Except where restricted by the drive, all parameters are available for both reading
and writing. The parameter writes are verified for the correct value, and for a valid
register addresses.
Note: Parameter writes through standard Modbus are always volatile i.e. modified
values are not automatically stored to permanent memory. Use parameter 1607
