Because of their superior functionality, comprehensive performance range and application flexibility, the Siemens Simovert MASTERDRIVES in CUVC, CUMC, Compact form and other variants has been a very successful drive system for single motor and multi-motor applications. The established common DC bus system enabled it to be used on demanding production machine processes across a wide range of industry sectors.
All good things must come to an end, but that doesn’t mean the end of the line for your production machine.
Optima’s innovative approach to upgrades significantly reduces the installation time and minimises risk to your site. All of our systems are thoroughly tested before they are shipped to site, completely eliminating any “out of box” failures.
Some of the benefits you will realise are:
Extended life span of your machine and increased availability due to continued spare parts supply with full support by Siemens
Improved productivity through lower energy costs and faster production cycles, through:
Simple operation monitoring using operator panel
User-friendly diagnostics with the STARTER tool
Additional interface options via PROFINET or PROFIBUS
Future-proofed due to access to the new world of TIA Portal
Optima’s approach for upgrades is to:
1.Analysis of your current machine configuration and potential further customer request
Recommendation on the best replacement scenario
Installation, configuration and commissioning of new components and creation of circuit diagram and documentation
Acceptance test and machine handover.
If requested, we can also provide training for all your relevant engineers and instruction of the operating personnel
We’ve been upgrading complex drive systems for over 20 years
We are one of only 7 authorised Siemens Drives and Motion partners in the UK
We provide a complete solution provided by one retrofit supplier including mechanical installation of motors and/or supply of adaptor plates and flanges to suit
When a major paper producer was faced with increasingly temperamental performance from the existing hydraulic drive control system on their Valmet KL Winder, they turned to Optima for assistance. The system suffered from uncontrolled starting from cold until the hydraulics had reached normal temperature. However, even at normal operating temperature, there were still issues with tension control being unpredictable.
Optima were asked to suggest possible upgrade solutions for the winder. Our solution was to use a Siemens Sinamics drive system, controlled from our own custom-written winder blocks. Optima’s winder blocks are PLC-based and provide all the functionality required of any winding application.
The new drive system was specifically designed to suit the exact material tensions, roll diameters and operating speeds of the winder to ensure both performance and cost needs were met. The actual products run on winders sometimes differ from the manufacturers own design.
A complete new control suite was built to house the new PLC and drive hardware. Installation was managed by Optima.
Final Commissioning was carried out by our own engineers specialising in web transport systems.
Tuning of the fully-compensated system was carried out over a series of product trials on different grades of paper. The drive control system is complex, not just for accurate tension control but also to drive either end of the paper unwind with separate AC geared motors – not an easy task to achieve. Optima’s control algorithms ensure that control of the unwind reel is shared equally between each drive whilst also preventing ‘slippage’ of the driving mandrel within the unwind core.
Optima will be pleased to provide a no-obligation site visit to discuss how we might improve the performance of your existing winder or for a completely new upgrade.

In this upgrade, carried out during a planned shutdown, an Automax controller and obsolete DC drives were removed and replaced by new AC Powerflex 753 drives and AC vector motors. The SLC500 rack was replaced by a new Control Logix rack and remote IO on Ethernet. The now redundant PanelMax HMI was replaced by a new InTouch system from Wonderware.
The full scope of work, carried out by our own engineers in-house included:
Hardware calculations/rating for drives
Customer project specifications for upgrade
Project design specification
Full Circuit diagrams for the upgraded equipment
Test documents to validate the new equipment operation
Software specifications and sequence diagrams
Details of a typical metalliser drive control system are shown below. Optima know the metalliser drives process intricately. We have upgraded over 10 metalliser drive systems from various manufacturers and can offer a comprehensive upgrade to bring control of your machine drive system up to the standards of a new metalliser.
Optima will be pleased to provide a no obligation site visit to discuss how we implemented this upgrade and how we can help upgrade your machine to new supportable equipment.
