Absolute Encoder Origin Offset
If using the absolute encoder, the positions of the encoder and the offset of the machine coordinate system
(APOS) can be set. Use Pn808 to make the setting. After the SENS_ON command is received by MECHA-
TROLINK communications, this parameter will be enabled.
<Example>
If the encoder position (X) is set at the origin of the machine coordinate system (0), Pn808 = X.
