Inverter reset Write HFD
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.
4 digits
(A, C/D)
H9966: resets the inverter
When data is sent normally, ACK is returned to the computer and then the
inverter is reset.
4 digits
(A, D)
Faults history batch
clear
Write HF4 H9696: clears the faults history as a batch
4 digits
(A, C/D)
Parameter clear
All clear
Write HFC
All parameters return to the initial values.
Whether to clear communication parameters or not can be selected
according to data. ( : Clear,
×
: Not clear)
Refer to page 58 for parameter clear, all clear, and communication
parameters.
When clear is executed for H9696 or H9966, communication-related
parameter settings also return to the initial values. When resuming
operation, set the parameters again.
Executing clear will clear the instruction code HEC, HF3, and HFF settings.
In the password locked status (refer to page 164) , only H9966 and
H55AA (all parameter clear) are valid.
∗1
Turning OFF the power supply while clearing parameters with H5A5A or H55AA
also clears the communication parameter settings back to the initial values.
