Code
Read H7B
H0000: Network operation
H0001: External operation
H0002: PU operation
Write HFB
H0000 to HFFFF: Output frequency in 0.01Hz increments
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
Read H6F HFF, the increments change to 0.001 and the data format is E2.
When "100" is set in Pr. 52, the monitor value is different
depending on whether the inverter is at a stop or running.
(Refer to page 154)
H0000 to HFFFF: Output current (hexadecimal) in 0.01A
Read H70
increments
H0000 to HFFFF: Output voltage (hexadecimal) in 0.1V

H01 to H3F: Monitor selection data
Refer to the special monitor No. table (page 228)
Write HF3
H0000 to HFFFF: Two latest fault records
Read H74 to H77
Refer to the alarm data table (page 229)
Write HF9
Control input commands such as the forward rotation signal (STF)
and reverse rotation signal (STR). (For details, refer to page 230)
Write HFA
Read H79
Monitor the states of the output signals such as forward rotation,
reverse rotation and inverter running (RUN). (For details, refer to
page 230)
Read H7A
Read set frequency/speed from RAM or EEPROM.
H6D
H0000 to HFFFF: Set frequency in 0.01Hz increments
Read Speed increments 1/0.001 (when Pr. 37 = 0.01 to 9998)
H6E 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 set frequency/speed to RAM or EEPROM.
HED
H0000 to H9C40 (0 to 400.00Hz): Frequency increments 0.01Hz
Speed increments 1/0.001 (when Pr. 37 = 0.01 to 9998)
Write 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.
HEE
To change the set frequency consecutively, write data to the
inverter RAM. (instruction code: HED)
