Industrially Hardened
The H7 Adjustable Speed Drive is ready for continuous, trouble-
free operation in the most demanding manufacturing environments.
It has an interrupting current rating of 200 KAIC. In addition, it is
designed for an operating environment of -10 to 40° C at elevations
of -1000 to 1000 meters.
Speed Regulation
The capabilities of adjustable speed drives keep getting better.
Toshibaʼs proprietary vector control algorithm offers speed regulation
of 0.1% sensorless and 0.01% with motor feedback. Furthermore,
costly gear transmissions can be eliminated by using H7 ASDs that
can be digitally locked together for precise control requirements.

Torque: When and How You Want It
2
Toshibaʼs patented TRUE TORQUE CONTROL algorithm provides improved torque control in both
sensorless and feedback vector control modes. The H7 is capable of producing 200% torque at speeds
as low as 0.4 Hz and torque ripple as low as 2%. Toshiba gives you total control over your processes.
You can even decide when and how you apply torque to your mechanical systems with an analog input
signal.
Dynamic Mode Switching
The H7ʼs dynamic mode switching allows you to change between speed and torque control or position
control modes on-the-fly for seamless operation. Toshiba can show you how to maximize the efficiency
and performance of your process control.
Superior Design
The H7 is designed to operate with or without the use of DC link reactors. The robust capacitor bank
ensures efficient operation. Oversized power semiconductors provide higher tolerances and longer life.
In addition, standard phase-to-phase metal oxide varistors result in extra front-end protection from utility
power surges.
