Introduction
Congratulations on the purchase of the new H9 True Torque Control
2
Adjustable Speed Drive (ASD).
The H9 True Torque Control
2
Adjustable Speed Drive is a solid-state AC drive that features True
Torque Control
2
. Toshiba’s Vector Control Algorithm enables the motor to develop high starting torque
and provide compensation for motor slip, which results in smooth, quick starts and highly efficient
operation. The H9 ASD uses digitally-controlled pulse width modulation. The programmable functions
may be accessed via the easy-to-use menu or via the Direct Access Numbers (see
page 76
). This feature,
combined with Toshiba’s high-performance software, delivers unparalleled motor control and reliability.
The H9 ASD is a very powerful tool, yet surprisingly simple to operate. The user-friendly Electronic
Operator Interface (EOI) of the H9 ASD has an easy-to-read graphical LCD screen. There is also a read-
only LED display with enhanced visibility that can be read from a greater distance. The EOI provides
superior viewing features for the user and easy access to the many monitoring and programming features
of the H9 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 H9 ASD, a working familiarity with this manual will be required.
This manual has been prepared for the H9 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.
