Toshiba Industrial Systems
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.
AS1 Low Voltage Heavy Duty
Designed with the end-user in mind, the AS1 drive combines a rugged, proven power platform with the latest technologies to provide users with a smarter, stronger, more reliable drive with flexible application control. Advanced Design separates the AS1 from the competition. 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 allows the user to operate the AS1 drive 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 are no problem for the AS1 drive. Designed to operate in extreme environments, 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 is possible with the AS1's improved PID algorithm, making 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 is key to the AS1's success. 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.
Built-In LED Interface 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 are an integral part of the AS1's versatility. Each of these inputs/outputs 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 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 is available at no additional cost. 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.
The AS1 drive offers two RS485 ports with one full-duplex and one half-duplex, as well as a wide array of easily installed option boards. These boards allow the user to communicate with a wide variety of systems. Options include:
- Modbus Plus
- Profibus DP
- Profinet IO
- Modbus TCP/IP
The AS1 can be supplied with additional options to expand control, allow greater flexibility, and provide better protection for a user's application. These options include:
- AC Line & Load Reactors
- DV/DT Long-Lead Filters
- Extended Terminal Cards
- Encoder Feedback Cards
