1. GENERAL INFORMATION

VACON® NX range embodies a wide selection of expander and adapter boards with which the
available I/O of VACON

®

NX AC drive can be increased and its versatility improved.

The input and output configuration (I/O) of VACON

®

NX is designed with modularity in mind. The
total I/O is comprised of option boards, each having its own input and output configuration. The
boards contain not only normal analogue and digital inputs and outputs, but also fieldbuses and
additional application-specific hardware.

The basic, expander and adapter boards are placed in the board slots on the control board of the AC
drive. The I/O boards are usually interchangeable between different VACON

®

types, i.e. NXS and
NXP. However, the control boards of these types differ from each other to some extent which means
that the use of some I/O boards in different VACON

®

AC drive types may be restricted.

1.1 Board slots on the control board of VACON® NXS and NXP

Figure 1. Board slots on control board of the VACON® NXS and NXP

The control board is situated inside the control unit of the VACON

®

NX AC drive. There are five board
slots (labelled A to E) on the control board of NXS and NXP (See NXS/P User Manual): The
connectability of different option boards to different slots depends greatly on the type of the board.
For more information on this, see Chapter 1.2. See also the descriptions of the options boards on
pages 18 to 79.

Usually, when the AC drive is delivered from the factory, the control unit includes at least the
standard compilation of two basic boards (I/O board and relay board) which are normally installed
in slots A and B. The I/O boards mounted at the factory are indicated in the type code of the AC drive.
The three expander slots C, D and E are available for different option boards i.e. I/O expander
boards, fieldbus boards and adapter boards.

1.3 Option board types

The VACON® option boards are divided in four groups according to their characteristics: types A, B,
C and D. Short descriptions of the types below:

OPTA_

• Basic boards used for basic I/O (NXS, NXP); normally pre-installed at the factory.

• This board type uses slots A, B or C.

See pages 17 to 49 for a detailed presentation of the boards of this type. See also the principle
diagram on the options boards and their equipment on page 81.

OPTB_

• Option boards used for I/O expansion.

• Normally pluggable into slots B, C, D and E.

See pages 53 to 64 for a detailed presentation of the boards of this type. See also the principle
diagram on the options boards and their equipment on page 81.

OPTC_

• Fieldbus boards (e.g. Profibus or Modbus).

• These boards are connected to slots D and E.

See a separate manual on each individual Fieldbus Board. Ask factory or your nearest distributor
for more information.

OPTD_

• Adapter boards

• Boards with fiber optic adapters, e.g. System Bus Fiber Optic Adapter Board.

• Connect the adapter boards to slots D and E (see however page 77).

See pages 69 to 79 for a detailed presentation of the boards of this type. See also the principle
diagram on the option boards and their equipment on page 81.

1.4.1 Isolation

The control connections are isolated from the mains potential and the I/O ground is connected
directly to the frame of the AC drive. Digital inputs and relay outputs are isolated from the I/O
ground. For digital input arrangements, see Chapter Digital input signal conversions on page 7.

1.4.2 Analogue inputs (mA/V)

Analogue inputs of I/O boards can be used as either current inputs or voltage inputs (see detailed
description of each board). The signal type is selected with a jumper block on the board. In case the
voltage type input is used you still have to define the voltage range with another jumper block. The
factory default value for the analogue signal type is given in the description of the board. For detailed
information, see the description of the board in question.

1.4.3 Analogue outputs (mA/V)

In the same way as in the analogue inputs, the output signal type (current/voltage) can be selected
with jumper except for some expander boards with analogue outputs used only with current signals.

1.4.4 Control voltage (+24V/EXT +24V)

The control voltage output +24V/EXT+24V can be used in two ways. Typically, the +24V control voltage
is wired to digital inputs through an external switch. The control voltage can also be used to power­up external equipment, such as encoders and auxiliary relays.

Observe that the specified total load on all available +24V/EXT+24V output terminals must not
exceed 250mA. The maximum load on the +24V/EXT+24V output per board is 150mA. See Figure 3.

Figure 3. Maximum loads on +24V/EXT+24V output

The +24V/EXT+24V outputs can further be used to externally power-up the control board as well as
the basic and expander boards. If an external power supply is connected to EXT+24V output, the
control board, basic boards and expander boards remain live even if mains is lost on the AC drive.
This ensures sufficient functioning of the control logic (not the motor control, however) and some
alarms in exceptional power-loss situations. Furthermore, fieldbus links remain powered which
enables e.g. the Profibus Master to read valuable data on the AC drive.
NOTE: The power unit is not powered through the EXT+24V and therefore the motor control does not
work if the mains is lost.

Requirements for an external power back-up:

- output voltage +24DC±10%, max. ripple voltage 100mV RMS

-max. current 1A

- 1A external fuse (no internal short-circuit protection on the control board

NOTE: Analogue outputs and inputs do not work with only +24V supplied to the control unit.
If there is a +24V/EXT+24V output on the board it is short-circuit protected locally. If one of the +24V/

EXT+24V outputs short-circuits, the others remain powered because of the local protection.

1.4.5 Digital input signal conversion

The active signal level depends on which potential the common input CMA (and CMB if available) is
connected to. The alternatives are +24V or Ground (0V). See Figure 4, Figure 5 and Figure 6.

The 24-volt control voltage and the ground for the digital inputs and the common input (CMA) can
be either internal or external.

Some typical input signal conversion examples are shown below. If you use the internal +24V from
the AC drive, the following arrangements are possible:

If you use an external +24V the following arrangements are possible:

Figure 5. Positive logic with external +24V when CMA is isolated from GND using onboard jumper. The

input is active when the switch is closed

Figure 6. Negative logic with external +24V when CMA is isolated with onboard jumper. The input is active

when the switch is closed (0V is the active signal)

You can make the positive and negative logic arrangements also with the internal +24V. Place the
jumper block in the 'CMA isolated from GND' position (as above) and wire the CMA terminal to the
GND terminal of the AC drive.

1.5 Hardware protections

1.5.1 Terminal block coding

In order to avoid incorrect connections of terminal blocks to boards, some terminal blocks as well
as related terminal connectors on the board are uniquely coded. For more information, see the
description of the individual board.

1.5.2 Board slot guides and allowed slots

You cannot mount an option board into any slot.Table 46 and Table 47 show which slots are allowed
for which option boards. For reasons of safety, slots A and B are protected in hardware against
mounting of unallowed boards. As regards mounting of unallowed boards into slots C, D and E, the
boards just will not work, there is no danger of health or equipment damage.

Local contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/

1.6 Type identification number

NOTE: This information is relevant only for special applications designers using the VACON®
NC1131-3 engineering tool.

Each VACON

®

OPTxx board has a unique type designation code. Besides the type designation code,
each board has a unique Type identification number which is used by the system program to identify
which board is plugged into which board slot. The system program and the application use the Type
ID also to establish the needed connections in order to achieve the desired functionality of the
available I/O boards in the control unit. The ID code is loaded in the memory of the board.

1.7 Defining functions to inputs and outputs

How to connect functions and the available I/O depends on the application you use. The VACON® All
in One Application Package includes seven applications: Basic Application, Standard Application,
PID Control Application, Multi-Step Speed Control Application, Local/Remote Control Application,
Pump and Fan Control Application with Autochange and Multipurpose Control Application (see All­in-One Application Manual). All but two applications of these use the conventional VACON

®

method
to connect functions and the I/O. In the Function to Terminal Programming Method (FTT), you have
a fixed input or output that you define a certain function for. The mentioned two applications, Pump
and Fan Control and Multipurpose Control Application, however, use the Terminal to Function
Programming Method (TTF) in which the programming process is carried out the other way round:
Functions appear as parameters which the operator defines a certain input/output for.

Connecting a certain input or output to a certain function (parameter) is done by giving the
parameter an appropriate value, the address code. The code is formed of the Board slot on the
VACON

®

NX control board (see page 2 and 3) and the respective input/output number. See below.

Example: You use the Pump and Fan Control Application. You want to connect the digital output
function Reference fault/warning (parameter 2.3.1.7) to the digital output DO1 on the basic board
OPTA1.

First find the parameter 2.3.1.7 on the keypad. Press the Menu button right once to enter the edit
mode. On the value line, you will see the terminal type on the left (DigIN, DigOUT, An.IN, An.OUT)
and on the right, the present input/output the function is connected to (B.3, A.2 etc.), or if not
connected, a code 0.#.

When the value is blinking, hold down the Browser button up or down to find the desired board slot
and input/output number. The program will scroll the board slots starting from 0 and proceeding
from A to E and the I/O numbers from 1 to 10.

Once you have set the desired code, press the Enter button once to confirm the change.

1.8 Defining a terminal for a certain function with NCDrive
programming tool

If you use the NCDrive Programming Tool for parametrizing you will have to establish the
connection between the function and input/output in the same way as with the control panel. Just
pick the address code from the drop-down menu in the Value column (see Figure 8 below).

Figure 8. Screenshot of NCDrive programming tool; Entering the address code

NOTE: The inputs, unlike the outputs, cannot be changed in RUN state.

Be ABSOLUTELY sure not to connect two functions to one and same output

in order

to avoid function overruns and to ensure flawless operation.

1.9 Option board related parameters

Some of the input and output functions of certain option boards are controlled with associated
parameters. The parameters are used to set the signal ranges for analogue inputs and outputs as
well as values for different encoder functions.

The board-related parameters can be edited in the Expander Board Menu (M7) of the control
keypad.

Enter the following menu level (G#) with the Menu button right. At this level, you can browse through
slots A to E with the Browser buttons to see what expander boards are connected. On the lowermost
line of the display you also see the number of parameters associated with the board. Edit the
parameter value as shown below. For more information on the keypad operation, see VACON

®

NXS/

P User Manual. See Figure 9.

I/O terminals on OPTA4 (coded terminal painted black)

Description:

Encoder board for VACON

®

NXP. Encoder input board with programmable

control voltage for an encoder.

The encoder board OPTA4 is for TTL type encoders (TTL, TTL(R)) providing

input signal levels that meet the RS_422 interface standard. Encoder inputs

A, B and Z are not galvanically isolated. The OPTA4 board includes, too, the

qualifier input ENC1Q (meant to trace the Z-pulse in certain situations) and a

special/fast digital input DIC4 (used to trace very short pulses). These two

inputs are used in special applications.

The TTL type encoders do not have an internal regulator and use therefore a

supply voltage of +5V±5% whereas the TTL(R) type encoders have an internal

regulator and the supply voltage can be e.g. +15V±10% (depending on the

encoder manufacturer).

Allowed slots: C
Type ID: 16692
Termi nal s: One terminal block; Screw terminals (M2.6); Coding in terminal #3.
Jumpers: 2; X4 and X2 (see page 25)
Board parameters: Yes (see page 27)
