14. 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 time-out error (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 ABST, ABSB0, and ABSB1 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.
CN1 Pin No.
Output signal
ABS transfer mode (ABSM): OFF ABS transfer mode (ABSM): ON
22 Positioning completion ABS transmission data bit 0
23 Zero speed detection ABS transmission data bit 1
25 During torque limit control ABS transmission data ready
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 longer.
