Model MVX9000
Product Description
Cutler-Hammer
vector adjustable frequency AC Drives
from Eaton’s electrical business are
designed to provide adjustable speed
control of three-phase motors. These
microprocessor-based, sensorless
vector 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 installation
where size is a primary concern.
Models rated at 480 volts, three-phase,
50/60 Hz are available in sizes ranging
from 1 to 10 hp. Models rated at 240
volts, single- or three-phase, 50/60 Hz
are available in sizes ranging from 1/2
to 7-1/2 hp. Models rated at 115 volts,
single-phase, 50/60 Hz are available in
the 1/4 to 1 hp size range.

The standard drive includes a digital
display, operating and programming
keys on a removable keypad.
The display provides drive monitoring
as well as adjustment and diagnostic
information. 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 communications and PID control.
