4. Operation
This shows the PLC timing chart for operating the ELECYLINDER.
The basic process is as follows.

Timing chart Remarks
1 Power Power ON
24 V DC power supply is
turned ON.
Turn ON the motor drive DC
power supply PSA-200 next.
2 Output * ALM
Turns ON if no alarm has
been triggered.
3 Input ST1
Moves to the forward end.
4 Output LS1
Moved to the forward end.
5 Input ST0
Moves to the backward
end.
6 Output LS0
Moved to the backward
end.
7
After this, "3" to "6" repeat.
Δt1: The time taken for the ELECYLINDER actually to reach the forward or backward end after the
LS signal turns ON. Consider Δt1 when giving instructions for the next operation from the PLC
to the ELECYLINDER.
Δt1 becomes longer for larger detection ranges.
Δt1 also changes with the size of the transported load and acceleration/deceleration speeds.
