Faulty data in the encoder

This error occurs with new encoders, that have never been initialized
Solution: Initialize the data with the command HSAVE (terminal screen).

Extended error message S300 / S700 
a second error message with a small "i" (ERRCODE2) is displayed in the display, which has the following meaning:

i 16 Error while reading the BISS position in regsiter mode.
i 18 BISS communication fault
i 22 Reading the encoder data via slow data access was not possible (communication problem with the Encoder)
i 23 Reading the encoder data via fast data access was not possible (communication problem with the Encoder)
i 28 The plugged in option card does not match with the software version of the drive.
i 53 min. resolver amplitude (threshold) undershot
i 54 max. amplitude jump of the resolver signals
i 55 phase deviation between sine/cosine of the resolver
