Data Description
Code
write
H6D
Read the set frequency/speed from the
RAM or EEPROM.
H0000 to HFFFF: Set frequency in 0.01Hz
Read increments
H6E
Speed in 1r/min increments
(When Pr. 37 = 1 to 9998 or Pr. 144 = 2 to
10, 102 to 110)
HED
Write the set frequency/speed into the
RAM or EEPROM.
H0000 to H9C40 (0 to 400.00Hz): fre-
quency in 0.01Hz increments
H0000 to H270E (0 to 9998): speed in
1r/min increments
Write
HEE
(when Pr. 37 = 1 to 9998 or Pr. 144 = 2 to
10, 102 to 110)
To change the running frequency consecu-
tively, 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.
Any of four different all clear operations are
performed according to the data:
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.
Refer to the instruction code of the parame-
Read H00 to H63
ter list (appendix) and write and/or read the
values as required.
When setting Pr. 100 and later, link param-
Write H80 to HE3
eter expansion setting must be set.
