15. ABSOLUTE POSITION DETECTION SYSTEM
1) The ready (RD) is turned ON when the ABS transfer mode (ABSM) is turned OFF after
transmission of the ABS data.
While the ready (RD) is ON, the ABS transfer mode (ABSM) input is not accepted.
2) Even if the servo-on (SON) is turned ON before the ABS transfer mode (ABSM) is turned ON,
the base circuit is not turned ON until the ABS transfer mode (ABSM) is turned ON.
If a servo alarm has occurred, the ABS transfer mode (ABSM) is not received.
The ABS transfer mode (ABSM) allows data transmission even while a servo warning is
occurring.
3) If the ABS transfer mode (ABSM) is turned OFF during the ABS transfer mode, the ABS
transfer mode is interrupted and the ABS time-out warning (AL.E5) occurs.
4) The functions of output signals such as ZSP, TLC, D01, and INP change depending on the
ON/OFF state of the ABS transfer mode (ABSM).
Note that if the ABS transfer mode (ABSM) is turned ON for a purpose other than ABS data
transmission, the output signals will be assigned the functions of ABS data transmission.
