New On-Machine Motor Controller from Rockwell Automation

22 February 2012

Machine builders can now offer customers a compact distributed motor controller that easily installs on the machine without an enclosure, and quickly connects to the enterprise network, thanks to the new family of Allen-Bradley ArmorStart LT distributed motor controllers from Rockwell Automation

ArmorStart LT distributed motor controllers are ideal for coordinating conveyor motor systems used in material handling and packaging applications and other types of warehouse distribution systems. The new family of distributed motor controllers provides the advantages of On-Machine architecture – a pre-engineered system that helps simplify wiring, speeds up commissioning time and reduces the need for extra cabinet space.

ArmorStart LT with EtherNet/IP connectivity improves the exchange of critical information about machine performance and component health, while allowing operators to access parameters, status and diagnostics, regardless of location.

“Machine builders need to provide motor control solutions that accommodate customers’ budgets and existing network architecture,” said Paul Gieschen, market development director, Rockwell Automation. “The new ArmorStart LT distributed motor controllers provide enhanced motor control at a lower price point and smaller package than other On-Machine motor control products on the market.”

ArmorStart LT is ideal in size and weight for most general material handling applications, making it easier to integrate on or near the conveyor or machine.

Installation also is simplified by the distributed motor controllers’ dual-port EtherNet/IP switch technology, which supports device-level ring (DLR) network topology. DLR-based networks reduce configuration time and costs by minimising the number of managed switches and reducing cabling needs. Users can create a single DLR network that connects all components at the device level locally. Information can be seamlessly communicated in real time to various levels of an organisation, without requiring additional complexity. Getting real time information at the right time and at the right levels of the manufacturing environment can enhance the agility of a business.

The distributed motor controllers include an add-on profile for Rockwell Software RSLogix 5000, the software used to program Allen-Bradley CompactLogix and Allen-Bradley ControlLogix programmable controllers from Rockwell Automation. The add-on profile’s automatic, predefined tag names provide manufacturers with a common language that can help improve consistency, and programming speed and efficiency.

The ArmorStart LT distributed motor controllers support a transparent clock to synchronise motor devices on an EtherNet/IP architecture, accommodating for delays introduced by other devices on the network.

To help enhance safety, the devices contain a standard, local disconnect feature that allows operators to turn off the motor and perform lockout tagout procedures during maintenance. They also are group-motor listed so multiple units can be grouped under one branch circuit protection device.
