Caution in "FWBW" Signal Input in Single Solenoid System
"FWBW" Signal is to be detected at edges. Therefore, operation would not be made if the state of "FWBW" Signal is the same as the direction of move when it becomes ready to receive an input signal.
When "FWBW" Signal is in ON state alike the forward movement in such a case as shown below, it is necessary to have the signal level set OFF once.
As the signal level OFF is a command to make a movement to the backward end, when positioning has not been conducted at the backward end, movement should be made in the direction to the backward end once and then to the forward end.

- At powering
- When alarm canceled with RES Signal after alarm generated
- When 24V drive cutoff released (for TMD2)
Also, when "FWBW" Signal is in OFF state alike the backward movement, it is necessary to have the signal level set ON once.
As the signal level ON is a command to make a movement to the forward end, when positioning has not been conducted at the forward end, movement should be made in the direction to the forward end once and then to the backward end.
