Drive Systems & Motion Control ---

A main focus of Systems Interface relates to Drive Systems, which range in size from small to large…in excess of 1000 hp.

Our experience ranges from heavy movable structures, high inertia overhauling loads to CIP integrated multi-axis servo drive systems. Major markets include Aerospace, Marine, Movable Bridges, Material Handling, Manufacturing, Food, WTP and WWTP.

Systems Interface designs and delivers Drive Systems in a diverse field of applications including both AC and DC drive systems. Leading that field are moveable bridges….including bascule, swing, lift and draw span designs. A typical solution set consists of Rockwell Automation ControLogix® PLCs, Ethernet-based Remote I/O, Fiber Optic Networking, PanelViewPlus® Operator Interface Touchscreens, and FactoryTalk® Industrial Automation software.

Other drive system applications include heavy moveable structures, such as US Government radar antennas, telescope and antenna positioning systems, and rocket launch systems.

At Systems Interface, we pride ourselves in reacting quickly to opportunities, understanding risks and implementing designs that mitigate those factors, working beyond normal hours to manufacture and deliver systems in tight time schedules, and being creative in developing solutions with our suppliers.

Systems Interface retains unique engineering capabilities for application to:

  • Control Moving Drawbridges
  • Operate Highly Specialized Cranes
  • Control High-Mass Over-Hauling Loads

An example of a typical crane upgrades and retrofits done by the Systems Interface engineering team was the Henry M. Jackson (Sultan River) Hydroelectric Project where it was necessary to replace the existing DC motor drive control system with new DC drives as well as upgrade the crane controls with a new PLC based master control system.

Systems Interface provided new pre-assembled, tested, and UL listed Rockwell Automation Powerflex® DC drive backpanels for the 40 hp Main Hoist Motor and the 40 HP Auxiliary Hoist Motor. New DC drives were also provided for the 5 hp Trolley Motor and for two 10 hp Gantry Motors.

A new Rockwell Automation ControlLogix® PLC based master control system with I/O was provided which included an Operator Interface Touchscreen mounted inside the control cab along with a remote radio control system with variable speed control.

As with every Systems Interface Control System, the project was provided with all miscellaneous control hardware as required along with a complete As-Built Documentation with Bill of Materials, Electrical Schematics, Panel Layouts, Data sheets, PLC programs, etc, as well as a Description of System Operation and a recommended spare parts list.

Systems Interface provided a DC-Drive qualified Field Engineers to assist the owner with removing the existing back-panels and controls, installation of the new back-panels, testing, commissioning and training.

Systems Interface has been recognized by government municipalities (King county, Seattle, Washington, USA) as a uniquely qualified source for these specific control system engineering capabilities. We have the expertise as well as the experience to properly manage and control the inertia and dynamics of very high mass loads.

Winder Application

The following video is of a typical Winder. The System features an Advantech Touch Screen PC running Motion Commander® Software and Delta Tau Motion Control Boards. The Delta Tau Motion Control Board sends speed commands to Siemens 611U Servo Drives to control the Mandrel speed and Carriage position. Winding patterns are calculated in the Motion Commander Software. The video shows a dry run of a helical pipe wind for a large diameter fiberglass tank.
