Turning OFF the power supply while clearing parameters with H5A5A or H55AA returns the communication parameter settings to the initial
settings.

The gain frequency can be also written using Pr.125 (instruction code: H99) or Pr.126 (instruction code: H9A).
NOTE
• Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
• For the instruction codes HFF, HEC, and HF3, their values once written are held, but cleared to zero when an inverter reset
or all clear is performed.

H9696: Inverter reset
As the inverter is reset at the start of communication by the computer, the
inverter cannot send reply data back to the computer.
HFD
H9966: Inverter reset
When data is sent normally, ACK is returned to the computer, and then the
inverter is reset.
HF4
H9696: Batch clearing of fault records
All parameters return to initial values.
Whether to clear communication parameters or not can be selected
according to the data.
• Parameter clear
H9696: Communication parameters are cleared.
H5A5A: Communication parameters are not cleared.
• All parameter clear
H9966: Communication parameters are cleared.
HFC
H55AA: Communication parameters are not cleared.
For the details of whether or not to clear parameters, refer to
When a clear is performed with H9696 or H9966, communication related
parameter settings also return to the initial values. When resuming the
operation, set the parameters again.
Performing a clear will clear the instruction code HEC, HF3, and HFF
settings.
Only H9966 and H55AA (all parameter clear) are valid during the password
