ABB Launches Next-Gen MicroDrive


CARY, NC — ABB has intro- duced its next-generation Micro - Drive, ACH180, that complies with UL standards, including UL61800-5-1 for drives and UL60335-2-40 for HVACR (heat- ing, ventilation, air conditioning and refrigeration) equipment. As the newest addition to


ABB’s HVACR drive portfolio, the ACH180 enables expert con- trol of high-efficiency motors, while utilizing a compact design for space savings, lower capital expenditure and easier commis- sioning. The ACH180 drive’s design


allows operators to run motors based on the HVACR process demands, rather than running them at full speed and reducing output using mechanical controls like throttles or dampers, which greatly reduce energy consump- tion and CO2 emissions.

Series of stored program motion control systems controllers. The Allegra series of controllers is available as a desktop or stan- dard rack mount system. These easy-to-use, plug-and-


play, cost effective motion controllers can be configured for 1, 2, 3, or 4 axes of motion. With the appropri- ate drivers selected, any combination of stepper motors, DC brush-type servo motors with quadrature incremental encoders, three- phase brushless DC servo motors with quadrature incremental encoders or Hall effect sensors, or voice coil motors with linear encoders


can be controlled. The commands are written,

loaded and saved into the con- troller’s memory using the sup- plied free IDE. The controller is capable of running the com-


mands without the need of a host. The Allegra series also works with host programs such as: C/C++, Python, Visual Basic, LabVIEW™, and MATLAB™. Also, the system can be


operated using an analog joystick or a trackball. Options include: home and limit switches, TTL/CMOS inputs and outputs, and quadrature encoder feed- back.

ACH180 MicroDrive. Packed with HVACR-specific


features, the ACH180 includes industry-standard Hand/Off/Auto controls, fireman’s override for smoke control, and four start interlocks for remote troubleshoot- ing, including high static, smoke, freezestat, and fire stat. It supports the control of


various motor types, including permanent magnet-assisted syn- chronous reluctance motors like IE5 EC Titanium™ by ABB, per- manent magnet motors, and con- ventional


Further, onboard communication protocols,


induction motors. including BACnet


MS/TP and Modbus RTU, offer compatibility with a wide range of building automation systems
