Parameter accessing error numbers
Number
Cause
Remedy
0 … 199:
Parameter access has been converted to a parameter channel request. Error
detected in the inverter. Additional information is in r2054.05 and r2054.06:
Parameter number, index word
0
Parameter number does not exist
Check data block number
1
Parameter number cannot be modified
--
2
Minimum/maximum not reached or exceeded
--
3
Sub-index does not exist
Check data block offset
4
Access of single value with array identifier
Set data block offset = 0
5
Access to word with double word request or vice
versa
Use correct data type
(e.g. INT for word, DINT for
double word)
6
Setting not allowed (resetting only)
--
7
Descriptive element cannot be modified
--
11
No status as master control
--
12
Key word missing
--
17
Request cannot be processed due to operating
state

--
102
Channel not wide enough
--
104
Illegal parameter value
--
106
Request not implemented
--
200/201
Modified minimum or maximum not reached or
exceeded.
Minimum or maximum can be
further limited in operation
