Low 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

(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:
