Figure 6-14
The technology controller specifies the speed setpoint of the motor in such a way that the
process variable to be controlled corresponds to its setpoint. The technology controller is
designed as a PID controller, which makes it highly flexible.
The technology controller setpoint can be supplied via the same setpoint sources as those
available for the speed setpoint. The technology controller is also equipped with its own
motorized potentiometer and own fixed frequencies.
The setpoints, actual values, and control signals of the technology controller are defined by
means of BICO technology.

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:
