This Modbus request is used to write a number (No. of Registers) of adjacent words 
starting at a given address (Starting Address). The values to be written are supplied one 
after another (First Register Data -> Last Register Data).

 As for the EEPROM parameter, first the data is written to RAM, after that the data is written to 

EEPROM. Some EEPROM parameters cannot be changed during the inverter is running. 
When write to EEPROM parameter that will change inverter status from stop to run, the inverter must 
be in the state that it cannot run. 
For example: To write to EEPROM, the inverter must open ST-CC. (display shows "OFF") 
If not, the data is only written to RAM. 

 The Life of EEPROM is approximately 100,000 times. Avoid writing a command more than 100,000 

times to the same parameter of the Inverter.   

 Please access only parameters in document.
