The index of the telegram is used to address the parameter or the Lenze code to be read or written:
Index = 24575 − Lenze Codestellennummer
• The index value is entered in flush left Intel format divided in a low and a high byte (see
example).
• For addressing a subcode, the number of the corresponding subcode must be entered in the
telegram subindex.
• Codes without subcodes always have the subindex “0”.
• The Lenze codes have an index between 40C0
hex
(16576) and 5FFF
hex
(24575):
Lenze code Index
dec hex
C0000 24575 5FFF
... ... ...
C7999 16576 40C0
Tip!
You can use the function L_FUNCodeIndexConv from theLenzeDrive.lib function library to
convert a code number into the corresponding index.
Example:
Addressing subcode 1 of code C0168 (error messages):
Index = 24575 − 168 = 24407 = 5F57
