Product Description
Eaton’s Cutler-Hammer
®
MVX9000 is
offered in
a variety of enclosure options
to provide protection for operator and
equipment. Enclosure ratings include
Type 1,
12, 3R and 4X. (Enclosure
ratings are defined in PG03300001E.)
Model MVX9000 sensorless vector
adjustable frequency AC drives are
designed to provide adjustable speed
control of three-phase motors. These
microprocessor-based, sensorless vec-
tor drives have standard features that
can be programmed to tailor
the drive’s performance to suit a wide
variety of application requirements.
The MVX9000 sensorless vector product
line utilizes a 32-bit microprocessor
and insulated gate bipolar transistors
(IGBTs) which provide quiet motor
operation, high motor efficiency and
smooth low speed performance. The
size and simplicity of the MVX9000
make it ideal for hassle free installa-
tions where size is a primary concern.
Models rated at 575 and 480 volts,
3-phase, 50/60 Hz are available in sizes
ranging from 1 to 10 hp. Models rated
at 240 volts, single- or 3-phase, 50/60 Hz
are available in sizes ranging from
1/2 to7-1/2 hp.
The standard drive includes a digital
display, operating and programming
keys on a removable keypad. The dis-
play provides drive monitoring as well
as adjustment and diagnostic informa-
tion. The keys are utilized for digital
adjustment and programming of the
drive as well as for operator control.
Separate terminal blocks for control
and power wiring are provided for
customer connections. Other features
provided as standard include built-in
DC braking, RS-485 serial communica-
tions and PID control.
The enclosed microdrives can be
configured with standard modification
codes including options for various
cover controls, two- and three-
contactor bypass, communications
and traditional disconnect switch
offerings.
Type 1 Enclosure
The Type 1 version of the MVX9000
sensorless vector product line utilizes
a door-mountable (option) keypad.
The keypad, with digital display,
can be used for operating and pro-
gramming the MVX9000 drive. Type 1
enclosed MVX9000s offer a standard
gasketed cover in a ventilated
enclosure.
