Toshiba H7 Series POWERFUL...

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 K AIC. In addition, it is

designed for an operating environment of -10 to 40° C at elevations

of -1000 to 1000 meters.

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.

Toshibaʼs patented TRUE TORQUE CONTROL2 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.

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.

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.
