Instruction
Code
H0000: Network operation mode
H0001: External operation mode, External JOG operation mode
H7B
H0002: PU operation mode, External/PU combined operation mode 1 and
2, PUJOG operation mode
H0000: Network operation mode
HFB H0001: External operation mode
H0002: PU operation mode (Pr. 79 = "6")
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 HFF, the
H6F 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 129)
H70 H0000 to HFFFF: Output current (hexadecimal) in 0.01A increments
H71 H0000 to HFFFF: Output voltage (hexadecimal) in 0.1V increments
H0000 to HFFFF: Monitor data selected in instruction code HF3
H72 When "0.01 to 9998" is set in Pr. 37 and "01" in instruction code HFF, the
data format is E2.
H73
H01 to H40: Monitor selection data
Refer to the special monitor No. table (page 196)
HF3
H0000 to HFFFF: Two latest fault records
H74 to H77
Refer to the alarm data table (page 197)
HF9
Control input commands such as forward rotation signal (STF) and reverse
rotation signal (STR). (For details, refer to page 197)
HFA
H79
Monitor the states of the output signals such as forward rotation, reverse
rotation and inverter running (RUN). (For details, refer to page 197)
H7A
Read set frequency/speed from RAM or EEPROM.
H6D
H0000 to HFFFF: Set 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 HFF, the
H6E
increments change to 0.001 and the data format is E2.
Write set frequency/speed to RAM or EEPROM.
H0000 to H9C40 (0 to 400.00Hz): Frequency increments 0.01Hz
HED
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.
HEE
To change the set frequency consecutively, write data to the inverter
RAM. (instruction code: HED)
