4. Parameter description
Parameter
• If you need Sensorless vector control, you should set P.300 to 3.
Note: 1. Motor capacity and inverter capacity must be with grade or sub-grade.
2. If P.187=1, the sensorless vector control function is invalid.
3. To do auto measurement function, such as permitting motor rotation, set P.301 to 1
(Dynamic measurement), then it should be made load off the motor completely. Such as loading conditions
don't allow the case which the motor rotation when Auto-tuning automatic measurement function, please
set P.301 to 2 (Static measurement).
4. Sensorless vector control: measurement by automatic (Auto-tuning) function to enhance the control
performance. Set the motor parameters or do auto measurement function before set P.300 to 3, in order to
increase the control accuracy
