[12] Commanded Position No. Output Circuit
Depending on the result of the ready circuit, this circuit converts position No. to the binary code
and outputs the data from PLC to PCON.

Set this signal to be 2 to 4 times as
long as PLC scanning time so that it
is turned ON after position No. is output
securely. (The PCON input condition is
defined to turn the signal ON after 6msec.)
Each of 2 , 5 , and 8 signals is turned OFF if the actuator is
started by start signal. It is because PEND it turned OFF to turn
the moving circuit, a main circuit, ON. (Handshake)
