■Examples of Instance 101/151
Access the inverter parameter is enabled using byte 4 to 6 of this Instance.
Set the communication number of the parameter to byte 4, 5 (Index), and the value to byte 6, 7 (Data).
In case of the monitor parameter “FE**”, the value becomes "communication number - 0x7000 (same as bit14,
15 set to 0)".
① Read the parameter cmod (Command mode selection, communication number is 0003).
