Additional EMC filtering options,
configurable analogue inputs and
enhanced fieldbus connectivity are
among the new features that have
been added to the latest M-MAX
variable speed drives from Eaton’s
Electrical Sector, which are available
with ratings up to 7.5kW.

Featuring compact book-style
construction, competitively-priced
M-MAX drives can be configured by
the user for either V/f or sensorless
vector control. This makes them
suitable for energy-saving fan and
pump applications, and for general
industrial applications where
accurate speed control is needed.

A large built-in display and
operating unit makes it easy to
configure the drives and monitor
performance, while an electronic
setpoint potentiometer facilitates
accurate speed setting. Versatility is
further enhanced by the 1.5x shortterm
overload capacity, flying-start
feature, PID functionality and, on
larger units, an integrated brake
chopper.
