Position error at startup on AD2S1210

I have strange issues with AD2S1210.

Sometimes, at startup,  there is a 180° error on the position from resolver. As this position is used to control a motor, this one rotate in wrong direction.

This is very bad for us because the application doesn't support rotation in wrong direction.

There is about 80m of cable between the AD2S1210 board and the motor/resolver, so we activate the 360° lock range on the AD2S.

The application produce lot of noise on signals, so the inputs are a little filtered.


From where this error could come from ?


Thank you
