Power and Control

Alexander & Associates was responsible for the Power and Control design of a global rollout. Several machines were designed utilizing our mechanical, electrical, and fluid power design capabilities resulting in CE compliant design packages for the equipment. In addition, we provided design packages to integrate these machines with vendor purchased equipment creating a totally integrated control system for the production line.

The equipment consisted of variable speed drives and servos controlled by Rockwell Automation controllers. Machine designs utilized servo drives for maximum flexibility and ease in changeovers. Human-Machine Interface (HMI) terminals running CTC Interact® software provided optimum accessibility for operators. The center of the control system was a Rockwell PLC5 based system programmed with RSLogix® software. The control architecture allowed for complete modularity of the equipment while also providing the communicators necessary for proper synchronization and interfacing between machines.

HIGHLIGHTS:

  • Complete hardware design using Promis·e® software
  • Extensive machine flexibility utillizing programmable controllers and servo drives
  • Equipment Installation/Startup support at North American and European plant sites
  • Power system design accommodating 480 volt, 60Hz and 400 volt, 50Hz systems
  • Global considerations: IEC format, Multilanguage documentation
  • 24VDC control for safety and global flexibility
