1/8 - 10 Horsepower General
Purpose Vector Drive
The V7 is a low cost, high
performance compact drive, operable in V/f or Open Loop Vector
mode. In addition to good speed regulation, open loop vector
control also provides higher torque at lower speeds. The V7 is
ideally suited for applications such as conveyors, grinders,
centrifuges, pumps, fans,blowers, machine tools, packaging, food
processing, and commercial laundry. For wet and dusty indoor
environments, the V74X drive with integral NEMA 4X/12 enclosure
is recommended. For DeviceNet network applications, the V7N with
embedded Device Net is recommended.
Earlier versions of this product were named GPD 315/V7, GPD 315
or VS Mini V7.

The V7 Drive is a high performance AC drive for
induction motors, providing low motor noise and high
starting torque. The V7 provides two control methods;
V/f and open loop vector control for precision speed
regulation applications. In addition to good speed
regulation, open loop vector control also provides
higher torque at lower speeds. The V7 is intended for
constant torque applications, with current overload
rating of 150% for 60 seconds.
The V7 is fully featured and compact. The digital
operator provides 4-digit LED status display with a
built-in analog speed potentiometer, as well as digital
programming of almost 200 parameters. The digital pulse
train input provides a precise frequency input, and is
the perfect solution for speed / follower applications.
The seven standard multi-function inputs can be
programmed to allow for 17 preset speeds. The V7 also
has an analog input, a multi-function output, two
multi-function open collector outputs, and an analog
output as standard.
The V7 is ideally suited for applications such as
conveyors, grinders, centrifuges, pumps, fans, blowers,
machine tools, packaging, food processing, and
commercial laundry.
One of the outstanding options for the V7 is DriveWizard.
This software enables upload, download, and monitoring
of parameters. Another software, CASE, can add
functionality to the drive by reconfiguring drive
defaults, establishing presets for OEM equipment, and by
eliminating peripheral controls and PLCs.
A RS-485 Modbus RTU communication port is standard,
allowing 32 nodes on a single network. Plug-in interface
option boards enable the drive to communicate with all
the major networks, such as DeviceNet, Profibus-DP, and
others. The option board installs directly on the drive
control board via simple snap-in connectors.
A version of this drive called V7N is available with
DeviceNet embedded in the drive control board, reducing
cost and installation time.
Another version of this drive called V74X is available
with integral NEMA 4X/12 enclosure for dusty and wet
environments.
The V7 is provided in a NEMA 1 enclosure from 1/8 to 10
HP at 230 VAC and 1/2 to 10 HP at 460 VAC. (This V7 was
previously named GPD 315/V7)
