Pressing the <b>Run</b> pushbutton causes the VFD digital input (FWD/DI1) to go HIGH (+24V).  Assuming the safety module is reset, the VFD will operate (ramp up?) to full speed (60 Hz).  The speed may be reduced via closed-loop control from the automation system (based upon flow meter feedback).  By defaulting to 60 Hz, the motor can be operated normally.
