Low byte High byte
The addressing of the parameter or of the Lenze code which is to be read or written is effected via
the index of the telegram:
Index + 24575 * Lenze code number
·
The value for the index is to be entered divided into a low and a high byte in the left−justified
Intel format (see example).
·
If a subcode is to be addressed, enter the number of the respective subcode in the subindex
of the telegram.
·
For codes without subcodes, the subindex always receives the value "0".
·
The index for Lenze codes is between 40C0
hex
(16576) and 5FFF
hex
(24575).

Tip!
For converting a code number to the corresponding index, the function L_FUNCodeIndexConv in
the LenzeDrive.lib function library is provided to you.
Example:
Subcode 1 of code C0168 (fault messages) is to be addressed:
Index + 24575 * 168 + 24407 + 5F57
