Product Description
Cutler-Hammer

NFX9000 adjustable
frequency AC Drives from Eaton’s
electrical business are designed to
provide adjustable speed control of
three-phase motors. These micro-
processor-based drives have standard
features that can be programmed
to tailor the drive’s performance to
suit a wide variety of application
requirements.
The NFX9000 volts-per-hertz 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 NFX9000
make it ideal for hassle free installation
where size is a primary concern.
Models rated at 240 volts, single- or
three-phase, 50/60 Hz are available in
sizes ranging from 1/4 to 2 hp. Models
rated at 115 volts, single-phase, 50/60 Hz
are available in the 1/4 to 1/2 hp size
range.
The standard drive includes a digital
display, operating and programming
keys on the 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. The drives
feature RS-485 serial communications.
