Chapter 5 Operation
5.3 I/O Signals
5-23
ME0394-1A
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
Points of caution for when the workpiece is not struck (no contact) and the movement to forward
end or backward end is complete. Consider a master device sequence or detection method
based on the content below.
● If no contact is made, the PE signal will not turn ON.
A timer is required to determine if no contact has been made.
● After a non-contact operation, the unit will stop in the pressing operation status.
● If the workpiece shifts once pressing complete is determined and the PE signal is ON,
the ELECYLINDER will start another approach operation with the PE signal still ON. If the
workpiece cannot be pressed again, it will remain ON even with no contact.
