 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).

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,
Pr.144 and Pr.811. (Refer to page 357))
• To change the set frequency consecutively, write data to the inverter
RAM. (Instruction code: HED)

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
• When data is sent normally, ACK is returned to the computer, and then
the inverter is reset.

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: Communication parameters are cleared.
H5A5A: Communication parameters are not cleared.

• All parameter clear
H9966: Communication parameters are cleared.
H55AA: Communication parameters are not cleared.

For the details of whether or not to clear parameters, refer to page 711.
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 269).
