About Masterdrives:

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.

Don’t replace old for old. Replace old with new!

Should you really replace like-for-like following failure of an automation component? Why not consider the opportunity of upgrading to a brand new fully-supported unit? The cost difference may not be what you expect. Quite the opposite in fact. Read on for more information: 

When faced with the complete failure of a HMI TP177A, our customer wished to source an equivalent part from the original supplier.

Two problems were:

1) The obsolete screen was programmed with an obsolete package – Protool

2) The cost of the old replacement screen was more expensive than a newer and fully supported HMI.

After analysing the upgrade possibilities Optima were able to solve the two problems of replacement and obsolescence but with a further advantage to the customer.

Optima were able to convert the old HMI configuration to the new HMI equivalent and supply it to the customer for around the same price as the obsolete part.

It is often the case that upgrading hardware can actually work out less in real cost terms than replacing old parts  on a like-for-like basis.

Weekend shutdown sees pump system upgraded to latest Siemens Sinamics drives and S7-1200 PLC

If you are faced with an ageing and obsolete control system but don’t think you have the shutdown time to upgrade, think again. In one weekend, Optima were able to strip out an old motor control set and replace it with the latest state-of-the-art Siemens PLC and Drive control package. Find out how here:

When faced with the unreliability and ageing Crabtree motor starter sets, a leading manufacturer of waterproofing products turned to Optima for assistance. The existing pump control system was direct on-line and required pump changeovers to be initiated manually.

Old Pump Control Starter Panels

The solution was to replace the existing starter panels with a single panel housing 18.5kW and 30kW variable speed drives with a S7-1200 PLC controlling pump changeover from a 4 inch Basic HMI. This display shows providing pump status, hour run and pump selection buttons and also allows the system to run in fully Automatic or Manual modes.

New Pump Control Panel In-Situ

The installation task had to be completed during a weekend shutdown, requiring careful coordination between production and our engineering team to schedule the works.

The system was powered up ready to run in full production before Monday’s switch-on.

First Batch of UL-Control Panels Finished and ready for shipping to the USA

Not content with supplying our UK and European customers with quality control panels from our workshop, we thought to look further afield. Far across the Atlantic Ocean in fact. Optima turned our engineering skills to designing a full process control system for a customer in the USA. Here are some of the panels we built for this project.

This is our first batch of UL-Rated control panels completed and ready for storage prior to shipping to the United States. This is part of a fully integrated Rockwell Automation control system featuring ControlLogix PLC’s with Guard Logix Safety and PowerFlex Drives.

Improved Performance And Reliability Following Upgrade From Hydraulic Motors To AC Geared Motors

Hydraulic motors have their place in industrial controls but when precise speed and torque control are required, they can be wild beasts to tame. With unreliability plaguing one paper mill, followed by complete failure of the hydraulic process control system, Optima were able to step in and provide an upgrade solution in double-quick time.

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.
