*2 When Use in the absolute position detection system is selected in the parameter No.PA03, the pin 17 is the ABS transmission mode
(ABSM), and the pin 18 is the ABS request (ABSR). The signals do not return to the original signals even after the data transfer is
completed.
For details on signals of the pin 17 and 18 while the ABS transmission mode is off and the input/output interface, refer to the manual for
the servo amplifier (MR-J4-A).

ABSM 17 While the ABSM is on, the servo amplifier is in the ABS transmission mode, and the CN1-22, 23,
and 25 functions are as shown below in this table.

ABSR 18 The ABSR is turned on when ABS data is requested in the ABS transmission mode.
ABSB0 22 This signal indicates the lower bit of the two bits of ABS data to be transferred from the servo
amplifier to the PLC system in the ABS transmission mode. The ABSB0 turns on when this signal
occurs.
ABSB1 23 This signal indicates the upper bit of the two bits of ABS data to be transferred from the servo
amplifier to the PLC system in the ABS transfer mode. The ABSB1 turns on when this signal
occurs.
ABST 25 This signal indicates that the ABS transmission data is ready in the ABS transmission mode.
When the data is ready, the ABST is turned on.
