6.3 Parameter Assignment/Addressing

6.3 Parameter Assignment/Addressing
This section provides the following information for communication configuration and
programming:
● Drive parameter ID and corresponding communication protocol address
● Parameter tables:
– Network configuration parameters
– Network 1 configuration parameters
– Network 2 configuration parameters
● Pick list variable tables:
– Data from Drive variables
– Data to Drive variables
6.3.1 Correspondence between Drive Parameter ID and Communication Protocol
Address
The following table provides drive parameter IDs and the corresponding Profibus™ network
register. The following data is provided:
● Parameter ID
The drive parameter ID number to enter via the keypad or the ToolSuite.
● Profibus™ Network Data
Profibus™ uses a pre-defined byte count to communicate between the master and the
drive.
– The drive uses up to 136 bytes for input and output; 128 bytes are used to form the 64
– The data received (128 bytes) is mapped to the 64 data to drive registers and the data
– Network data size may be limited to 16, 32, 64, 96, 128, or 136 bytes for input and output
– Each network register is 16 bits (2 bytes). The order of the bytes can be swapped to
144
16-bit registers (2 bytes per register) and 8 bytes are 'reserved' for future use.
sent to the PLC is defined using the 64 data from drive registers.
using parameter 'Network 1 I/O Size' (9951) or 'Network 2 I/O Size' (9952). At 136 bytes,
only 128 are available to the user. You must configure the Profibus™ master to have
the same quantity of bytes.
match the network data format (9953, 9954).
