ABB's ACS 600 frequency converters achieve the ultimate in AC motor control performance

The ACS 600 performs precise precise speed and torque control of standard squirrel cage motors-without the added cost and inconvenience of pulse encoder feedback.Infact, DTC has brought about fundamental changes to the way in which a motor can be controlled, so that now, in any application, the overall effectiveness of a drive is limited by the performance of the motor-not the frequency converter.

The ACS 600 product family includes models to suit virtually any application or operating environment, with a complete selection of voltage, power and enclosure ratings, combined with highly flexible control and communications capabilities.

• Motor starting torque up to 200 % of nominal torque
• Accurate open loop torque control
• Torque step rise time typically less than 5ms
• Speed control inaccuracy typically 0.1 % to 0.5 % of nominal speed.

• 3 programmable differential analogue inputs(1 voltage signal, 2 current signals)
• 6 programmable digital inputs
• 2 programmable analogue outputs(current signals)
• 3 programmable digital outputs (from C relays)

Optional analogue and digital extension modules can be added as well as a wide range of fieldbus adapters.

The ACS 600 features a selection of built-in pre-programmed application macros for configuration of inputs, outputs, signal processing and other parameters.

These include:

• Factory setting for basic industrial applications
• Hand/Auto control for local and remote operation
• PID control for closed loop processes
• Torque control for processes where torque control is required.
• Sequential control for repetitive cycles.
• User macro 1 & 2 for user's own parameter settings.

The ACS 600 series provides a selection fo ready made application macros and a wide range of fully programmable inputs and outputs.Should your application require distributed or high resolution control signals, analogue, and digital extension modules can be added.Optional modules mount on standard DIN rails and connect via a high speed fibre optic link.

Fieldbus adapter modules are available for all the common fieldbus standards including Profibus, Modbus, Modbus Plus,ABB MasterFieldbus, Interbus-S,DeviceNet and others.

ACS 600 frequency converters meet the needs of any application-from the simplest to the most critical and highly demanding.
