5.6.3.7 Setting the free function blocks (FFBs)
Functionality
Additional signal interconnections in the converter can be established by means of the free
function blocks (FFBs). Every digital and analog signal available via BICO technology can be
routed to the appropriate inputs of the free function blocks. The outputs of the free function
blocks are also interconnected to other functions using BICO technology.
Example
Setting parameters
Parameter
Function
Setting
P0702
Function of digital input 2
= 99: Enable BICO parameterization for digital input 2
P0703
Function of digital input 3
= 99: Enable BICO parameterization for digital input 3
P2800
Enable FFBs
= 1: Enable (general enable for all free function blocks)
P2801[0]
Activate FFBs
= 1: Enable AND 1
P2810[0]
BI: AND 1
= 722.1
P2810[0] and P2810[1] define inputs of AND 1 element, and
output is r2811.0.
P2810[1]
= 722.2
P0731 BI: Function of digital output 1 This parameter defines source of digital output 1.
= r2811.0: Use the AND (DI2, DI3) to switch on LED
For more information about FFBs and additional settings of individual parameter, see
Chapter "Parameter list (Page 193)".
