On-machine motor controller saves space and installation time

06 March 2012

The modular and compact Allen-Bradley ArmorStart LT distributed motor controller puts motor control on or near the machine, without need for an enclosure. This pre-engineered system helps simplify wiring, speeds up commissioning time and reduces the need for extra cabinet space. Operators are able to access parameters, status and diagnostics, regardless of location.

Installation 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 units 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.
