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.
If the servo-on (SON) is turned OFF, the reset (RES) is turned ON, and the emergency stop
(EMG) is turned OFF during the ABS transfer mode, 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.
Output signal

ABS transfer mode (ABSM): OFF
ABS transfer mode (ABSM): ON
(Note)
D01
CN1B-4
Positioning completion
ABS data bit 0
ZSP
CN1B-19
Zero speed
ABS data bit 1
TLC

INP
CN1A-18
Positioning completion
ABS data bit 0
Note. CN1B-4 and CN1A-18 output the same signals. (To enter the positioning completion signal into INPS of the A1SD75,
connect CN1A-18.)
5) The ABS transfer mode (ABSM) is not accepted while the base circuit is ON
For re-transferring, turn OFF the servo-on (SON) signal and keep the base circuit in the off state
for 20ms or more.
