8.6 Encoder diagnostics
The diagnostic function allows you to perform a basic functional check of the
encoders. For absolute encoders with EnDat interface, the messages from the
encoder and its functional reserves are displayed. For incremental encoders

encoders, you can initiate further actions for more detailed testing or repair.
The PWT 101 or PWM 21 from HEIDENHAIN provides further inspection
and testing capabilities.
