REMARKS
Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
For the instruction codes HFF, HEC and HF3, their values are held once written but cleared to zero when an inverter reset or all
clear is performed.
Example) When reading the C3 (Pr. 902) and C6 (Pr. 904) settings from the inverter of station 0

Code
H9696: Inverter reset
As the inverter is reset at start of communication by the
computer, the inverter cannot send reply data back to the
computer.
Write HFD
H9666: Inverter reset
When data is sent normally, ACK is returned to the computer
and then the inverter is reset.
Write HF4 H9696: Faults history batch clear
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 54 for parameter clear, all clear, and communication
parameters.
Clear Type
Parameter clear
Write HFC
All parameter clear
∗ Note that when using a three-phase power input specification model,
Pr.345 and Pr.346 are set back to initial values.
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.
Read H00 to H63 Refer to the instruction code (Refer to page 54) 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

The gain frequency can also be written using Pr. 125 (instruction code:
H99) or Pr. 126 (instruction code: H9A).
Inverter Send Data
ACK 00 Set "H01" to the expansion link parameter.
ACK 00 Set "H01" to second parameter changing.
STX 00 0000 ETX 25 C3 (Pr. 902) is read. 0% is read.
STX 00 0000 ETX 25 C6 (Pr. 904) is read. 0% is read.
