OFF, operation will continue until the "Backward end" is reached. - Turn "FWBW" signal OFF during the home-return operation and it decelerates and reverses to the backward operation.
Turn "FWBW" signal ON during the home-return operation and it decelerates and reverses to the Forward operation.
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.
It is recommended to turn "FWBW" signal first to set it back to the backward end, and then move on to the next operation. - For the incremental type, it is necessary to perform the home-return operation as it gets to the condition home-return incomplete once the power is rebooted. Also, for the battery-less absolute type, when a parameter change such as "home-return direction change" and "home position tuning", the home-return condition gets incomplete. Perform the absolute reset.
