7 ABSOLUTE POSITION DETECTION SYSTEM
7.3 Absolute position detection system by DIO [A]
Signal explanation
When the absolute value data is transferred, the signals of connector CN3 change as follows. On completion of data transfer,
the signal returns to the previous status.
Other signals do not change.
*1 When "Used in absolute position detection system" is selected in [Pr. PA03], pin 17 acts as ABSM and pin 18 as ABSR. They do not
return to the original signals even if data transfer is completed.

transfer mode. DI-1
ABS transmission data
bit 0 ABSB0 22 Indicates the lower bit of the absolute position data (2 bits) which is
sent from the servo to the programmable controller in the ABS transfer
mode. When there is a signal, ABSB0 is on. DO-1
ABS transmission data
bit 1 ABSB1 23 Indicates the upper bit of the absolute position data (2 bits) which is
sent from the servo to the programmable controller in the ABS transfer
mode. When there is a signal, ABSB1 is on. DO-1
ABS transmission data
ready ABST 25 Indicates ABS transmission data ready during ABS transfer mode.
When ready, ABST is on. DO-1
