from 0.25 kW to 5 MW

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

needs, the experienced Vacon personnel is
pleased to assist you in making the right
decision. We know there are several issues
to consider. Therefore, we have the know-how
and willingness to help you to concentrate
on the essentials. |
Dimensioning |
| The load conditions
of your application and the ambient temperature
are the two main factors that affect most
on the correct rating for the drive. |

Performance |
| The speed and torque
accuracy as well as the response times needed
for your application determine the type
of control and the control mode to be used. |
