The innovative #sinamics#G220 variable frequency drive from Siemens not only helps reduce harmonics (Gary Wilcock) but is also a more sustainable drive choice. Let us explain.
The animation below shows the draft panel layouts for 8 drives using the #G120 drives along with the required input and output reactors due to the long cable lengths involved for this installation.
Shown on the right of the animation is the draft layout using the new #G220 drives.
The new #G220 drives, allow us to accommodate double the number of drives in one cabinet as no chokes are required.
Not only have we have reduced #CO2 emissions in transit as the cabinet is lighter, we have also reduced the amount of #minerals required to build by avoiding additional #copper in the line chokes and #steel in the chokes and cabinets.
The fusing for the other 8 drives has been moved to an adjacent cabinet where there are other drive sizes located. The control panel build is now underway.

A coating machine installed in 1988 was facing increasing reliability and operational challenges due to its age. Key issues included:
Unpredictable Start-ups: The machine suffered from erratic start-ups, impacting the consistency of production
Frequent Recalibrations: Maintenance required regular recalibration of controls to maintain system reliability
Obsolete Motor Components: The DC ATEX-certified motors were no longer available on the market, and existing units were becoming increasingly unserviceable.
High Energy Losses in Transmission: High energy losses occurred due to inefficient PIV transmissions and aging gearboxes
Solution:
The customer needed a comprehensive solution to address the following:
Motor Obsolescence: Replace outdated motors to improve operational reliability and reduce unpredictable start-ups.
Improved Product Quality: Frequent poor coating quality, wrap-ups, and web breaks needed to be minimized.
Flexibility in Production: The upgraded system should be versatile enough to accommodate various products without requiring extensive reconfiguration.
Full PROFISAFE Integration: The machine was eqipped with a full PROFISAFE solution that incorporated safe speed monitoring. This improved operational safety and reducing risks during maintenance and production changes.
Benefits: Following the upgrade, the machine achieved several substantial improvements, making it one of the most energy-efficient unit in the factory, even outperforming newer equipment.
Key benefits included:
Enhanced Energy Efficiency: The new servo motors and optimized drive system minimized energy waste, eliminating the need for ventilation or purging, which reduced fan energy consumption.
Increased Production Speed: The upgraded machine operates at a higher production speed without compromising product quality, resulting in improved throughput.
Reduced Mainternance Requirements: The new configuration eliminated the need for regular recalibration, easing the workload on maintenance staff.
Improved Operator Satisfaction: Operators appreciated the simplified “one-touch” start functionality, which made operation straightforward and reduced the likelihood of errors.
Minimized Product Losses: By eliminating web breaks and improving coating consistency, the machine reduced material waste and product rework.
This comprehensive machine upgrade resulted in a safer, more energy-efficient, and flexible production process, meeting the customer’s needs for reliability, flexibility, and operational efficiency. With improved equipment uptime, increased production speed, and lower energy costs, the customer has a future-proofed machine that supports long-term productivity and cost savings.

Microtach encoders, manufactured by SSD Drives for many years offered reliable transmission of sensitive high-frequency information in an electrically noisy environment.
The technology used a combination of an incremental encoder disk combined with micro-electronics to facilitate the use of single fibre optic transmission of the encoder pulses.
This gave a huge advantage of being able to transmit a noise-free signal over considerable distances.
However, time moves on and the Microtach is no longer available. The fibre optic cable, sending and receiving optics also degrade over time, affecting system integrity and reliability.
Fortunately, Optima can upgrade your ageing Microtach units with a modern equivalent that has exactly the same mounting arrangement. We also supply a new coupling with every encoder.
We use our own proven high-quality multi-sheathed cable to give the same reliable signal quality for the wired encoder equivalent. Distances up to 100 metres have been achieved with no signal degradation.
For this, or any other LINK hardware or software support, just get in touch. With over 100 years of combined experience engineering (and for some, designing!) the Link hardware, we have a solution for your obsolete hardware.

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.
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.
