3.8 I/O Signal Controls and Function
170
[7] Absolute Reset (conducted for Absolute Type)
When the power to the machine is turned ON for the first time (actuator operation), perform the
Absolute Reset.
1) Absolute Encoder Failure Detection Error is issued at the power-on.
2) Turn RES Signal (IN2) ON or reset the alarm in the alarm screen on a teaching tool such as
the PC software.
3) Issue the movement command to perform a home-return operation.
[8] Point-to-Point Movement = Operation Timing for Operation Patterns 0 to 2
(1) Single Solenoid System:
When the ST0 is turned “OFF”, the positioning to the backward end is performed and when
the ST0 is turned “ON”, the positioning to the forward end is performed.
Movement signal (ST0)
Backward end position detection output (LS0)
Backward end point positioning completion output (PE0)
Forward end point positioning completion output (PE1)
Forward end position detection output (LS1)
Actuator operation
Backward end Forward end Backward end
Positioning width
(Parameter No.1)
Positioning width
(Parameter No.1)
(2) Double Solenoid System:
With the combination of ST0 and ST1, the actuator performs a positioning at the target
position.
Forward end movement signal (ST1)
Backward end movement signal (ST0)
Backward end position detection output (LS0)
Backward end point positioning completion output (PE0)
Forward end point positioning completion output (PE1)
Forward end position detection output (LS1)
Actuator operation
Backward end Forward end Backward end
Positioning width
(Parameter No.1)
Positioning width
(Parameter No.1)
(Note) (Note)
(Note) When having a movement command, make sure to turn OFF both ST0 and ST1
before issuing a movement command to the target position.
If it is set to the continuous operation type in the initial setting, and both ST0 and
ST1 are turned OFF during a movement, the actuator decelerates and stops on
the spot.
If both ST0 and ST1 turn ON during a movement, the signal that came ON first
becomes effective.
