The AS1 adjustable speed drive builds on Toshiba's history of supplying powerful, reliable, and versatile drives. The modular construction of the AS1 allows the unit to be installed into nearly any application quickly and easily. The drive can operate with little or no programming. At the same time, the AS1 maintains one of the most expansive parameter sets in the industry. Its sealed cabinet design, new PID algorithm and motor-over-flux-braking technology make this drive adept to handle the most difficult applications. The AS1's advanced features and new technologies make it the new contender in the PWM control drive market.

Driven By Powerful Simplicity

Advanced Design
The modular construction of the AS1 allows the unit to be installed into nearly any application quickly and easily. The laminated bus-plane technology used in the AS1 allows for a reduced component count, enhanced reliability, and easier service.

Simple Programming
The AS1 drive can be operated by the user with little or no programming. At the same time, the AS1 maintains one of the most expansive parameter sets in the industry, allowing you to tailor the drive to your specific application.

Tough Environmental Conditions
The AS1 can operate in temperatures up to 122°F without derating and can also be configured for use in temperatures of up to 140°F. Designed to be used in a sealed cabinet, the AS1 allows integrators to mount the heat-sink externally to the drive cabinet for simple and efficient cooling of the unit.

Improved Control
The AS1’s improved PID algorithm makes it easier than ever to dial in your process control application. New parameters such as a delay filter and a process control lower limit, and new functions such as the AS1’s new speed PID and easy positioning algorithms, give the drive expanded capabilities to take on difficult applications.

Powerful Performance
The AS1 offers both sensorless and feedback vector control providing heavy duty performance. Toshiba’s motor over flux braking technology allows the AS1 to provide as much as 30% of its rated power for use in stopping a heavy or high inertia load without the use of a dynamic braking resistor.

Key Features

AS1 comes in a wide power range from 1 HP to 700 HP in 230V, 460V, and 600V Multitude of options available on this heavy duty rated drive including flange kits,remote keypads, dynamic braking transistors, communication options, extended terminal boards and more making this perfect for either the standalone or OEM style market.

Our sensorless vector control algorithm can maintain up to 0.1% speed accuracy while our closed loop vector control algorithm can maintain up to 0.01% accuracy

Advanced Features for Maximum Drive Performance

Built-In LED Interface
The AS1 allows for quick, user-friendly programming and easy modification of the expanded parameter set. The optional LCD keypad is able to store parameter sets which permit the user to set up multiple drives using these saved parameters.

My Function
Toshiba’s proprietary programming feature, allows the user to utilize logic-type programming without the expense of a micro PLC. The user is able to read analog and digital inputs and outputs as well as monitor and compare data. When programmed in a user-defined logic sequence, the use of this data will allow for a higher level of process control not normally seen in an adjustable speed drive.

Eight Digital Inputs & Three Digital Outputs
Each of these inputs/outputs in the AS1 can be programmed to any 1 of more than 67 possible functions. When used in conjunction with My Function programming, the capabilities of these terminals are virtually limitless.

A Built-In Proportional/Integral/Derivative (PID) Control Algorithm
The AS1’s control algorithm provides regulation of critical processes. High and low speed limits, deviation limits, online switching, and a built-in sleep function are included to enhance the flexibility and reliability of PID process control.

Toshiba’s Proprietary Windows®-Based ASD Pro Software
This easy to use software provides a full range of programming and monitoring tools for the AS1. Trending and logging features allow the user to save and transfer parameters and export data and graphs to electronic files that easily convert into spreadsheets or graphs for field and validation reports.

Industrial Applications

The AS1 drive can be utilized in industries as diverse as; Manufacturing, Mining, Quarry, Service & Repair, Timber, Metal & Mineral, and Oil & Gas.
