HEE
To change the running frequency consecutively, write data to
the inverter RAM. (Instruction code: HED)
H9696: Resets the inverter.
As the inverter is reset at start of communication by the
computer, the inverter cannot send reply data back to the
computer.
Write
HFD
H9966: Resets the inverter.
When data is sent normally, ACK is returned to the computer
and then the inverter is reset.
