AS1 460V Low Voltage Heavy Duty

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 means a reduced
component count, better reliability, and
easier service.

Simple Programming
Toshiba’s unified programming philosophy means that you can 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 fine-tune the drive for your specific application.

Tough Environment
The AS1 drive is designed to operate in extreme environments. It can operate in temperatures
up to 122°F without derating and can also be configured for use in temperatures of up to 140°F.
The AS1 is also designed to be used in a sealed cabinet design. This allows integrators to mount the AS1 heat-sink external to the
drive cabinet for simple and efficient cooling of the unit.

Improved Control
The AS1's new 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.
Using its new Motor-Over-Flux Braking Technology,
the AS1 can 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 brake resistor.

Smart Operation
Toshiba’s “My Function” programming set allows the
AS1 to operate as a simple PLC. Basic logic function
programming can now be done directly on the ASD.

Fault-Tracing
Issues with your application will no longer be a mystery
with AS1's fault-tracing algorithm. By accessing the fault-
tracing parameters, you can isolate exactly where the
trouble is located.

Easy Communications
The AS1 is designed to accommodate multiple stackable option cards that mount underneath
the unit’s keypad quickly and easily. In addition, the drive can accept two inputs from external
communication units via the two onboard RS485 communication ports.

Broad Compliance
The AS1 is certified by a broad range of governing and regulatory bodies making it a truly global
product.
