6 Parameter setting
The parameter setting of the 2131 module is subdivided into:
Controller parameters, which can also be set with the 8201BB or 9371BB keypad.
2131 parameters, which can only be accessed via the 2131 fieldbus module.
Only the controller parameters are permanently saved in the corresponding controller.
In the following, you will only find parameters which are important for the serial communication. For
further information on parameter setting of the controllers see the Manual 93XX or the Operating
Instructions of the corresponding controller.
The PROFIBUS-DP transmits two different types of data between the host and the controllers.
Parameter, e.g. operation parameters, diagnostic information, motor data.
In general, the transmission of parameters is not as time-critical as the transmission of the
second group of process data, but there is a larger data volume.
Process data, e.g. setpoints and actual value, which must be exchanged within a minimum
of time.
The data volume is small (e.g. 2 words with DRIVECOM or Lenze), which are to transmitted
cyclically.
For these two different tasks the transmitted data is divided into two logical communication
channels:
Parameter channel for the transfer of parameters
Process-data channel for fast transfer of process data. Process data are cyclically
transferred. Thus, the latest input and output data are constantly exchanged between the
host and the controllers.
6.1 Parameters
The system distinguishes two parameter types: the Lenze parameters which are implemented into
the Lenze controllers, and the DRIVECOM parameters. This chapter gives a short description of the
two parameter types and their relation to each other.
6.1.1 Lenze parameters
In general, the Lenze parameters of the Lenze controllers are addressed via the Lenze codes. For
detailed information about the Lenze parameters and their value ranges, see the Operating
Instructions of the corresponding controllers.
Lenze codes
In these Operating Instructions Lenze codes are identified with L-Cxxxx, to ensure that they are not
mixed up with the DRIVECOM index (e. g. L-C0001 for the Lenze code C0001).
Lenze code addressing
The access to Lenze parameters is possible. However, the addressing of the parameters (code
numbers) is shifted and calculated as follows:
Index = 24575 - LENZE_CODENR
Index
hex
= 5FFF
hex
- LENZE_CODENR
hex
The index for Lenze code numbers is between 20576 (5060hex) and 24575 (5FFFhex).
Example:
The Lenze parameter L-C0001 (operating mode) can be accessed via the PROFIBUS-DP under
index 24574 (= 24575 - 1).
