Read/ Instruction
Write code
Write HED Write the set frequency/speed into the RAM or EEPROM.
H0000 to HE678 (0 to 590.00Hz): frequency in 0.01Hz increments
(The display can be changed to the rotations per minute using Pr.37 and
HEE
Pr.144. (Refer to
• To change the set frequency consecutively, write data to the inverter
RAM. (Instruction code: HED)
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.
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.
Write HF4 H9696: Fault history is cleared.
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 details on 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 lock (refer to
Read H00 to H6B Refer to the instruction code
values as required.
When setting Pr.100 and later, the link parameter extended setting must

be set.
Read H7F Parameter settings are changed (extended) according to the settings.
For details of the settings, refer to the instruction code
