5-5
Table 5-4 Parameter accessing error numbers
Number Cause Remedy
0 … 199: Parameter access has been converted to a PKW 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
--
101 Parameter number currently deactivated --
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
240 … 249: Parameter access is incorrectly formatted. Error detected on the PROFIBUS DP
Additional information in r2054.05 and r2054.06: Parameter number or S7 data block
number, sub-index or S7 data block offset.
240 Error in variable address (no additional
information)
Legal: “Data block” area
241 Data block number illegally formatted Legal: 1 … 31999
242 Data block offset illegally formatted Legal: 0 … 116
243 Illegal “type” Legal: CHAR, BITE, INT,
WORD, INT, DWORD, REAL
244 Illegal “Number of elements” on accessing
parameter value
Legal: Effectively 2 or 4 bytes
248 Illegal text/description modification --
249 Inconsistency in write request: “Type” and
“Number of elements” does not match “Data type”
and “Data length”
Error in communication device
250: Parameter access has been converted to a PKW request. Response from inverter is
seen as incorrect. Error detected on the PROFIBUS-DP. Additional information can
be seen in r2054.05 and r2054.06.
250 PKW response does not match request Error in the inverter
251: Error detected on the PROFIBUS-DP; no additional information
251 Response too long for response telegram Error in communication device
