Frequency Converters Keep
Energy Costs Down
The EFC 3610 and EFC 5610 frequency
converters from Rexroth address energy-
consumption issues facing operators
of high-capacity pumps, compressors and
fans. Scalable in performance and functionality
features, the units can be integrated
into a wide range of automation
environments with simple commissioning
and open interfaces. These intelligent frequency
converters control machine speed
as demanded, potentially significantly reducing
energy consumption. Featuring a
removable operator display panel, the devices
allow simple commissioning without
need of external programming devices or
a PC—the user can auto-tune and enter,
change or backup parameters. Digital inputs/
outputs make simple direct coupling
with a PLC possible. Assembly is significantly reduced by time-saving installation
technology using plug-in terminals and
an attachment option on standard DIN
rail. The EFC3610 series cover the power
range from 0.4 to 22 kW or 0.5 to 30
hp, while the EFC5610 provides an expanded
range up to 90 kW or 125 hp and
safe torque off (STO). In addition to the
freely definable V/f (V/Hz) operation, the
EFC 5610 also offers vector control for an
optimal torque curve.
