 Modbus register addresses for the ABB Drives classic profile
The table below shows the Modbus register addresses for the drive data with the
ABB Drives classic profile. This profile provides a converted 16-bit access to the drive
data.
Note: Only the least significant 16-bits of the drive 32-bit Control and Status words
can be accessed.
Register Address Register Data (16-bit)
400001 Fieldbus Control Word (CW). See section Control Word for the ABB
Drives profiles on page 322.
400002 Fieldbus reference 1 (REF1)
400003 Fieldbus reference 2 (REF2
400004 Fieldbus Status Word (SW). See section Status Word for the ABB
Drives profiles on page 324.
400005 Fieldbus actual value 1 (ACT1)
400006 Fieldbus actual value 2 (ACT2)
400007 Fieldbus data in/out 1 (Drive parameter 58.35 Data I/O 1)
……
400030 Fieldbus data in/out 24 (Drive Parameter 58.58 Data I/O 24)

…409999 Register address (16-bit drive parameter) = 400000 + 100 × group +
index
Example: Modbus register address to drive parameter 03.18 is
400000 + 100 × 3 + 18 = 400318
Drive parameter access (32-bit drive parameter) = 420000 + 200 ×
group + 2 × index
Example: Modbus register address to drive parameter 01.27
420000 + 200
× 1 + 2 × 27 = 420254
