Additional Information
For a multi-turn encoder, the SSI Input Unit will perform gray code conversion treating the
multi-turn data and single-turn data as continuous data. In this case, always set the Encoder
Resolution parameter to 0. If you set the Encoder Resolution parameter to any value other than
0, the encoder present position will not be calculated correctly.
 Corresponding Gray Codes and Binary
The following table lists the gray codes and their equivalent values in binary.
 Remainder Gray Code
For single-turn encoders, if the set resolution is not a power of 2, remainder gray codes are used for
calculations.
