Where are Variable Frequency Drives used?
> Variable Frequency Drives (VFD’s) are mainly used to
control 3-phase asynchronous AC electric motors.
> They are used in many types of applications:
> Pumping
> Ventilation
> Conveyors
> Hoists and Cranes
> Packaging machines
> Automatic doors
> Industrial machines
Confidential Property of Schneider Electric
What does a Variable Frequency Drive do?
> A VFD controls the operation of a motor allowing:
> Control of acceleration of the motor
> Control (and change) of speed of the motor
> Control of deceleration of the motor

How does a Variable Frequency Drive do this?
> A VFD controls the
operation of a motor
by regulating:
> Voltage supply to
the motor
> Current supply to
the motor
> Frequency of the
AC current to the
motor

Pump curves embedded:
• Easy to set
• Embed 5 points from pump curve and assess efficiency
Advantages:
• Monitor [Head vs Flow], [Power vs Flow], [Efficiency vs
Flow] and [Power vs speed]
• Sensor-less Flow Estimation with Head Vs Flow curve or
Power Vs Flow curve
• Monitor outlet pressure, inlet pressure, water level,
• Raise alarms according to actual status

Process Asset Protection Functions
Pump Protection Functions
• Cavitation Protection by inlet pressure monitoring,
• Dry running protection,
• Hydraulic network protection by outlet pressure monitoring,
• Pipe burst prevention by high flow monitoring,
• Pump overheating prevention by low flow monitoring,
• Pump cylic start function to protect the pump against too many restarts,
