Vacon NXL - Compact and Versatile AC Drive The Vacon NXL is a powerful and compact AC drive
for general light industrial and residential purposes in the power range from
0.25 to 30 kW. The space-saving bookshelf design with enclosure options and EMC
features is a drive for all needs. One option card slot provides multifunctional
connections to automation, and good programming capabilities offer an optimal
solution for all operating environments. The smaller-sized MF2 and MF3 units (in the enclosure class IP20) are designed for mounting in a separate enclosure. They can be delivered with DIN rail or screw mounting op- They can be delivered with DIN rail or screw mounting options. The units can be mounted either at the back or at the tions. The units can be mounted either at the back or at the side of the drive. The Vacon NXL can often be taken into use without programming. If necessary, parameter setting is done either via the seven-segment LCD panel or via a PC and the NCDrive software. The Vacon NXL incorporates the standard I/O and an integrated RS485 (Modbus) connector. There is room for one option card with more I/O or some other functionality. Most of the option cards for the NXS/NXP range can be used with the NXL, specifically I/O expansion and fi eldbus cards. The I/O terminal labelling and functionality correspond to those of the NXS/NXP range. Features
Multi-control application as standard The Vacon NXL includes an easy-to-use and flexible multicontrol application. The need for parameter adjustments is control application. The need for parameter adjustments is kept to a minimum, thanks to well-defined default settings. All I/Os can be programmed. The versatile features include:
Vacon NXS 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. Features
Vacon NXP 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 simple frequency control are also supported. Typical applications requiring high performance are: master-slave drives, positioning applications, winder tension control, and synchronization. Features
Vacon NXdrive The Vacon NXdrive is the pre-engineered single-drive enclosure series. It is used for the higher powers, currents from 385 A (380 - 500 V) and from 261 A (525 - 690 V). The basic power units of the larger frames are designed as IP00 modules; therefore an enclosure is always needed. The enclosure can be supplied either by Vacon or by any independent system integrator.
Compact and flexible The NXdrive is a free-standing enclosure for the larger power frames. A large number of pre-designed options are available, typically input (fuses, switches, breakers), output (filters) devices or control options. It is compact and well tested, fully utilizing the modular approach of the drives. In the design process, all requirements related to fl exibility, robustness, compactness and service-friendliness were taken into account, creating a solution suitable for any application. User-friendly The Vacon NXP control unit is physically completely separated from the power module. It is mounted on a separate control compartment at an easily accessible height. The bracket also has space for additional control circuitry, such as relays, or contactors. The power input and output terminals have ample space for cable connection. Floor plates and 360 degree earthing clamps for cable shields are included in the standard delivery. Fully tested All NXdrive enclosures are designed with our long experience on enclosed high-power drives. Special care has been taken with temperature management, guaranteeing a long life for the enclosed drive. The EMC performance is also verified, leading to trouble-free operation in the industrial environment. Service-friendly The NXdrive has been designed to fully exploit the modular design of the high-power NXP drives. The power modules are mounted on extendable rails where needed. This allows easy servicing of the power module in case of need. The larger units consist of smaller phase modules, which can separately be taken out of the enclosure. Easy ordering The NXdrive can incorporate a variety of options such as input fuses, breakers, contactors, switches, and a selection of output fi lters (sine or du/dt). Each option is defi ned by adding an ordering code to the basic enclosure code, again creating a very modular system allowing you to defi ne the exact drive you need.
