9 Parameter data transfer
The E84AYCPM communication module 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 data
and the output data.
• Acyclic DP-V1 parameter data are based on the PROFIdrive profile.
9.1 Addressing of the parameter data
The parameter data are addressed via codes which can be found in this documentation and in the
corresponding documentation of your inverter.
Parameter reference
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-DP index
• PROFIBUS-DP index
Example of C00105 (quick stop deceleration time):
• PROFIBUS-DP index
• PROFIBUS-DP index
The parameter values are entered into the user data (bytes 5 to 8) of the telegram.
