Also the documentation mentions a parity bit... Not sure if this is present or not

Replacing the "e" with a "g" in the format string will convert the encoders Gray code to binary

So it only works properly after the encoder position changed?

A SSI encoder should always have a valid output

Yes, it has an error in that it gets a different encoder value when I turn on the encoder power.After reading this value, the LinuxCNC worked normally and produced no errors. 
thank you

LinuxCNC is reading the encoder 1000 times a second

When does the encoder value become correct?
