features True Torque Control . TIC'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 H7 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 pg. 48). This
feature, combined with Toshiba's high-performance software, delivers unparalleled motor control and
reliability.
The H7 software functions is a very powerful tool, yet surprisingly simple to operate. The H7 has an easy-
to-read 240 x 64 pixel graphical LCD screen with a user-friendly Electronic Operator Interface (EOI).
The EOI provides easy access to the many monitoring and programming features of the H7.
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 H7, a working familiarity with this manual will be required. This
manual has been prepared for the H7 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
