Overview
The Allen-Bradley 1394-AM03 is a servo (axis) amplifier module that converts DC bus power to variable AC voltage for controlling one AC servo motor axis within a 1394 multi-axis motion control system. Part of the 1394 GMC (Graphic Motion Controller) and GMC Turbo platform, this Series B module delivers reliable motion control in industrial automation, packaging, material handling, and press applications. The module integrates with the 1394 system via a slide-and-lock connector mechanism that eliminates complex wiring harnesses.
Key Features
