[8] Position 1 Operation Circuit
The main circuit is designed to process and manage signals “start” o “moving” o “positioning
complete” to move the actuator to position No.1.

If 1 is not pulsed, 3 is reset
with 4 turned ON and 2 is
turned ON again.
Position 2 start signal
If movement is completed,
the moving circuit is turned OFF.
Turned OFF at start of next positioning
to position No.2.
Because any of start, moving or completion is set to
ON, it is possible to know the state in which the
actuator is stopped if it occurs.
If movement is started (PEND is
turned OFF), the start circuit is turned OFF.
Without home return, positioning to
position No.2 takes place after
home return

Startup
• Circuit 10 is designed to start positioning to position No.1 again after positioning to position No.3
is completed.
• If the “Operation” lamp goes off, the operation circuit is reset entirely. When the “Stop” button is
pushed, the actuator will stop at completion of the operation being executed. At emergency
stop, the actuator is stopped immediately (which is the function of ERC3 and PIO Converter ).
