Diagnostics
The "Frequency error" is output as a process data if the max. frequency limit fmax applicable to the respective resolution range is exceeded, see chapter Position determination.
The "Amplitude error" is output as a process data if the voltage of the Sin/Cos signal is too small. This can, with suitable position, also be used for the detection of a wire break.
In CoE object 0xA000 "ENC Diag Data" these errors are counted and can also be read from the PLC via SDO access.
