Easy Setup

Immediately setup with Application Presets

A1000 automatically sets parameters needed for all major applications. Simply selecting the appropriate application instantly optimizes the drive for top performance, saving enormous time, setting up for a trial run

Example using application presets

Selecting "Conveyor" optimizes five parameter settings so that drive is ready to start running your conveyor application immediately.

Long Life Performance

A 1000 with 10 years of durable performance

Motor Life

With relatively low copper loss in the rotor and a cool shaft during operation, synchronous motors have a bearing life twice that of induction motors.

Performance Life Monitors

Equipped with performance life monitors that notify the user of part wear and maintenance periods to prevent problems before they occur.

Drive outputs a signal to the control device indicating components that may need replacement.
