Mechanical Brake Control Application (ASFIFF17 V 1.11 or higher)
1. INTRODUCTION
Select the Mechanical Brake Control Application ASFIFF17 in menu M6 on page S6.1 .
The Mechanical Brake Control Application is typically used in applications where brake control is
needed.
The hardware can be any Vacon NXS or NXP frequency converter. In closed loop motor control mode
NXP drive and encoder option board is required (NXOPTA4 or NXOPTA5).
All outputs are freely programmable. Digital input functions are freely programmable to any digital
input. Start forward and reverse signals are fixed to input DIN1 and DIN2 (see next page).
Additional functions:
•Programmable Start/Stop and Reverse signal logic
•Reference scaling
•One frequency limit supervision
•Second ramps and S-shape ramp programming
•Programmable start and stop functions
•DC-brake at stop
•One prohibit frequency area
•Programmable U/f curve and switching frequency
•Autorestart
•Motor thermal and stall protection: Programmable action; off, warning, fault
•Mechanical brake control related parameters
•8 digital speed references selected by 3 digital inputs
•FWD and REV Safe speeds activated by digital inputs (NC)
•FWD and REV end limit stops (NC)
•Speed limit with programmable digital input

2. PROGRAMMING PRINCIPLE OF THE DIGITAL INPUT SIGNALS
The programming principle of the input signals in the Mechanical brake control Application as well as
in the Multipurpose 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 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 that the operator defines a certain input for
(see Figure 1).

PROGRAMMING PRINCIPLE OF THE DIGITAL INPUT SIGNALS vacon • 5
2.1 Defining an input for a certain function on keypad
Connecting a certain function (input signal) to a certain digital input 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.

Example: You want to connect the digital input function
Fault Reset (parameter 2.2.7.1) to a digital
input A.3 on the basic board NXOPTA1, located in Slot A.
First find the parameter 2.2.7.1 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) and on the right, digital input
where function is connected.
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 Ato
Eand the I/O numbers from 1to 10.
Once you have set the desired value, press the
Enter button once to confirm the change.

2.2 Defining a certain function with NC_Drive 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 2).

Note: Two inputs s gnals can be connected to same digital input. Use this feature very
considerably.
