Vacon frequency inverters Vacon NXS general industry series

Vacon frequency inverter NXS series is the reliable choice.

VACON® NXS is a compact AC drive in the power range of 0.37—560 kW and supply voltages of 208—690 V for heavy use in machines, buildings and all branches of industry.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. Enclosure classes of IP21 and IP54 and integrated highlevel 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.

Vacon drive NXS series control unit.

There are no fixed inputs or outputs in the VACON NXS. There are five slots (A, B, C, D and E) for I/O boards, and a suitable board can be selected for each slot (see the table below). The NXS units are delivered with OPT-A1 and OPT-A2 boards if the I/O is not specified. In many countries, boards OPT-A1 and OPT-A3 are used as standard I/O as the galvanically isolated thermistor input is often required. Removable terminals, snap-in card installation, automatic card identification and instructions on the drive help making quick connections. If necessary, the inputs, outputs and fieldbus boards can be added in the field. The VACON NXS is simply the most flexible frequency converter series on the market. An external +24 V supply option enables communication with the control unit even if the mains supply is switched off (e.g. fieldbus communication and parameter settings).

Vacon vfd NXS series - first-class usability.

The uncluttered text display panel with a well-defined menu structure and functions such as automatic parameter copy and start-up wizard makes commissioning and fine-tuning as easy as possible.

Vacon PC tools include:
- VACON NCDrive for parameter setting, copying, storing, printing, monitoring and controlling
- VACON NCLoad for software updating and uploading special software to the drive
- VACON® Programming tool is available for making tailor-made software. A license key and training required. 
- The VACON PC tools require only an RS232C cable for communication with the drive (no adapters etc. required).

Vacon frequency inverter NXS series software modularity.

The All-in-One application package has seven applications (=default settings and functionality of control inputs and outputs, see tables below) which can be selected with one parameter. The application will also be requested by the Start-up Wizard at the first power-up. With this single setting, the controls can be programmed e.g. for two external control places or a pressure control with the integrated PID controller. In most cases, the default basic application is suitable and only the min/max frequencies as well as motor nominal values must be set. Thanks to the modular software applications made by the VACON Programming tool (based on IEC 61131 standard), the Allin-One application package can be replaced by the Water application package that contains several applications optimized for water handling. There are also several other general-purpose software applications available.
