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.
f 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.
AS1 ac motor controlles
*  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:
DeviceNet,Ethernet/IP,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
Harmonic Filters,Remote-Mountable Keypads
