Table Operation
• Opening operation
When the open signal is set to ON from OFF, the system decelerates and stops opening operation (  
above).
After deceleration stop, the system performs as follows in accordance with the status of the open signal 
(INT0) and close signal (INT1).
- Close signal (INT1) = OFF:The system starts closing operation (  above).  
(The system starts to move toward target address 2 at operation speed 2.)
- Close signal (INT1) = ON, open signal (INT0) = ON: The system remains stopped in the stopped 
position.
- Close signal (INT1) = ON, open signal (INT0) = OFF:The system starts opening operation.
(The system starts to move toward target address 
1 at operation speed 1.)
• Closing operation
When the close signal is set to ON from OFF, the system decelerates and stops closing operation (  
above).
After deceleration stop, the system performs as follows in accordance with the status of the open signal 
(INT0) and close signal (INT1).
- Open signal (INT0) = OFF:The system starts opening operation (  above).
(The system starts to move toward target address 1 at operation speed 1.)
- Open signal (INT0) = ON, close signal (INT1) = ON: The system remains stopped in the stopped 
position.
- Open signal (INT0) = ON, close signal (INT1) = OFF:The system starts closing operation.  (The system 
starts to move toward target address 2 at  
operation speed 2.)
