Cutler-Hammer® NFX9000 adjustable
frequency AC Drives from Eaton’s electrical
business are designed to provide adjustable
speed control of 3-phase motors. These
microprocessor-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
transistor (IGBTs) which provides 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 240V, single- or
3-phase, 50/60 Hz are available in sizes
ranging from
115V, single-phase, 50/60 Hz are available
in the
drive includes a digital display as well as
operating and programming keys on a
removable keypad. The display provides
drive monitoring and diagnostic information.
The keys are utilized for digital adjustment
and programming of the drive plus operator
control. Separate terminal blocks for control
and power wiring are provided for customer
connections. The drives feature RS485 serial
communications.
