The data above means to change the set frequency (F00.07) to 50.00Hz, which will
take effect immediately, but will not be saved in EEPROM. After rewriting, inverter runs
at the frequency 50.00 Hz, but runs at the frequency set prior to change after inverter is

12.3.3.60x10 Write multiple registers or commands
This function code is used to write continuous register blocks (1 to 16 registers) in a
remote device.
The value requested for writing is described in the request data field. Each register
divides the data into two bytes
The normal response is to return the function code, the initial address and the
number of registers written.
