Logical functions using function blocks

Description
Additional signal interconnections in the inverter can be established by means of free
function blocks. 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. Among others, the
following unassigned function blocks are available:
● AND blocks, OR blocks, XOR blocks, NOT blocks
● Memory elements
Example: OR logic operation
You want to switch-on the motor via digital input 0 and also via digital input 1:
1. To do so, interconnect the status signals of digital inputs r722.0 and r722.1 with the inputs
of a free OR block via BICO.
2. Now activate the OR block.
3. Finally, interconnect the OR block output with the internal ON command (P0840).

Parameters for using the free function blocks
Description
Enable FFBs (General enable for all function blocks)
0: locked
1: enabled
Activate FFBs (activation of the individual function blocks)
Activate fast FFBs (enable an 8ms time slice to calculate the activated, fast function
blocks)
0: All function blocks are calculated with a 128 ms time grid
1: Some of the function blocks can be calculated with an 8 ms time grid.
