HED
(The display can be changed to the rotations per minute using Pr.37, Pr.144 and
*6
Pr.811
. (Refer to the Instruction Manual (Detailed) of the inverter.))
• To change the set frequency consecutively, write data to the inverter RAM.
(Instruction code: HED)
• For the FR-A800 series, 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 inverter to read
and write as required. Write to Pr.77 and Pr.79 is disabled. When setting Pr.100 and
H00 to H63
later, set link parameter extended setting.
• Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
• When changing the parameter values frequently, set "1" in Pr.342 to write them to the
H80 to HE3
RAM. (Refer to the Instruction Manual (Detailed) of the inverter for details.)
HF4
H9696: Clears the fault history as a batch.
All parameters return to the initial values.
Whether communication parameters are also cleared or not depends on the data.
• Parameter clear
H9696: Communication parameters are cleared.
*7
H5A5A
: Communication parameters are not cleared.
• All parameter clear
H9966: Communication parameters are cleared.
HFC
*7
H55AA
: Communication parameters are not cleared.
Refer to the Instruction Manual (Detailed) of the inverter for parameter clear, all clear,
and communication parameters.
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.
