Data Description
Code
write
H6D Read set frequency/speed from RAM or
E²PROM.
H0000 to HFFFF: Set frequency in 0.01Hz
increments
Speed increments 0.001 (when Pr. 37 =
Read
0.01 to 9998)
H6E
When "0.01 to 9998" is set in Pr. 37 and
"01" in instruction code HFF, the incre-
ments change to 0.001 and the data format
is E2.
HED Write set frequency/speed to RAM or
E²PROM.
H0000 to H9C40 (0 to 400.00Hz):
Frequency increments 0.01Hz
Speed increments 0.001 (when Pr. 37 =
0.01 to 9998)
When "0.01 to 9998" is set in Pr. 37 and
Write
HEE
"01" in instruction code HFF, the incre-
ments change to 0.001 and the data format
is A2.
To change the set frequency consecutively,
write data to the inverter RAM. (instruction
code: HED)
H9696: Resets the inverter.
As the inverter is reset at start of communi-
cation by the computer, the inverter cannot
send reply data back to the computer.
Write HFD
H9666: Resets the inverter.
When data is sent normally, ACK is
returned to the computer and then the
inverter is reset.
H9696: Alarm history batch clear
Write HF4
All parameters return to the initial values.
Whether to clear communication parame-
ters or not can be selected according to
data. (✔: Clear, —: Not clear) Refer to Tab.
6-1 for parameter clear, all clear, and com-
munication parameters.
Write HFC
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.
