3. Operation
[10] Reciprocating Operation between 2 Points ••• PIO Pattern 5
Reciprocating operation is performed continuously between the forward and backward positions while
ASTR signal is ON.
Once ASTR signal is turned OFF, the actuator positions at the current target position and stops.
[11] Pressing Operation ••• All PIO Patterns
If the pressing force and pressing band is set in the position data and perform a movement operation,
the actuator performs a pressing movement towards the target position. The following shows the
pressing operation towards the forward position as an example.
Movement Signal (ST0, ST1, ST2)
Backward Positioning Completion Output (PE0)
Forward Positioning Completion Output (PE1)
Actuator Operation
Refer to the timing chart of each PIO pattern for the movement signal
Pressing Complete Target Position
Pressing Band
Note:
For the pressing operation, use the positioning complete signal (PE*).
Even the operation
fi nishes with a miss-pressing and reaches the end point, PE* signal will turn ON. Set
the pressing band wider when miss-pressing detection is required and identify with a timer.
