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. | Pressing the <b>Run</b> pushbutton causes the VFD digital input (FWD/DI1) to go HIGH (+24V).

By defaulting to 60 Hz, the motor can be operated normally without the automation system, using the butterfly valve on the output side of the pump to adjust flow. | ||
