W7 ASD
Installation and Operation Manual

Introduction
Congratulations on the purchase of the new W7 Adjustable Speed Drive!
The W7 Adjustable Speed Drive (ASD) is an 18-pulse PWM drive designed for use with 3-phase
AC induction motors. The 18-pulse design includes an 18-pulse input diode bridge rectifier
combined with an integral phase shifting transformer.
The drive has been designed with an 18-pulse front end to assist in the compliance of the
harmonic distortion limits of standard IEEE 519 1992 at the point of common coupling.
The W7 ASD is ideally suited to drive variable torque loads. Toshiba's technology, quality, and
reliability enables the motor to develop high torque and provide compensation for motor slip,
which results in smooth, quick starts and highly efficient operation. The W7 ASD uses digitally-
controlled pulse width modulation. The programmable functions may be accessed via the easy-
to-use menu. These features, combined with Toshiba's high-performance software, delivers
unparalleled motor control and reliability.
The W7 ASD is a very powerful tool, yet surprisingly simple to operate. The W7 ASD has an
easy-to-read LCD screen that provides easy access to the many monitoring and programming
features of the W7 ASD. The motor control software is menu-driven, which allows for easy
access to the motor control parameters and quick changes when required.
To maximize the abilities of your new W7 ASD, a working familiarity with this manual will be
required. This manual has been prepared for the 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.
