AC890
The latest compact, modular systems drive from Parker Hannifin, the global leader in motion and control technologies, offers system designers a high performance drives solution with more flexibility than ever. Called the AC890, the unit is compatible with virtually any feedback technology, enabling it to be integrated seamlessly into automation networks across a diverse range of applications, increasing productivity and profitability as a result.
The AC890 has been designed to control the speed and position of open- and closed-loop AC motors or Servo motors. With a powerful 150MHz microprocessor, it is able to meet the requirements of all variable speed applications, from simple motor speed control to integration of sophisticated multi-drive automation or process systems. In addition, the latest drive is able to achieve high-bandwidth control loops, allowing it to be used in a wide range of demanding industrial applications, such as printing, cut-to-length, rotary shear, converting and slitting.
Continuing the theme of flexibility, the AC890 features three user keypad options, allowing end users to choose to read drive parameters on one of three screen sizes. Remote mounting of the drive, required on some drive frame sizes, is also available.
Of particular benefit to operators is the AC890’s compatibility with any AC motor and virtually any speed/position feedback option, which, in many cases, makes it possible to improve productivity and system functionality without the need to replace existing AC motors, saving both time and money. The latest drive features high performance ports linked directly to fast control loops, resulting in minimal delay between the fieldbus setpoints and control loops. This also enables existing analogue setpoint-based solutions to be replaced by digital fieldbus-based solutions with minimal bandwidth loss.
The compact AC890 is available as a stand alone version or as a common bus version, which can contribute to achieving a smaller system design footprint. Furthermore, the drive can be configured for five different operating modes: open-loop (volts/frequency)
A high performance version of the AC890 can also be specified, which has all the features of the standard model plus a library of pre-engineered application specific LINK VM function blocks, such as shaftless printing, cut-to-length, advanced winding, and advanced traversing. Both versions of the drive can be configured and programmed quickly and simply using Parker’s dedicated software package, Drive System Explorer.
