7-1-10 Torque Bias Monitor [d010]
Use this function to display the current torque bias value under sensorless vector control.
The torque bias monitor function estimates the torque value equivalent to the rated current of the
inverter as 100%.
To convert it to the rated motor torque ratio, use the following formula:
Rated motor torque ratio = Monitor value  Rated output current of inverter / Rated motor current
For details on the torque bias monitor function, refer to 6-4-2 Torque Bias Function Settings on page

7-1-11 Output Torque Monitor [d012]
Use this function to display the estimated output torque value of the inverter.
The value is displayed only when sensorless vector control is selected.
The output torque monitor function estimates the torque value equivalent to the rated current of the
inverter as 100%.
To convert it to the rated motor torque ratio, use the following formula:
Rated motor torque ratio = Monitor value  Rated output current of inverter / Rated motor current
