Single Solenoid System
"Parameter No. 9 Electromagnetic Valve System" is to be set to "Single".
Home return operation/positioning operation: "FWBW", "LS0", "LS1" signals
Turning the "FWBW" signal ON when home return is not complete will first trigger home return operation.
After a momentary stop at the home position, it will then move to the backward end.
After a momentary stop at the home position, it will then move to the backward end.
- When the "FWBW" signal is turned ON, backward motion begins towards the mechanical end.
The movement speed is 20mm/s. - Once the mechanical end is struck, the direction will be reversed and forward motion will begin.
The unit will move forward until the home position, then stop. - After that, it will continuously move forward until the forward end, where it stops as operation is complete.
Caution
- In the home reverse specification (model: NM), home return operation is in the reverse direction.
This shows the PLC timing chart for operating the ELECYLINDER.
The basic process is as follows.
The basic process is as follows.
[Basic timing chart]
Δt1: Wait approximately 0.5 seconds from when the "*ALM" signal turns ON before inputting the first command.
Δt2: The time taken for the moving parts actually to reach the forward or backward end after the LS signal turns ON.
Consider Δt2 when giving instructions for the next operation from the PLC to the ELECYLINDER.
Δt2 becomes longer for larger detection ranges.
Δt2 also changes with the size of the transported load and acceleration/deceleration speeds.

Turn "FWBW" Signal OFF from the state of ON (turn it ON from the state of OFF) during operation and it starts decelerating and reverses, and then moves towards the backward (or forward) end.
For example, be careful of the following point with a large LS signal detection range.
For example, be careful of the following point with a large LS signal detection range.
If the sequence is set to turn the "FWBW" signal OFF immediately after the "LS1" signal turns ON, the ELECYLINDER may not have reached the forward end.
If the sequence is set to turn the "FWBW" signal ON immediately after the "LS0" signal turns ON, the ELECYLINDER may not have reached the backward end.
If the sequence is set to turn the "FWBW" signal ON immediately after the "LS0" signal turns ON, the ELECYLINDER may not have reached the backward end.
Caution
- Within the detection range, the LS signal turns ON even if the ELECYLINDER is mid-operation.
Pressing operation: "FWBW", "PE0", "PE1" signals
Before conducting pressing operation, refer to Pressing Operation Setting and configure the operating conditions and position settings using the Simple Data Setting screen.
The basic time chart is as follows.
[Pressing towards forward end]
[Pressing towards backward end]
Caution
- The pressing operation speed is 20mm/s.
- The workpiece remains pressed after the pressing is completed. If the workpiece moves or pushes back, it may be pressed even further.
- When the actuator hits a workpiece during approaching operation, any of alarm or pressing complete signal would be output but pressing operation should be continued.
The torque (current limit value) configured for "Pressing force" in the Simple Data Setting screen judges completion of pressing operation.
When the ELECYLINDER is performing pressing operation, satisfying the following conditions will produce a judgment of pressing complete, turning ON the PE signal.
"Accumulated time in which current has reached pressing value [%]" – "Accumulated time in which current is less than pressing value [%]" ≥ 255ms

Here are some caution for when operation to the forward end or backward end is terminated with a miss-pressing.
Consider a master device sequence or detection method based on the content below.
Consider a master device sequence or detection method based on the content below.
- PE Signal should not turn on when there is a miss-pressing. It is necessary to make a judgment whether miss-pressing was happened or not with using such a tool as a timer.
- After a miss-pressing, the pressing current should retain and positioning stop.
There may be an error occurred when an actuator is pushed back due to external force. - If the workpiece shifts once pressing complete is determined and the PE signal is ON, the ELECYLINDER will start another pressing operation with the "PE" signal still ON.
If the workpiece cannot be pressed again, it will remain ON even with no contact.
2-circuit power supply specification TMD2 (Option)
The 2-circuit power supply specification is capable of supply the motor power (drive source) and the control power individually.
Select the 2-circuit power supply specification (TMD2) when it is required to cut the drive power source off without keeping the control power supply to ELECYLINDER not turned off.
Refer to Pulse Motor Equipped Models Wiring , 24V AC Servomotor Equipped Models Wiring and 200V AC Servomotor Equipped Models Wiring.

ELECYLINDER should move at recovery from stop status when an actuator has stopped during movement to the forward end / backward end (out of LS signal detection range).
ELECYLINDER would not move even if recovered from stop status when an actuator has stopped at the forward end / backward end (inside LS signal detection range). When required to move it, turn "FWBW" signal on or off after recovery.
ELECYLINDER would not move even if recovered from stop status when an actuator has stopped at the forward end / backward end (inside LS signal detection range). When required to move it, turn "FWBW" signal on or off after recovery.
Warning
- ELECYLINDER should move at recovery from stop status when an actuator has stopped during movement to the forward end / backward end (out of LS signal detection range). Secure safety for the surrounding before recovery.
Here shows a timing chart for the case when an actuator has stopped during movement to the forward end / backward end (out of LS signal detection range).
- The absolute reset is to be completed already.
- It is to be a state of being at the backward end after the power is turned on.

Move to forward end (Cut of motor power supply during operation)

Note 1 A sudden stop should be made by the emergency stop torque.
When the drive power supply is cut off, it should come to "stop Signal: Motor voltage Drop" without generating an alarm.
