Vacon NXS – robust drive for heavy use

The Vacon NXS is a compact AC drive in the power range of 0.75 - 560 kW and supply voltages of 208-690 V for heavy use in machines, buildings and all branches of industry. The double rating of the Vacon NXS and dynamic open loop vector control make the NXS a perfect choice for all kinds of loads.

The robust design incorporates effective protection against supply network disturbances. Trip-free operation is also guaranteed due to sophisticated motor control principles and motor/drive protection features, component selection and effective cooling.

The reliable choice. Enclosure classes of IP21 and IP54 and integrated high-level EMC filters make the Vacon NXS suitable for all environments. The Start-Up Wizard and the standard All-In-One Application Package make parameter setting extremely easy in all cases, from simple to complex. The wide and flexible standard I/O and option for five I/O boards provide versatile controllability. The most common fieldbus options are also available.

The modular design of the Vacon NXS brings several advantages:

• the control terminals are safely separated from power terminals
• upgrading the control inputs and outputs is easy and convenient
• replacing the cooling fan (the only regularly replaceable component) is fast
• the display panel can be utilized for parameter copying, etc.

Design & dimensions

The mechanical design is extremely compact. The IP54 units in particular are the smallest AC drives on the market. All units are suitable for both wall and enclosure mounting with all necessary components:

• integrated EMC filters
• AC chokes
• cable protection
• dust and water protection
• The effective super-cooling principle allows high ambient temperatures and high switching frequencies without derating.
