14. ABSOLUTE POSITION DETECTION SYSTEM 
 
14.7 Signal explanation 
When the absolute position data is transferred, the signals of connector CN1 change as described in this 
section. They return to the previous status on completion of data transfer. The other signals are as described in 
section 3.5. 
For the I/O interfaces (symbols in the I/O Category column in the table), refer to section 3.8.2.

mode 
ABSM 
(Note)

While ABSM is on, the servo amplifier is in the ABS transfer 
mode, and the functions of ZSP, TLC, and D01 are as 
indicated in this table. 
DI-1 
(Position

ABS request 
ABSR 
(Note) 
18 
Turn on ABSR to request the ABS data in the ABS transfer 
mode. 
DI-1 
ABS transmission 
data bit 0 
ABSB0 22 
Indicates the lower bit of the ABS data (2 bits) which is sent 
from the servo to the programmable controller in the ABS 
transfer mode. 
If there is a signal, D01 turns on. 
DO-1 
ABS transmission 
data bit 1 
ABSB1 23 
Indicates the upper bit of the ABS data (2 bits) which is sent 
from the servo to the programmable controller in the ABS 
transfer mode. 
If there is a signal, ZSP turns on. 
DO-1 
ABS transmission 
data ready 
ABST 25 
Indicates that the data to be sent is being prepared in the ABS 
transfer mode. At the completion of the ready state, TLC turns 
on. 
DO-1 
Home position 
setting 
CR 41 
When CR is turned on, the position control counter is cleared 
and the home position data is stored into the non-volatile 
memory (backup memory). 
DI-1 
Note. When "Used in absolute position detection system" is selected in parameter No.PA03, pin 17 acts as the ABS transfer mode 
(ABSM) and pin 18 as the ABS request (ABSR). They do not return to the original signals if data transfer ends.
