Instruction
Code
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.
HFD
H9966: resets the inverter
When data is sent normally, ACK is returned to the computer and then the
inverter is reset.
HF4 H9696: clears the faults history as a batch
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.
Clear Type
Parameter clear
HFC
All parameter clear
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.
H00 to H63
Refer to the instruction code (Refer to page 58) and write and/or read
parameter values as required.
When setting Pr. 100 and later, link parameter extended setting must be set.
Data format of Pr. 37 read and write is E2 and A2
Parameter description is changed according to the H00 to H09 setting.
H7F
For details of the settings, refer to the parameter instruction code (Refer to
HFF
page 58).

H00: Frequency ∗2
H6C
H01: Parameter-set analog value
H02: Analog value input from terminal

Refer to the list of calibration parameters on the next page for calibration
parameters.

The gain frequency can also be written using Pr. 125 (instruction code: H99) or Pr.
126 (instruction code: H9A).
Available for writing 2 commands, and monitoring 2 items for reading data
