AS3 Low Voltage Drive


Toshiba’s AS3 adjustable speed drive is designed with an emphasis on built-in communications, allowing end-users to access real-time data and refined controls to maximize system performance.

Industry 4.0/IoT (Internet of Things) – Industry 4.0 is the evolution of manufacturing, empowering businesses to learn and adjust from data available through connected manufacturing.
Dual Port Ethernet IP – Enables simple connection of multiple AS3s together on one network while simplifying cable management.
Embedded Web Server – Allows for quick access to Ethernet IP setup, parameters and real-time monitoring for diagnostics. Accessible through standard web browsers on PC, tablets, and smart phones.
Built-in LCD Display & Advanced Keypad – Multi-language LCD display, remote mounting, available IP65 cover, transfer/save parameters, real-time clock for fault logging, and calendar functionality.
QR Codes – Displayed when troubleshooting faults or alarms, providing immediate access to a dedicated web link for maintenance and support.
STO Terminal – Detachable terminal strip meets IEC directives for safety with full implementation of Safe-Torque Off, which quickly shuts down the system in the event of an emergency stop.
Permanent Magnet Motor Control – For control of permanent magnet (PM) motors with higher torque and efficiency values.
Pump Control – Multi-PID control with sleep function and the ability to autonomously control booster pumps based on system demands or operating a secondary PID control loop.
ASD Pro Software – Toshiba’s programming software, which allows the user to utilize logic-type programming without the expense of a micro PLC.


In addition to the built-in dual port Ethernet, the AS3 can make use of a wide array of easily installed option boards. These boards allow the user to communicate with a wide variety of systems when installed cassette style. Options include:

• Ethernet TCP/IP (embedded)• EtherCAT• CAN open
• Modbus RTU (embedded)• PROFIBUS-DP
