8 Parameter data transfer
The Inverter Drive 8400 protec (PROFIBUS) supports cyclic and acyclic transmission of
parameter data:
 Cyclic DP-V0 parameter data is based on the DRIVECOM profile.
If the parameter data channel is active according to DP-V0, it is assigned an additional
4 words of input / output data.
 Acyclic DP-V1 parameter data is based on the PROFIdrive profile.
8.1 Addressing of the parameter data
The parameter data are addressed via codes which are listed in a code table in this
documentation and in the corresponding documentation of your controller.

Addressing of the parameters for DP-V0 parameter data channel
In the case of the DP-V0 parameter data channel, the parameters of a device are not
addressed directly via Lenze code numbers, but via indexes (bytes 3 + 4) and subindexes
(byte 2).
 The conversion is made via an offset (24575 / 0x5FFF):
– PROFIBUS-Index
dec
= 24575 - Lenze code numbers
– PROFIBUS-DP index
hex
= 0x5FFF - Lenze code number
hex
 Example for C00105 (quick stop deceleration time):
– PROFIBUS-Index
dec
= 24575 - 105 = 24470
– PROFIBUS-DP index
hex
= 0x5FFF - 0x69 = 0x5F96
 The parameter values are entered into the user data (bytes 5 to 8) of the telegram.
