Modbus holding register addresses
Modbus holding register addresses for the ABB Drives profile and
DCU Profile
The table below shows the default Modbus holding register addresses for the drive
data with the ABB Drives profile. This profile provides a converted 16-bit access to
the drive data.
Note: Only the 16 least significant bits of the drive’s 32-bit Control and Status Words
can be accessed.
Note: Bits 16 through 32 of the DCU Control/Status word are not in use if 16-bit
control/status word is used with the DCU Profile.
