The Drive for a Greener World

  • Environment friendly and saves energy

A1000 has the quality to suit any application. It has in-built features and parameters for major applications. The operator has to select the application and it will immediately optimize the drive for top performance.

Instance of Application presets

  • Select "Conveyor", it will optimizes parameter settings and get ready to operate conveyor application.

Long Life Performance

  • A 1000 can perform efficiently and durably for 10 years

Motor Life

  • Comparing synchronous and induction motors, the bearing life of synchronous is twice that of induction, given to the points of relative low copper loss in the rotor and a cool shaft at the time of operation.

Performance Life Monitors

Performance life equipped with in serves the purpose of preventing the problems before they occur by notifying the user about part wear and maintenance periods.

A signal is sent by the drive to the control device indicating components that need to be replaced.
