Vacon frequency inverter NXL series is easy to plug, and easiest to play

The Vacon NXL is a powerful and compact AC drive for industrial and residential purposes in the power range from 0.25 to 30 kW. The space-saving bookshelf design with high protection classes, versatile control and programming capabilities offer an optimal solution for all operating environments. Installation, connection and commissioning procedures are extremely quick and convenient with instructions attached to the unit. Thanks to an extremely effective design, everything is included as standard. The units can be installed on the wall without additional cabinets because of high protection classes. The RFI filters and brake choppers are always integrated. The standard units fi t almost everywhere in both industrial and residential areas. The integrated AC choke is the most effective way to protect the drive against the overvoltage spikes and to reduce the stress on supply transformers, cables and fuses.

Convenient installation and programming 
The installation and programming is extremely quick and convenient with the help of the credit-card-size Quick Guide. The programming is often just a selection of load type and fi ne-tuning of the motor nominal current and speed. Although the Vacon NXL is simple in construction compared to other Vacon NX ranges, it is the most fl exible drive in its class. The fl exibility means a wide range of control possibilities, programmable features, installation possibilities and modularity. The easy-to-use PC tools can be used e.g. for programming and parameter copying. Sometimes it is possible to remove the PLC from the system by adding logic to the drive with the NC1131-3 PC tool. The double rating of the Vacon NXL and dynamic open loop vector control make the NXL a perfect choice for all kinds of loads, from simple pumps and fans to demanding material handling applications. The motor noise level is extremely low because of a high switching frequency and a near-sinusoidal current waveform. 

More features, more performance 
- No additional cabinets required 
- Everything integrated as standard (dust/water protection, RFI filter, AC choke, brake chopper) 
- Easy to install, easy to use 
- Low noise (both drive and motor) 
- Large amount of control possibilities (via I/Os, field buses or display panel) • Large amount of features (e.g. fully programmable I/O, autoidentification, PID controller, flying start)
-High performance

Vacon drive NXL series control unit

The standard I/O of the Vacon NXL has been optimized for typical control requirements. In addition to digital and analog inputs and outputs, RS485 is included as standard. All inputs and outputs of the standard I/O and option boards are freely programmable. Both Analog Inputs can be programmed for 0...10 V or 0(4)...20 mA signals. Analog Input can also be programmed as Digital Input. The standard I/O can easily and cost-effectively be extended with OPT-AA or OPT-AI boards, if necessary. The OPT-AA is the most effective way to add one more Relay Output, and the OPTAI is normally used when galvanically isolated motor thermistor connection is needed. These boards are installed in option board slot E. It is also possible to control the Vacon NXL with various kinds of fieldbuses with OPT-C-type boards (see the table below). The I/O extension and fieldbus boards are the same for all Vacon NX products. The fieldbus boards can be installed in slot D or E. There are a large number of OPT-B-type option boards available. The most typical boards are included in the table below. It is possible, for instance, to add three more output relays with OPT-B5, if necessary. The OPT-B-type boards are typically installed in slot E.

First-class usability with Vacon vfd NXL series

The basic settings can be programmed by simply launching the Vacon NXL start-up wizard. Only four steps are required, and the drive is ready to run. 

The instructions to install, connect and program the Vacon NXL are included in the credit-card size Quick Guide attached to each unit.

The standard Multi-Control Application software of the Vacon frequency inverter NXL series

The standard Multi-Control Application software of the Vacon NXL is extremely flexible and easy to use. All inputs and outputs are programmable, and there is a full set of features and possibilities for system or process control and protections. The default settings are very close to optimum, and the drive operates accurately enough without any programming. It still is recommended to check and fine-tune the motor nominal values to optimize the performance and motor protection. Programming can be made simply by using the start-up wizard feature of the display panel, programming parameter by parameter with display panel, or programming by the NCDrive tool. The instructions, if required, can be found in the credit-card-size Quick Guide. There are many parameters and features which can be utilized, if necessary. 
For example:
- PID controller 
- Pump and fan control for a maximum of 4 parallel motors 
- Flying start 
- Auto-tuning 
- Programming of all control inputs and outputs 
- Output relay delays
In addition to the standard MultiControl Application software, some special application software is also available. It is even possible to make totally customer-specific software with the NC1131-3 Engineering tool, and remove the PLC by integrating the logic to the NXL software.
