4. PRINCIPLE
The programming principle of the input and output signals in the Multipurpose Control
Application NXP as well as in the Pump and Fan Control Application (and partly in the
other applications) is different compared to the conventional method used in other Vacon NX
applications.
In the conventional programming method,
Function to Terminal Programming Method (FTT),
you have a fixed input or output that you define a certain function for. The applications
mentioned above, 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. See
Warning
on page 11.
4.1 Defining an input/output for a certain function on keypad
Connecting a certain input or output with a certain function (parameter) is done by giving the
parameter an appropriate value. The value is formed of the
Board slot
on the Vacon NX
control board (see Vacon NX User's Manual, Chapter 6.2) and the
respective signal number
,
see below.
Function name
Slot Terminal number
Terminal type
Example: You want to connect the digital output function
Reference fault/warning
(parameter 2.3.3.7) to the digital output DO1 on the basic board NXOPTA1 (see Vacon NX
User's Manual, Chapter 6.2).
First find the parameter 2.3.3.7 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 value (0.#).
When the value is blinking, hold down the
Browser button up
or
down
to find the desired
board slot and signal number. The program will scroll the board slots starting from 0 and
proceeding from A to E and the I/O selection from 1 to 10.
Once you have set the desired value, press the
Enter button
once to confirm the change.
