This function is enabled only when the 1st/2nd Control Method (A044/A244) is set to 03 (Sensorless
vector control).
When sensorless vector control is enabled, the inverter may output a rotation signal opposite to the
RUN command direction at low speeds, depending on the current accuracy. To prevent the motor from
rotating in the reverse direction, set the Reverse Rotation Prevention Selection (b046) to 01 (Enabled).
Use this function to monitor the motor output torque estimated by the sensorless vector control func-
tion.
This function is enabled only when the 1st/2nd Control Method (A044/A244) is set to 03 (Sensorless
vector control).
To monitor the motor output torque via the Digital Operator, display the Output Torque Monitor (d012).
For details on Output Torque Monitor, refer to
7-1-11 Output Torque Monitor [d012]
on page 7-8.
For how to monitor the motor output torque via the control terminal block signal, refer to
7-3-6 Terminal
MP (Pulse/PWM Output)
on page 7-27 or
7-3-7 Terminal AM (Analog Output)
on page 7-29.
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:
