Configuring the Vacon NX Frequency
Converter (NXVFD)
VACON NX frequency converter (NXVFD) is an electronic
device for control of speed and torque of three-phase
alternating current (AC) motors. NXVFD converts the fixed
frequency and voltage of the main supply (mains) to a variable
frequency and voltage, which can then be regulated to provide
flexible motor operation and reduce energy consumption.
VACON NX frequency converters can be connected to the
LonWorks network using a field bus board.
The VACON NXOPTC4 option board is equipped with an
FTT-10A transceiver supporting the Free Topology
transformer coupled network, which allows the network wire to
be connected as bus, star, loop or combination of these. The
converter can then be controlled, monitored and programmed
from the Host system. The LonWorks board shall be installed
in slot E on the control board of the frequency converter. The
converter can then be controlled, monitored and programmed
from the LONWORKS network.
Configuring NXVFD settings
IMPORTANT NOTE:
After the option card is installed, it is mandatory to
make the following settings for Control Place and
Frequency Reference:
1.
Selection of Control Place –
The NXVFD device can be controlled from three
different places. They are (default control place is Key
Pad [panel]):
• I/O terminal
• Key Pad (panel)
• Fieldbus
The Key Pad control of NXVFD device is used for
parameter setting, reading status data and giving control
commands.
The NXVFD has to be configured to select field bus as
control place before starting any of the operations
through the wizard. This configuration can be performed
using the Key Pad control provided along with device as
follows:
• In the keypad, from the main menu, select the menu
called Keypad Control.
• Select the submenu Control Place and set it to
FieldBus
.
NOTE: None of the values sent (through fieldbus), by the
wizard will be considered until and unless the device
is configured with field bus as control place.
2.
Selection of Frequency Reference –
The NXVFD can be configured to select the frequency
reference from following different sources:
• AI1
• AI2
• Keypad
• Fieldbus
• Configuring VFD NX Drive parameters

This list is by default filled with the same
options as Default Assignment. But, the
user has an option to change the outputs.
