(extended)
Read H79
The states of the output signals such as forward rotation,
reverse rotation and inverter running (RUN) can be monitored.
(For the details, refer to page 5-653.)

Read
H6D
Read the set frequency/speed from the RAM or EEPROM.
H0000 to HFFFF: Set 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 5-341))

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 5-341))
To change the set frequency consecutively, write data to the
inverter RAM. (Instruction code: HED)

Inverter reset 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.
4 digits
(A, C/D)
H9966: Inverter reset
When data is sent normally, ACK is returned to the computer,
and then the inverter is reset.

4 digits
(A, C/D)
Parameter clear
All parameter
clear
Write HFC
All parameters return to initial values.
Whether to clear communication parameters or not can be
selected according to the data.
앫
Parameter clear
H9696: Communication parameters are cleared.
H5A5A: Communication parameters are not cleared.
앫
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 A-5.
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 5-215).
4 digits

Parameter
Read H00 to H63 Refer to the instruction code (page A-5) and write and/or read
parameter values as required.
When setting Pr. 100 and later, the link parameter extended
setting must be set.
