Parameter access
The FI parameters cannot be directly accessed via the functions 03h, 06h or 10h, as many FI parameters have
array elements. Therefore, the addresses for NORD parameters are according to the following model:
Start address
Bit 15 – Bit 6
Bit 5 – Bit 0
Parameter number
Array Index
The lower 5 bits are available for the array elements, so that the maximum array size is 63. The parameter
values are shifted by 6 places.
Examples
 P102 Parameter set 1 = 0x1980
 P102 Parameter set 2 = 0x1981
 P510 Array element 2 = 0x7F81
NOTE
The description of the inverter parameters can be found in the main manual for the frequency
inverter (BU0500). However, parameters related to bus communication can also be found in
Section 1.8 .
