G7 Drive: 208 to 240
VAC 1/2 to 150 HP, 480 VAC 3/4 to 500 HP
This amazing AC drive is the ultimate performance solution
with increased speed and torque response to provide servo-like
performance from an induction motor. In addition, the G7 drive
includes the world's first Inverter architecture that
eliminates or minimizes the installation problems associated
with IGBT switching on 480 volt systems and protects the
entire motor-drive system.
G7 drive performance makes it the ideal drive for high
performance speed, torque, or position control applications.
Several control modes are provided. In open loop vector mode,
the latest flux observer algorithms extend speed range and
provide maximum starting torque. In closed loop vector mode,
0.01% speed regulation and 1000:1 control range can be
achieved. Zero-servo capability provides position control at
zero speed.
The G7 drive has the world's first 480V 3-Level Inverter
architecture for total system protection. This patented
3-Level architecture can eliminate peripheral components
typically required to solve installation problems sometimes
encountered on 480 volt systems. The G7 allows motor operation
at very long cable lengths, meeting NEMA MG1 Part 31, with
peak voltage being 30% less than conventional. With motor
bearing current being typically 50% less than standard
inverters, the G7 provides four times the motor bearing life.
Audible motor noise on the 480 volt G7 drive is 5-10 dB (20%)
less than the prior generation drive, even when operating at
half the carrier frequency. Common mode current is half that
of conventional drives. The G7 power section includes built-in
bus choke (most ratings), 12-pulse input capability (most
ratings), common DC bus capability, and regeneration options.
The G7 drive has three autotuning methods to optimize motor
control, including the new static autotuning which does not
require load decoupling nor motor rotation. The LCD operator
displays 5 lines x 16 characters, in any of 7 languages. The
keypad is intuitive and includes memory for parameter
settings, making it easy to transfer settings from one drive
to another. To further aid in parameter management,
DriveWizard™ software for the PC is available at no charge,
for upload, download, archiving, trending, and graphing.
The G7 drive has a large programming feature set to handle
sophisticated industrial applications. If the standard feature
set does not meet your specific requirement, the G7 can be
programmed using DriveWorksEZ™. This is a PC-based,
object-oriented, graphical icon programming tool that is
friendly to the user. The drive firmware can also be modified
by custom or prewritten application-specific modules such as
Motion Control or Electronic Lineshaft.
The G7 drive supports the industry's preference for open
network architecture and connectivity with network choices
such as DeviceNet, Profibus-DP, Ethernet, and others.
The G7 is not intended for the simple, routine AC drive
application, it is for the challenges. The G7 drive offers the
ultimate performance, the best system protection, and the most
flexible configurations of any drive available.
