Advantages of a medium voltage variable
frequency system

MV7000 — Enhanced technology

Reliability & availability

The higher reliability and lower
maintenance needs of a variable
speed drive system compared to
gearboxes and hydraulic couplings
result in lower lifecycle cost.

Saving energy, caring for
the environment

In today’s world more than ever,
energy saved is energy produced.
For a variety of loads, from water
pumps to gas compressors, variable
speed control offers the best way
to capture energy savings.

Precise power delivery

In many applications, the superiority
of electrical control simply cannot
be matched by mechanical systems.
Precise control of power means better
outcomes, from the flatness of a steel
sheet to the accuracy of offshore
Oil & Gas exploration.

Key benefits

• Peak power density

• High reliability and availability

• Power scalability with customizable
options featuring:

– Low harmonics without

additional equipment

– Four quadrant operation for

regenerative applications

High reliability and availability

Power scalability with customizable options

MV7000 comes in a standard Diode-Front-End (DFE) rectifier configuration.

The MV7000 is a great example
of a design philosophy based on
minimizing component count while
retaining peak performance.
Press-pack IGBT (PPI) power
devices enable:

• The capability to limit overcurrent
with safe turn-off under all operating
and failure conditions

• Case rupture-free due to pressed
contacts and no-wire bonding

Process control benefits

MV7000 — À la carte option packaging

Incoming power dip
ride-through

The MV7000 provides incoming power
loss ride-through and keeps the
process running without tripping.

Under-voltage operation

The MV7000 operates continuously
and provides power to the motor at
a lower input supply voltage (down
to 70% of nominal voltage).

Flying start into a
spinning load

The MV7000 offers the ability to
catch and take control of a spinning
load without any damaging torque,
voltage or current impacting the
equipment if started while the load
is already spinning.

Critical speed avoidance

The MV7000 can be programmed for
up to three critical frequency bands
and ride-through these without any
resonance issues.

Independent acceleration
and deceleration ramps

The MV7000 can be be programmed
into the drive controls as needed for
controlled starting and stopping of
the load.

Feature suite for
every application

Standard product customizable with
pre-engineered options including, but
not limited to:

• Redundant pump for cooling
