6.2 Configuration of the controller (master)
The controller (master) must be configured before communication with the communication
module is possible.
Configuration for the controller (master) and the DP-V0 parameter data channel
For configuring the PROFIBUS you must read the device description file of the communication
module into the master.
The device description file for the E84AYCPM communication module (PROFIBUS) can be found in
the Download area at:
www.Lenze.com
The following language variants of the device description file can be used:
• LENZ0A89.GSD (source file, English)
• LENZ0A89.GSG (German)
• LENZ0A89.GSE (English)
Defining the user data length
The user data length is defined during the initialisation phase of the master.
The Inverter Drives 8400 support the configuration of a maximum of 16 process data words (max.
32 bytes). The optional activation of the cyclic parameter data channel additionally occupies 4
process data word (8 bytes).
The user data lengths for process input data and process output data are the same.
Description of the device data base file
Example of selecting the device data base file
• "Drivecom-PAR (cons)" = DP-V0 parameter data channel (4 words)
• "PCD (8W cons)" = 8 process data words
