Vacon NXS and NXP AC Drives
The modular and robust design combined with the powerful software support for the creation of new applications make the Vacon NX an ideal solution for even the most demanding applications. The wide temperature range, the multilingual control panel that speaks your language and the high reliability make the Vacon NX the drive for the new century.

The Vacon NX provides two different control units, the NXS with a standard open loop sensorless vector control software, sufficient for the majority of applications, and the NXP with a high-performance closed loop control software for most demanding applications.
The design approach of both control units incorporating the same application packages, control panels, I/O cards and PC tools provides unsurpassed ease of use.

The Vacon NXS is designed to be a standard, easy-to-use drive with a wide application area. It is based on an advanced sensorless vector control concept, which gives a very good motor control under all circumstances. An automatic torque maximizer feature is available, ensuring that all loads can be started reliably. It also includes an automatic energy saving feature, which optimizes the motor flux as a function of motor load and speed. The basic drive operation is also suitable for multi-motor applications.

 The Vacon NXP is used in all cases where a very high precision of speed and torque under all circumstances are required. Equipped with high processing power, the NXP can use information from an encoder or a resolver in order to provide very precise motor control. Sensorless vector and normal U/f control are also supported. Typical applications requiring high performance are: master-slave drives, positioning applications, winder tension control, and synchronization.

The power unit of the drive is available in either an air-cooled or a liquid-cooled version.
