Selected past applications:

FIBER

Courtaulds Fibers - Tencel

QDS personnel designed and commissioned a $2M fiber production process drive system, including Allen Bradley variable frequency drives, Anderson AC vector drives, motors and encoders, motor control centers, drive regulator panels, remote I/O panels including Allen Bradley PLC-5 integrated with (200) relay hardwired e-stop system and video control panel, PLC programming, drive regulator programming, video control panel programming, setup and configuration programming of (4) PCs including engineering workstation, fault monitoring and diagnostic system (includes DDE spreadsheet transfers), local maintenance workstation and remote dial-in node. Included full system simulation test prior to shipment. Provided field installation management, startup and acceptance testing over a 9 month period. This was the second system QDS personnel designed for this customer.

STEEL

ISPAT

Designed and commissioned 48 drive sheet steel cleaning line drive system using common bus Siemens AC Vector drive technology. Featured GE-9070 to Profibus direct communications, constant tension uncoiler and winder, line speed setting bridles, tension regulated bridles and speed follow of master via Profibus high speed network. Drives were built in a back to back configuration with a DC common bus on (5) 1600mm x 2600mm I-beam skids. Full system simulation test completed prior to shipment. Total value of project equipment, engineering and commissioning $1.2M.

FILM

Abbott Laboratories

Designed, built and commissioned (2) heavy gauge film lines using Siemens DC 4 quadrant drive technology. Re-engineered to convert from Emerson analog DC controls to make two dissimilar lines similar. Custom panel layout and wire numbering to reuse existing cabinetry and field wires. Featured digital peer to peer master follower, external speed ratioing, die shimming and multiple motor profiles. Full system simulation test completed prior to shipment. Total value of project equipment, engineering and commissioning $100K

FOOD

Flowers Baking Company

Designed, constructed, commissioned numerous systems at several bakeries since 1989 including (3) bread oven control systems (motor controls, PLC, burner management, operator interface), updated domaker / automated dough preparation system (PLC, dozen drives, video control panel), brew batching system (Lookout operator interface, and instrumentation) proof and bake and various conveyor systems. Total projects value $740K.

PAPER

Riverwood International

QDS personnel designed and commissioned an all digital AC vector drive system on a seven section Research and Development Pilot Coater Paper Machine. Design features included multi-master regulator, speed and tension control, load sharing, .01% speed regulation with draw control, video control panel operator control station and direct digital communication link to Allen Bradley PLC-5's and variable frequency drives.

Mobile Paperboard

QDS personnel completed retrofit of Siemens DC surface winder drives with an analog implementation to a fully digital system using Siemens technology boards. Replace operator control and provided installation, startup and cutover project management. Provided greater reliability, serviceability and consistent wind performance.
