Diagnostics
The inverter provides many diagnostic parameters which are helpful for operation, mainte-
nance, error diagnosis, error correction, etc.
•
In the following overview the most common diagnostic parameters are listed. For the key-
pad you can find these diagnostic parameters in group 1.
•
Further parameters for more specific diagnostic purposes are described in the following
subchapters.
•
The diagnostic parameters can only be read and cannot be written to.
Parameter
Name / value range / [default setting]
Info
0x2030
CRC parameter set
•
Read only
Display of the checksum of the parameter set.
•
Each parameter set has an individual checksum (CRC32) that is cre-
ated from the settings of all storable indices (P-flag) of the parameter
set. If a setting changes, the checksum changes as well.
•
Cyclic redundancy check (CRC): By comparing the checksums of
parameter sets, you can check whether the parameter sets are identi-
cal or not.
