Vacon excellence from 0.25 kW to 5 MW

The key feature of all Vacon variable speed AC drives is full hardware and software modularity. 

The Vacon concept of modularity is unique. There are three different control units, two cooling methods for power units, room for five different I/O cards and field-installable conversion kits, just to name a few. These elements can, to a degree, be mixed and matched.

The Vacon NXS and NXP control units can be detached from the power units and mounted elsewhere. The NXS control is designed for typical industrial applications that do not require the precision provided by a feedback device. The NXP control can use an encoder feedback to deliver the ultimate motor control performance.

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

The I/O cards can be used in all three drive types: one I/O card in the NXL to expand the basic I/O, and up to five I/O cards in the NXS and NXP to create the necessary I/O configuration for your application.

The NXL has a detachable, remote-operation seven-segment LCD keypad without memory capabilities. It is used to communicate with the drive, set parameters and for monitoring.

The NXS and NXP have a detachable, remote-operation alphanumeric keypad with built-in memory. It is used to communicate with the drive, set parameters and for monitoring. It can be used to copy parameters between different drives. It is capable of storing the active parameter set automatically for future use.

The Vacon NX control units are usually supplied by the power unit. The control unit can be powered from an external 24 V supply, making it possible to use the fieldbus communications and to read data even when the main supply is off.
