(2) Unsuccessful pushing operation (Idling)
If pushing is not completed when the actautor moves from the start position until the actuator's
end, it is pushed back at the actuator end and the completion signal is generated.
(3) Workpiece moves when pushing operation is completed
(i)
When the actuator is in a pushing move
and the pushing force is greater than the
reaction force, the actuator will continue
to move to the end of stroke and then
output a signal.
(ii) The workpiece moves toward the opposite of the pushing direction (The reaction force of the
workpiece is too large and the actuator is pushed back)
When the actuator is pushed back after the pushing move is completed the actuator is pushed
until the reaction force and pushing force are balanced in the direction that the pushing started.
(Completion signal stays ON) An alarm is generated when the actuator is pushed back farther
than the start position of pushing. (Pushing failure)
