<strong>VFD</strong>-F Series3.6 Motor Operation Precautions1. When using the AC drive to operate a standard 3-phase induction motor, notice that theenergy loss is greater than for an inverter duty motor.2. Avoid running a standard induction motor at low speed. Under these conditions, themotor temperature may rise above the motor rating due to limited airflow produced bythe motor’s fan.3. When the standard motor operates at low speed, the output load must be decreased.4. If 100% output torque is desired at low speed, it may be necessary to use a special“inverter-duty” rated motor.3-18DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
