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
to the standard communications
features, Toshiba offers a number
of popular industrial communication
protocol options including: Modbus RTU, Modbus Plus, Ethernet
TCP/IP, Ethernet IP, Profibus DP, DeviceNet and Johnson
Controls Metasys N2.

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.
