The key feature of all Vacon 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.
