Parameters supported by Modbus backwards

compatibility with legacy drives

ACx310/320/355 compatibility mode is a way to communicate with an ACxx80

drive in such a way that it looks like an ACx310/320/355 drive over Modbus RTU

or Modbus TCP. This mode can be enabled by changing parameter

Modbus mapping

In the ACx310/320/355 compatibility mode all supported parameters can be

read as if the drive were an ACx310/320/355. Some parameters are read only

and do not support writes. See the table below to see which parameters
