We are always looking for new challenges in automation
Over the years SA Power has developed many solutions for unique applications. As a team we enjoy such challenges and share some of them with you here.
Mine Winder Liquid Controller
Lenze servo and control systems developed to control winder liquid controllers and the operator lever and interface.
These systems have been used for a range of mine winders locally and overseas.
Crane Application 103 meters and load cells
Crane application controlling the sluice gates for Lesotho Highlands water project.
The depth of the sluice gates was managed with cable length control as well as load cell feedback to manage cable slack and other safety requirements.
Aluminium Line Cross cut
Aluminium cross-cut saws managing cut accuracies over 70m lengths. Squareness of the cut and accuracy are key components.
Operator interface to allow a wide range of functionality.
The nature of the plant required precise control and reliable technologies.
The main PLC system used was Emerson CPL410 with RSTi EP io, Cimplicity Scada with 150 tags and remote interface for connectivity and remote support.
The network used was Profinet to 24 off Lenze i550 series inverters. The Lenze i550 inverters provide an optimum solution for motor control for gas flow, pumps, conveyors, fans and rotational drums.
This system solution was significant due to extensive control and Scada knowledge by the implementation team.
Door control for Medical Use
Precise and smooth control of heavy doors in a medical environment. Lenze servo control with high reduction low backlash geared units offered this solution with easy set-up as well as low noise and smooth operation.
Safety interlocks are part of the system solution. For remote support or assistance, this can be provided with SA Power Edge-Control.
Cold Forging automation
The automation required parts to be placed and removed at 30 pres cycles per minute.
The unique system used CAM profiles to ensure motion relative to press motion. A wide range of safety interlocks to prevent tolling crashes.
