Parameter number
Parameter numbers < 2000
PNU = parameter number.
Write the parameter number into the PNU (PKE bit 10 ... 0).
Parameter numbers
≥ 2000
PNU = parameter number
- offset.
Write the parameter number minus the offset into the PNU
(PKE bit
10 … 0).
Write the offset in the page index (IND bit 15 … 8).

Indexed parameters
For indexed parameters, you must write the index as hex value into the subindex (IND
bit 7 … 0).
Parameter contents
Parameter contents can be parameter values or connector parameters. You require two
words for connector parameters. You can find more information on interconnecting
connector parameters in the operating instructions of the Control Unit in the section
"Interconnecting signals in the inverter".
Enter the parameter value in the parameter channel right-justified as follows:
•
8-bit values:
Low word, bits
0 … 7,
bits 8
… 15 are zero.
•
16-bit values:
Low word, bits 0 … 15,
•
32-bit values:
Low word and high word
Enter a connector parameter right-justified as follows:
•
Number of the connector parameter:
High word
•
Drive object of the connector parameter:
Low word, bits 10 … 15
•
The index or bit field number of the connector parameter:
Low word, bits 0 … 9
