ABB ACS560 - Parameters Supported by Modbus Backwards Compatibility with 550

372 Parameters
Parameters supported by Modbus backwards compatibility
with 550
ACx550 compatibility mode is a way to communicate with an ACx580 drive in such a
way that it looks like an ACx550 drive over Modbus RTU or Modbus TCP. This mode
can be enabled by changing parameter 96.78 550 compatibility mode to Enable.
In the 550 compatibility mode all supported parameters can be read as if the drive
were an ACx550. Some parameters are read only and do not support writes. See the
table below to see which parameters support writes.
