Data transfer

The master (e.g. a PLC) and inverter communicate with each other by exchanging data frames via

the fieldbus. The user data area of the data frame either contains network management data,

parameter data, or process data.
Different communication channels are assigned to parameter and process data in the inverter.
Parameters are for instance operating parameters, motor data, or diagnostic information, which are

stored under a code in the Lenze inverters.
Normally, the transfer of parameters is not as time-critical as the transfer of process data.

Access to the inverter codes

Via the communication module, a higher-level master (e.g. a PLC) can change the properties and the

response of each inverter integrated in the network.
In Lenze inverters, parameters to be changed are listed under codes.
Inverter codes are addressed via indexes when accessing the code through the communication

module.
The indexes for Lenze code numbers are between 16576 (0x40C0) and 24575 (0x5FFF).

- Lenze code number [hex]

Index = 24575 - 1 = 24574

Index = 0x5FFF - 0x1 = 0x5FFE
