12. ABSOLUTE POSITION DETECTION SYSTEM

12.4 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.

Note. When "Used in absolute position detection system" is selected in [Pr. PA03], pin 17 acts as ABSM and pin 18 as
ABSR. They do not return to the original signals if data transfer ends.

pin No.
While ABSM is on, the servo amplifier is in the
(Note)
ABS transfer mode, and the functions of CN1-22,
ABSM
CN1-23, and CN1-25 are as indicated in this
17
table.
(Note)
Turn on ABSR to request the absolute position
ABSR
18 data in the ABS transfer mode.
Indicates the lower bit of the absolute position
data (2 bits) which is sent from the servo to the
ABSB0 22
programmable controller in the ABS transfer
mode. If there is a signal, D01 turns on.
Indicates the upper bit of the absolute position
data (2 bits) which is sent from the servo to the
ABSB1 23
programmable controller in the ABS transfer
mode.
Indicates that the data to be sent is being
ABST 25 prepared in the ABS transfer mode. At the
completion of the ready state, ABST turns on.
When CR is turned on, the position control
counter is cleared and the home position data is
CR 41
stored into the non-volatile memory (backup
memory).
