Table 9.Parameter mapping
Register addresses, which are not allocated to any drive
parameter or data set, are invalid. Attempting to read from or write
to such an address will make the Modbus/TCP interface return an
exception code to the controller.
Refer to the drive manuals for drive-specific information such as
the data sets supported, and parameter numbers. Data set
registers are updated in a cyclic interval. Updating of parameter
registers happens at a slower interval.
