Refer to page 556 for data formats (A, A1, A2, B, C, C1, D, E, E1, E2, E3, F)

Turning OFF the power supply while clearing parameters with H5A5A or H55AA returns the communication parameter settings to the initial
settings.

Refer to the calibration parameter list below for details on calibration parameters.

The gain frequency can be also written using Pr.125 (instruction code: H99) or Pr.126 (instruction code: H9A).
Inverter reset Write HFD
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.
4 digits
(A and C/D)
H9966: Inverter reset
• After the computer correctly starts communication and send data to the
inverter, the inverter returns the ACK signal to the computer before being
reset.
4 digits
(A and D)
Fault history clear Write HF4 H9696: Fault history is cleared.
4 digits
(A and C/D)
Parameter clear
All clear
Write HFC
All parameters return to initial values.
Whether to clear communication parameters or not can be selected
according to the data.
• Parameter clear
H9696: Parameters including communication parameters are cleared.
H5A5A: Parameters other than communication parameters are cleared.

• All parameter clear
H9966: Parameters including communication parameters are cleared.
H55AA: Parameters other than communication parameters are cleared.

For the details of whether or not to clear parameters, refer to page 685 .
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
lock (refer to
page 253 ).
