THE ACS550 from ABB is an adjustable frequency ac drive that achieves the ultimate in flexible motor control performance, according to the manufacturer.

Offering three modes of motor control: V/Hz, sensorless vector and flux vector, the ACS550 performs accurate speed and torque control of any standard squirrel cage motor.

With drives ranging from 1.0 to 500hp (0.75 to 355kW), the ACS550 series features an 'intuitively obvious' multi-lingual, full graphic display panel that also provides assistants to aid users in start-up, maintenance, and diagnostics.

The control panel can be mounted on the cover of the drive, or remotely, and can upload, store, and download parameters.

The ACS550 comes equipped with an extensive library of pre-programmed application macros that, at the touch of a button, allow rapid configuration of inputs, outputs, and parameters for specific applications to maximise convenience and minimise start-up time.

The ACS550 can be used for the simplest to the most demanding applications. Two integral option slots can be configured with additional relay outputs, encoder feedback, as well as a host of different communication bus adapters.

An integral brake chopper is provided on all R1 and R2 frame size drives.

The ACS550 is available in both a normal duty rating, and a heavy duty rating. The normal duty rating has a 10% short term overload rating, and the heavy duty rating has a 50% short term overload rating for one minute out of ten.
