For the data codes or details of fault records, refer to the Instruction Manual (Detailed)
of the inverter.
Read the set frequency/speed from the RAM or EEPROM.
H6D H0000 to HFFFF: Set frequency in 0.01 Hz increments
(The display can be changed to the rotations per minute using Pr.37, Pr.144
and Pr.811. (Refer to the Instruction Manual (Detailed) of the inverter.))
• When performing torque control under Real sensorless vector control or vector
H6E
control with Pr.544 = "0, 1, 12" and Pr.804 = "3 or 5", read torque command value.
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
HED
(The display can be changed to the rotations per minute using Pr.37, Pr.144
and Pr.811. (Refer to the Instruction Manual (Detailed) of the inverter.))
• To change the set frequency consecutively, write data to the inverter RAM.

• When performing torque control under Real sensorless vector control or vector
control (torque control) with Pr.544 = "0, 1, 12" and Pr.804 = "3 or 5", torque
HEE
command is set.
The setting range depends on Pr.804.
