High-frequency drive users: are you breaking the law?

The amended legislation came into force in the EU in December 2014 and, among other things, concerns the supply of HF-capable drives - for example, drives capable of producing an output frequency of greater than 600Hz. Regulations controlling the export of high-frequency drives are already in force in the USA, and similar regulations were introduced to China earlier in 2015.

In order to comply with the new legislation, businesses that export goods or machines that incorporate goods controlled under the terms of the EU Dual-Use Regulation to locations outside the EU must apply for the relevant export licences from their respective governments. The changes also have an effect on the documentation required in any transaction, as well as the measures taken to securely store the controlled goods.

Sanctions for non-compliance

Potential sanctions for failing to comply with the legislation range from financial penalties through to trade restrictions and even prison sentences for individuals. Exporting controlled goods without suitable authorisation is a customs offence.

High-frequency drives

High-frequency drives are used in a number of applications, including automotive testing, turbine test benches and grinding, where speeds in excess of those which can be achieved by a 'standard' variable speed drive (VSD) are required. However, as well as civilian applications, drives operating at higher output frequencies can also be used in the process of refining nuclear materials, hence the stricter export controls brought in with the amended legislation.

Emerson Industrial Automation, of which Control Techniques is a business unit, is keen to advise OEMs and machine builders that incorporate HF drives in their designs that it is they, not the drives manufacturer, who are responsible for checking and evaluating whether or not their machines comply with or contravene the relevant legislation. It is also important for businesses to identify whether any existing machines and systems are affected by the Regulations, as it could affect their ability to export their machines.

Emerson is keen to help and will inform its customers if the drives they purchase appear on the controlled list, but is still advising people to educate themselves on the changes to the export regulations and the ways in which their businesses may be impacted.

Restricted frequency for standard drives

The business took the step of limiting the frequency of the majority of its drives in anticipation of the new legislation. The Control Techniques Unidrive M range was limited to 550Hz at its introduction in 2012, and older drive models have also been revised to be limited to 550Hz. Servo and DC drives are not affected.

In anticipation of the new legislation, Control Techniques has specifically developed a range of HF drives to meet the requirements of the civilian applications that are an important part of its business.

Enrique Minarro Viseras, president of Control Techniques, states: "It is crucial businesses are aware of the amendments to the dual-use legislation. We pride ourselves on our ability to make things as easy and trouble-free as possible for our customers, and have worked hard to ensure our products and processes comply with the new legislation.

"We would urge other businesses to investigate the extent to which they are liable and take the appropriate steps to ensure full compliance."
