Communication Function
Multiple Holding Register Read or Write [17h]
Writes into or reads from consecutive multiple registers.
Example) Write 50,00 Hz into Output Frequency Setting (F001) of the Inverter with
Slave Address "1," and Read Output Frequency Monitor Value (d001).
(Register address) = (Register number) − 1
(Register address) = (Register number)
− 1
0000 1388h
→ 5000d → 50.00 Hz
0000 1388h → 5000d → 50.00 Hz
