Technical Explanation for Inverters - Omron
www.ia.omron.comSensorless Vector Control Sensorless means that there is no feedback from an encoder. Although there is no feedback signal from a sensor, the current and voltage output from the inverter to the motor are used to correct the output waveform. This enables finer speed control. + Fixed frequency (50/60 Hz) Capacitor
