Industrially Hardened
The H7 Adjustable Speed Drive is ready for continuous, troublefree 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
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.
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.

Built-In Communications
In todayʼs fast-paced manufacturing world, coordinated systems require communications from drive-to-drive or drive-to-control systems. Toshibaʼs H7 comes standard with RS232/485 and TTL communications ports. In addition

Process Control
The built-in Proportional/Integral/Derivative (PID) control loop provides regulation of many processes without the need for external devices. Deviation limits, online switching and delay filtering functions are included to enhance the flexibility and the reliability of PID process control. The torque control and drooping control functions of the H7 allow precise matching of motor torque for load sharing applications.
Adaptability
The H7ʼs programmable discrete inputs may be configured to any of 68 different functions and are independently selectable for normally open or normally closed operation.
The H7ʼs four multi-function analog inputs have independently adjustable bias and gain. From common potentiometers for speed control to analog summing for trim and process control, the configurability of the H7ʼs analog inputs are adaptable to your processes.
The removable control terminal strip is available in dry contact, TTL or 120 VAC configurations and may be optionally DIN Rail mounted. The operator interface can be easily mounted remotely and configured for NEMA4/NEMA12 environments.
