H0000 to H9C40: 0.01Hz increments (hexadecimal)
(0 ≠ 400.00 Hz)
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 on start of communication by the computer, the
HFD
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.

When all parameter clear is executed for H9696 or H9966,
communication-related parameter settings also return to the factory
settings. When resuming operation, set the parameters again.
