Connecting an Absolute Encoder

You can get the position data from the absolute encoder with MECHATROLINK communications.
Therefore, it is not necessary to wire the PAO, PBO, and PCO (Encoder Divided Pulse Output) signals.
If they need to be wired, refer to the following section.

Structure of the Position Data of the Absolute Encoder

The position data of the absolute encoder is the position coordinate from the origin of the absolute
encoder.
The position data from the absolute encoder contains the following two items.
•
The number of rotations from the origin of the encoder coordinate system (called the multiturn data)
•
The position (number of pulses) within one rotation
The position data of the absolute encoder is as follows:
Position data of absolute encoder = Multiturn data
(setting of Pn212)+ Position (number of pulses) within one rotation.
For a single-turn absolute encoder, the multiturn data is 0.
