Parameters ...

• for instance are set for one-time system settings or if materials are changed within a machine;

• are transmitted with a low priority.

In the case of Lenze inverters, the parameters to be changed are contained in codes.

Indexing of the Lenze codes

If they are accessed via a communication module, the codes of the inverter are addressed by the

index.

The index of Lenze code numbers within the manufacturer-specific area of the object directory is

between 8192 (0x2000) and 24575 (0x5FFF).

Structure of a mailbox datagram

Mailbox data are transmitted in a datagramm within an EtherCAT frame. The data area of the

mailbox datagram has the following structure:

Conversion formula

Index [dec] Index [hex]

24575 - Lenze code 0x5FFF
