The drive is equipped with a wide range of industry features that enable optimal process control, higher quality output, and reduce costs related to spare parts and service.

Free to equip

The VLT® AutomationDrive EZ can optimally control nearly all standard industrial motor technologies, including Asynchronous, IPM, SPM, Synchronous Reluctance, and PM assisted Synchronous Reluctance motors. This means that system designers, OEMs, and end-users are free to connect the drive to their selected motor and remain confident that the system will perform to the highest possible standards.

As an independent manufacturer of AC drive solutions, you can count on Danfoss to support all commonly used motor types and foster ongoing development as new technologies emerge.

Speaks your language

When it comes to working with advanced technologies, such as AC drives, it is fairly easy to feel lost while navigating through hundreds of parameters. Using a graphical interface makes this process much easier, especially when it lists parameters in your native language.

Additionally, the ability to save up to 50 user-selectable parameters further simplifies interactions with key parameter settings for your unique application.

Automatic adaption to application

Around 90% of all motors are oversized by more than 10%. Automatic Energy Optimizing (AEO) functionality can deliver energy savings of 2-5% over the whole load range.

Advanced Automatic Motor Adaption

The VLT® AutomationDrive EZ will automatically adapt to the motor to ensure supremely efficient motor performance, no matter which brand or type of motor technology you choose for your facility. The VVC+ output switching algorithm and FLUX control automatically perform advanced motor data analysis for optimum and highest efficiency of control.

Designed for a minimum of 10 years' lifetime

With the VLT® AutomationDrive EZ high-quality components, maximum 80% load on components, and intelligent heat management minimizing dust on PCBs, the need for routine scheduled replacements of parts, such as electrolytic capacitors and fans, has been removed.

Reduce costs with compact drives

A compact design and efficient heat management enable the drives to take up less space in control rooms and panels, thereby reducing initial costs. Compact dimensions are also an advantage in applications where drive space is restricted, making it possible for designers to develop smaller applications without being forced to compromise on protection and grid quality. For example, VLT® AutomationDrive EZ FC 321 in a D enclosure size is 25-68% smaller than equivalent drives.

Despite the compact dimensions, all units are nevertheless equipped with integrated DC link chokes and EMC filters, which help to reduce grid pollution and reduce cost and efforts for external EMC components and wiring.

The Chassis version is optimized for side-by-side mounting in cabinets to 122°F without derating and features covered power terminals to prevent accidental contact. The AC drive can also be ordered with an optional brake chopper in the same package size. Control and power cables are fed in separately at the bottom.

The AC drives combine a flexible system architecture that allows them to be adapted to specific applications, with a uniform user interface across all power classes. This allows you to adapt the drive to the exact needs of your specific application. As a result, project work and costs are subsequently reduced. The easy-to-use interface reduces training requirements. The integrated SmartStart guides users quickly and efficiently through the set-up process, resulting in fewer faults due to configuration and parameterization errors.
