What can I do about my Obsolete Drives?

Free Resilience Report Unveils the Path to Enhanced Performance & Zero Downtime for Obsolete Drives

Variable speed drives (VSDs), are a crucial component in various industrial and commercial applications. These drives enable precise control over the speed and torque of electric motors, resulting in increased energy efficiency and improved process control. However, with the rapid advancement of technology, older VSD models can become obsolete, presenting challenges in terms of maintenance, performance, and compatibility. In this article, we will explore the reasons behind the obsolescence of variable speed drives and discuss what steps should be taken if you have one.

Reasons for Obsolescence

  • Technological Advancements

The field of motor control has witnessed significant technological developments over the years. Newer VSD models offer improved features such as enhanced energy efficiency, advanced motor protection, greater integration capabilities, and better diagnostics. These advancements often render older VSDs outdated and less efficient in comparison.

  • Spare Parts Availability

As VSD models age, manufacturers may phase them out, leading to limited availability of spare parts. Repairing and maintaining an obsolete VSD can become increasingly challenging, as finding compatible components becomes more difficult. This scarcity of spare parts can result in prolonged downtime and increased costs.

  • Support and Service

Manufacturers typically provide support and service for their products within a specific timeframe. As VSD models become outdated, manufacturers might discontinue support or offer limited assistance, making it challenging to obtain technical help or updates for obsolete drives.

  • Safety and Compliance

Safety standards and regulations evolve over time to address new risks and enhance workplace safety. Older VSDs might not comply with the latest safety standards, potentially posing safety hazards and making it difficult for businesses to meet regulatory requirements.


What Do I Do If I Have an Obsolete VSD?

  • Evaluate the Impact

Begin by assessing the impact of the obsolete VSD on your operations. Consider factors such as performance, energy efficiency, maintenance costs, spare parts availability, and safety compliance. Determine whether the outdated drive is negatively affecting your productivity or increasing long-term expenses.

  • Consult with Experts

Seek advice from professionals or experts in the field of motor control. They can evaluate your current VSD setup, assess its compatibility with newer technologies, and offer recommendations based on your specific needs. They may suggest retrofitting options or upgrading to a modern VSD system.

  • Retrofitting

In some cases, retrofitting an obsolete VSD can be a cost-effective solution. Retrofitting involves replacing critical components of the drive while retaining the existing infrastructure. This process can help extend the lifespan and enhance the performance of your VSD, while also incorporating some of the latest features and technologies.  It is important to make sure you are dealing with a qualified company who are experts at dealing with drives.

  • Upgrading to a Modern VSD

If the costs and limitations associated with retrofitting outweigh the benefits, it may be more prudent to consider upgrading to a new, modern VSD. A new VSD can provide improved efficiency, reliability, and enhanced features. However, upgrading may require additional investment and downtime during installation and commissioning.  There is however, an alternative, if you are unable to come up with the capital to purchase a new VSD, you could hire one in.  Ay company hiring you a VSD should maintain and service the application, which will save your engineering resources.  At Quantum, we have round the clock access to over 2,500 ABB & Schneider Electric Drives up to 4.5MW power rating, our engineers commission, install and maintain all of our hire VSDs.


As technology continues to advance, it is essential to stay updated and adapt to newer systems that offer improved efficiency, performance, and compliance with evolving standards. If you have an obsolete variable speed drive, carefully evaluate its impact on your operations and consult with experts to determine the best course of action. Whether through retrofitting, hiring or upgrading to a modern VSD, taking proactive steps will help ensure optimal motor control, increased energy savings.
