PowerFlex 700AFE Active Front End
Regenerate Power Back to the Utility and Lower Harmonics
Premier IntegrationFor simplified drive start-up and reduced
development time, the PowerFlex 700AFE
can be configured with RSLogix 5000 software. This single
software approach
simplifies parameter and tag programming while still allowing
stand-alone
drive software tool use on the factory floor.
Internal communication options help the user to cost-effectively
assemble
highly integrated applications. Options include: DeviceNet,
ControlNet, UniversalRemote I/O, and other open communications
including Profibus and Interbus-S.
Target ApplicationsThe PowerFlex 700AFE is an excellent solution
for common bus or single drive
applications that require AC line regeneration and/or low
harmonics.
The PowerFlex 700AFE Active Front End
is a great fit for applications that require
regeneration of power back to the utility
and/or low harmonics to meet IEEE-519
and CE standards. The PowerFlex 700AFE
is a regenerative DC bus supply used to
supply DC power to a line-up of common
bus AC drives or a single common bus
drive. The AFE utilizes a pulse width
modulated (PWM) controlled IGBT
converter to allow bi-directional power
flow to the AC line.
AdvantagesRegenerative Braking for Energy Savings
and Elimination of Braking Resistors
The AFE eliminates the need for large
resistor banks. These resistors banks
can create a lot of heat and must
frequently be cleaned. Instead of
wasting energy with resistor braking
technology, regenerative braking
actually puts the energy back into
the system to be used by other
equipment.
Low AC Input Harmonics
The active front end provides low
harmonics to meet IEEE 519 and CE
at its input terminals.
Improved Power Factor
The AFE itself actively controls the power
factor regardless of motor speed and
load. In addition, the PowerFlex700AFE
can be used for power factor correction
on the power system.
Voltage Boost
The AFE allows "input voltage boost"
operation, providing full 480 VAC to
the motor, even when operating on
380 VAC power lines. This voltage
boost also helps protect critical
processes from the potentially
disruptive effects of input voltage
dips and sags.
