Parameter number
Parameter numbers < 2000 PNU = parameter number.
Parameter numbers ≥ 2000 PNU = parameter number - offset.

Indexed parameters
For indexed parameters, you must write the index number as hex value into the sub-index
(IND bit 7 ... 0).
Parameter contents
Parameter contents can be parameter values or connector parameters. For connector
parameters you need two words. For interconnecting connector parameters please see
section: Interconnecting signals in the inverter (Page 315).
Enter the parameter value in the parameter channel right-justified as follows:
 8-bit values:
 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:
 Drive object of the connector parameter:
 The index or bit field number of the connector parameter:
116
Write the parameter number into the PNU (PKE bit 10 ... 0).
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).
