may degrade the performance of sensorless operation. Therefore, run static type auto tuning by
selecting 2 (All) only when the motor cannot be rotated (when gearing and belts cannot be
separated easily, or when the motor cannot be separated mechanically from the load).
•
In PM synchronous motor sensorless control mode, check the motor’s name plate and enter the
motor specifications, such as the base frequency, pole number, rated current and voltage, and
efficiency, before performing auto tuning as the detected parameter values may not be accurate if
the motor’s base specifications are not entered.
Sensorless Vector Control for Induction Motors
Sensorless vector control is an operation to carry out vector control without the rotation speed
feedback from the motor. An estimation of the motor rotation speed calculated by the inverter.
Compared to V/F control, sensorless vector control can generate greater torque at lower speeds
and with lower levels of current.
