Yaskawa’s Sigma-7 – latest generation servo drives.

10 July 2024

With over 18 million servo systems deployed in the industry, Yaskawa has a combination of years of experience and expert know-how in the field of motion control. The result is the excellent efficiency and performance of each system and an extremely low failure rate.

With its current Sigma-7 series of servo drives, the company is present on the market with a true masterpiece in terms of precision and reliability. Thanks to its advanced features, this latest generation product line allows for quick and hassle-free installation in just a few minutes. It also allows for easy, application-specific settings that ensure maximum utilization of the servo technology’s potential.

The development of Sigma-7 is focused on three main goals: fast commissioning, high performance and maximum operational reliability.

The models of the series are specially designed to meet the requirements of both machine-building enterprises and end-users in the manufacturing sector. Yaskawa servo drives have particular potential to shine in product packaging, semiconductor manufacturing, woodworking and printing applications.

Intuitive. Hurry up. Reliable.

Among the advantages of Sigma-7 is the quick setup within just 3 minutes thanks to the pre-configured modules in the software installation assistant.

The direct commissioning function allows immediate use of the servo drive without the need for complex parameterization or specialist knowledge in the field. There is also an auto-configuration feature that allows the system to quickly and autonomously adapt to the application’s requirements.

Another advantage of the Sigma-7 is its space-saving capabilities in the control cabinet. The new housing design allows for side-by-side mounting of the drivers without gaps between them. Thus, the total required space is reduced to a minimum.

A key benefit of choosing the new servo drives is their high environmental efficiency. The high efficiency of the Sigma-7 motors reduces the amount of heat generated by up to 20%, and the DC Bus power sharing technology allows for a reduction of the total power consumption by up to 30%.

Sigma-7 reduces total costs by providing faster commissioning, higher productivity with more products in less time and reduced machine downtime due to its high reliability.
