9 Parameter data transfer
The PROFIBUS communication unit supports the cyclic and acyclic transmission of
parameter data:
 Cyclic DP-V0 parameter data are based on the DRIVECOM profile.
If the DP-V0 parameter data channel is active, it additionally occupies 4 words of the
input and output data.
 The acyclic DP-V1 parameter data are based on the PROFIdrive profile (PROFIDrive (DP-
V1) in preparation)
9.1 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 Lenze parameters
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 indices (bytes 3 + 4) and subindices
(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 of 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.
