The robust design
incorporates effective protection against supply
network disturbances. Trip-free operation is also
guaranteed due to sophisticated motor control
principles and motor/drive protection features,
component selection and effective cooling.
The reliable choice
Enclosure classes of
IP21 and IP54 and integrated high-level EMC filters
make the Vacon NXS suitable for all environments.
The Start-Up Wizard
and the standard All-In-One Application Package make
parameter setting extremely easy in all cases, from
simple to complex.
The wide and flexible
standard I/O and option for five I/O boards provide
versatile controllability. The most common fieldbus
options are also available.
The modular design of
the Vacon NXS brings several advantages: the control
terminals are safely separated from power
terminals,upgrading the control inputs and outputs
is easy and convenient, replacing the cooling fan
(the only regularly replaceable component) is fast,
the display panel can be utilized for parameter
copying, etc.

Design & Dimensions
The mechanical design
is extremely compact. The IP54 units in particular
are the smallest AC drives on the market. All units
are suitable for both wall and enclosure mounting
with all necessary components: integrated EMC fi
lters, AC chokes, cable protection, dust and water
protection. The effective super-cooling principle
allows high ambient temperatures and high switching
frequencies without derating.
Vacon NXS control
unit
There are no fixed
inputs or outputs in the Vacon NXS. There are fi ve
slots (A, B, C, D and E) for I/O boards, and a
suitable board can be selected for each slot.
The NXS units are
delivered with OPT-A1 and OPT-A2 boards if the I/O
is not specified. In many countries, boards OPT-A1
and OPT-A3 are used as standard I/O as the
galvanically (double) isolated thermistor input is
often required.
Removable terminals,
snap-in card installation, automatic card
identification and instructions on the drive help
making quick connections. If necessary, the inputs,
outputs and fieldbus boards can be added in the
field. The Vacon NXS is simply the most flexible
frequency converter series on the market.
An external +24 V
supply option enables communication with the control
unit even if the mains supply is switched off (e.g.
fieldbus communication and parameter settings).
