Multi-axis controllers and drives

January 9, 2007

The Festo SEC-AC-SMLC Multi-Axis Controller is a fully-integrated control solution providing hardware and software building blocks that are engineered to easily plug together and work as a system. This allows engineers to focus on solving their application instead of integrating control components. Festo offers four models of the SEC-SDD drives with continuous output currents ranging from 2.4 to 14 A RMS/phase operating at 115VAC or 230 VAC. These digital drives make automatic loop adjustments based on motor and load inertia settings made via the configuration tool – ServoWire® Pro, greatly simplifying servo system tuning. The programming platform – CoDeSys — for the SEC-AC-SMLC motion controller is based on the IEC61131-3 standard, which offers a suite of programming languages (Relay ladder logic, Function Block diagram, Structured Text, Instruction List, Sequential Function Chart, and Continuous Function Chart) which simplify machine development and support. PLCopen Motion function blocks are available which cover both motion and administrative functions. Enhanced function blocks conforming to the PLCopen motion block definitions together with an option to develop application specific function blocks makes the SEC-AC-SMLC Motion system a very powerful, cost-effective and efficient solution that will meet all motion control & I/O needs.
