Why a variable frequency drive?
Key benefits
• User choice of input rectifier:
— Diode front-end (DFE) input is
easy to install with integrated
transformer and flexibility of
primary voltage
— Active front-end (AFE) is
transformerless with a small/
lightweight footprint and
four-quadrant regenerative
breaking capability
• Arc flash protected
• Modular construction
— Quick and easy power module
replacement
— Three wire in and out cable
connections — plug & play
• Conservatively rated standard
IGBT’s provide high availability
and low maintenance costs
• Visor Connect supports warranty
with remote real-time support
and advice
Power quality benefits
• Low input harmonics for better
power grid performance
• High power factor to increase
energy savings
• Motor-friendly output — suitable
for new and retrofit applications
Process control benefits
• Power dip ride-through to eliminate
nuisance trips
• Under-voltage operation to sustain
the process
• Flying start into spinning load — for
quick ramp-up of process
• Critical speed avoidance to ride-
through the resonance frequencies
• Independent acceleration and
deceleration ramps
• Ease of set-up & diagnostics

Simple & efficient control
of your process
Variable frequency drives (VFDs)
regulate motor speed to control the
flow and pressure of blowers or pumps
without dampers or throttling valves.
This results in energy savings and
minimizes output waste. VFDs also
provide a soft start to the motors,
reducing the stress on driven load and
resulting in lower maintenance costs.
Appropriate power usage
in response to load
A VFD manages power based
on actual demand and uses only
the energy required by the driven
equipment to provide valuable
energy savings.
Avoid peak demand charges
When starting large motors with VFDs,
current inrush peaks are eliminated.
The VFD gradually ramps the motor
up to speed by varying output voltage,
current and frequency for a soft start.
