For the data codes or details of fault records, refer to the Instruction Manual
(Detailed) of the FR-A800/FR-F800 inverter.
Read the set frequency/speed from the RAM or EEPROM.
H0000 to HE678: Set frequency in 0.01 Hz increments

inverter.))
• For the FR-A800-E, when Pr.544="0, 1, or 12" and Pr.804="3 or 5" during torque
H6E
control under Real sensorless vector control or vector control, torque command
values are read. The setting range depends on Pr.804.
Write the set frequency/speed into the RAM or EEPROM.
H0000 to HE678 (0 to 590.00 Hz): frequency in 0.01 Hz increments
(The display can be changed to the rotations per minute using Pr.37, Pr.144 and

inverter.))
• To change the set frequency consecutively, write data to the inverter RAM.
(Instruction code: HED)
• For the FR-A800-E, when Pr.544="0, 1, or 12" and Pr.804="3 or 5" under torque
HEE
control under Real sensorless vector control or vector control, torque commands
are given.
The setting range depends on Pr.804.
• Refer to the instruction code in the Instruction Manual (Detailed) of the FR-A800/
FR-F800 inverter to read and write as required.
H00 to H63
Write to Pr.77 and Pr.79 is disabled.
When setting Pr.100 and later, set link parameter extended setting.
• Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
H80 to HE3
• When changing the parameter values frequently, set "1" in Pr.342 to write them to
the RAM. (Refer to
HF4 H9696: Clears the faults history as a batch.
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 the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter for
parameter clear, all clear, and communication parameters.
Clear type
Parameter clear
HFC
All parameter clear
When clear is executed for H9696 or H9966, communication-related parameter
settings also return to the initial values. When resuming operation, set the
parameters again. Executing clear will clear the instruction code HEC, HF3, and
HFF settings.
HFD H9696: Resets the inverter.
H00 to H0D: Parameter description is changed according to the instruction code
H7F
(extended) setting. Refer to the Instruction Manual (Detailed) of the FR-A800/FR-

F800 inverter for instruction code (extended) settings.
Read or write of bias and gain parameters (instruction codes H5E to H61 and HDE
H6C
to HE1 with the link parameter extended setting = "1", H11 to H23 and H91 to HA3
with the link parameter extended setting = "9").
