Power quality input
Using either the 36 pulse DFE or the
AFE option, the MV6 Series more than
meets the industry requirements for
harmonic limits.
• Clean power input
• IEEE 519-1992 standard compliant
• No external filters
• No harmonic disturbance to other
online equipment
Input power factor
• .96 power factor DFE or unity
(default) power factor AFE for
energy savings
• No need for power factor correction
equipment
• With AFE, VARs can be supplied to
utility lines as an option
Motor-friendly output —
drive of choice for new &
retrofit applications
• Five-level PWM output — simulates
a sinewave providing smooth output
waveform to the motor
• Low VFD-induced torque ripple
• No special motor insulation
• No motor de-rating
• Works with standard motors
• Good for new and retrofit
applications
Power dip ride-through
The MV6 Series drive provides six-cycle
power loss ride-through and keeps the
process running without tripping.
Under-voltage operation
The MV6 Series operates continuously
and provides available power to the
motor at a lower input supply voltage
(up to 70% of nominal voltage).
Flying start
into a spinning load
The MV6 Series offers the ability to
catch and take control of a spinning
load without any damaging torque
impacting the equipment if restarted
while the load is already spinning.
Critical speed avoidance
The MV6 Series drive can be
programmed for up to three critical
frequency bands and ride-through
these without any resonance issues.
Independent acceleration
and deceleration ramps
The MV6 Series can be programmed
into the drive controls as needed for
controlled starting and stopping of
the load.
Ease of set-up & diagnostics
• Standard control interface offers
digital inputs/outputs and analog
inputs/outputs as standard. Each
of these inputs/outputs can be
programmed to a variety of different
functions for flexibility.
• Touchscreen operator interface
allows for quick, user-friendly
programming. Screens for fault
parameters and meters are user
configurable.
• MV6 Series tool suite is designed to
offer a full range of programming
and monitoring tools. Operating
data can be captured with a
snapshot feature and drive signals
can be trended. In addition, tool
suite offers trace-back data for
detailed fault analysis.
