The Configuration of an Absolute System Using an Absolute Encoder
Connect the motor with absolute encoder and battery of absolute encoder, and setup the pa-
rameter Pr0.15 to 0 or 2（set abdolute encoder）,you can capture the exact prsent position
information after the power-ON.
Shift the system to origin once after installing the battery and clear the multi-turn data by
clearing the absolute encoder,then you can detect the absolute position without carrying put
homing operation.

Function
Select the use method of the absolute encoder.
0:Use as an absolute system (absolute mode).
1:Use as an incremental system (incremental mode).
2:Use as an absolute system (absolute mode), however
ignore the multi-turn counter over.
－
3:Use as an absolute system, however not use the
multi-turn counter (single-turn absolute mode).
4:Used as an absolute system (absolute mode), however
any upper limit value can be set for the multiturn
counter, and ignore the multi-turn counter over.
(continuous rotating absolute mode)
＊1 Battery for absolute encoder is required to
store the multi-turn data into the encoder.
Connect to either X4 or the junction connec-
tor between X6 and the encoder, when you
connect the battery. Do not connect to both.
