Set frequency (RAM)
Read
H6D
Read set frequency/speed from RAM or
E²PROM.
H0000 to HFFFF: Set frequency in 0.01 Hz incre-
ments
Speed increments 1/0.001 (when Pr. 37 = 0.01
to 9998)
When "0.01 to 9998" is set in Pr. 37 and "01" in
instruction code HFF, the increments change to
0.001 and the data format is E2.

Write
HED
Write set frequency/speed to RAM or E²PROM.
H0000 to H9C40 (0 to 400.00 Hz):
Frequency increments 0.01 Hz
Speed increments 1/0.001 (when Pr. 37 = 0.01
to 9998)
When "0.01 to 9998" is set in Pr. 37 and "01" in
instruction code HFF, the increments change to
0.001 and the data format is A2.
To change the set frequency consecutively,
write data to the inverter RAM. (instruction

6 Inverter reset Write HFD
H9696: Resets the inverter.
As the inverter is reset at start of communica-
tion by the computer, the inverter cannot send
reply data back to the computer.

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

8 All parameter clear Write HFC
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 Tab. 6-1 for
parameter clear, all clear, and communication
parameters.
When all parameter clear is executed for H9696
or H9966, communication-related parameter
settings also return to the initial values. When
resuming operation, set these parameters
again.
Executing clear will clear the instruction code
HEC, HF3, and HFF settings. In the password
locked status only H9966 and H55AA (all
parameter clear) are valid.
