Introduction
Congratulations on the purchase of the
GX9 Adjustable Speed Drive
!
The
GX9 Adjustable Speed Drive
(ASD) is a solid-state AC drive that features Toshiba International
Corporation’s (TIC)
Virtual Linear Pump
Technology
(VLP Technology) and
Vector Control
algorithms. The
Virtual Linear Pump
Technology
and
Vector Control
algorithms provide easy setup,
enhanced reliability, and precise control under the most demanding conditions — all while enabling the
motors of the system to develop high starting torque and providing compensation for motor slip. The
result is setup ease, smooth starts, and highly efficient operation.
The
Virtual Linear Pump Technology
algorithm was designed to remove the guess work that is
normally associated with the setup of pumping systems. It allows for direct, linear, and precise pump
curve responses at any flow or pressure setting. This is accomplished without the normal concerns of
the adverse effects of conventional pumping system control response curves.
Using
Virtual Linear Pump Technology
, the system seamlessly and easily adapts to peak load
demands while maintaining the same degree of high performance output and reliability across the entire
load range - all without any user intervention!
The
GX9 ASD
is a very powerful tool, yet surprisingly simple to operate. The user-friendly
Electronic
Operator Interface
(EOI) of the GX9 ASD has an easy-to-read LCD screen and a high-intensity LED
display. The EOI provides easy access to the many monitoring and programming features of the GX9
ASD.
The
GX9 ASD
uses digitally-controlled pulse width modulation. The programmable functions may be
accessed via the easy-to-use menu, via the
Direct Access Numbers
(see
), or using
communications via a host PC. The ease of system access to the monitoring and control features
combined with Toshiba’s high-performance software, delivers unparalleled motor control precision and
reliability.
This manual has been prepared for the
GX9 ASD
installer, user, and maintenance personnel. This
manual may also be used as a reference guide or for training. With this in mind, use this manual to
develop a system familiarity before attempting to install or operate the device.
