7-9-3 Coding Method
Select this method when the data format from the encoder is binary.
This method divides SSI data up into multi-turn data, single-turn data, and status data. The present
value of the encoder is then expanded to signed, 32-bit present value data from the multi-turn and sin-
gle-turn data according to the encoder resolution. This encoder present position and status data are
then both sent to the input area.
Additional Information
If the set value of the Encoder Resolution parameter is 0, the resolution is calculated as the
maximum value of the single-turn data plus 1.
