Installation & Operation Manual

Introduction
Congratulations on the purchase of the new WX9 Adjustable Speed Drive!
The WX9 Adjustable Speed Drive (ASD) is an 18-pulse PWM drive designed for use with three-phase
AC induction motors. The drive has been designed with an 18-pulse front end to assist in compliance with
the harmonic distortion limits of standard IEEE 519 1992 at the point of common coupling.
The WX9 ASD is equipped with Vector Control to provide 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 smooth starts and highly efficient
operation.
The WX9 ASD is a very powerful tool yet surprisingly simple to operate. The user-friendly Electronic
Operator Interface (EOI) 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 WX9 ASD.
The WX9 ASD uses digitally-controlled pulse width modulation. The programmable functions may be
accessed via the Program Menu, via Direct Access Numbers, or by using communications via a host
PC. These features, combined with Toshiba's high-performance software, deliver unparalleled motor
control and reliability.
This manual has been prepared for the WX9 ASD installer, user, and maintenance personnel. This manual
may also be used as a reference guide or for training. To maximize the abilities of your new WX9 ASD,
use this manual to develop a system familiarity before attempting to install, operate, or perform
maintenance on the device.
