2 Set the Coding Method parameter.
You can change the count direction of data that is received from the encoder.
Set the Encoder Count Direction parameter to change the count direction.
If you set the parameter to use the opposite encoder count direction, the encoder present position is
calculated as shown below.

After the power supply is cycled, the initial position
is calculated as follows based on the position that
is first obtained from the encoder: Initial position =
Encoder resolution − Initial value.
