H0000 to H9C40: 0.01Hz increments (hexadecimal)
(0 ≠ 400.00 Hz)
To change the running frequency consecutively, write data to the
inverter RAM. (Instruction code: HED)
H9696: Resets the inverter.
As the inverter is reset on start of communication by the computer, the
inverter cannot send reply data back to the computer.
All parameters return to the factory settings.
Any of four different clear operations is performed according to the data.
