1.5.2 BICO technology: example
Example: Shifting a basic PLC functionality into the inverter
A conveyor system is to be configured in such a way that it can only start when two signals
are present simultaneously. These could be the following signals, for example:
● The oil pump is running (the required pressure level is not reached, however, until after
five seconds)
● The protective door is closed
The task is realized by inserting free blocks between the digital input 0 and the internal ON
command for the motor and interconnecting them.

Parameter Description
P0003 = 3 Enable expert access to parameters
P0700 = 2 Select the command source: Digital inputs
P0701 (e.g.) = 99 Enable/"open" digital input 0 (DI0) for BICO parameterization
P0702 (e.g.) = 99 Enable/"open" digital input 1 (DI1) for BICO parameterization
P2800 = 1 Group enable all freely-programmable function blocks (FFB)
P2801 [In000] = 1 Individual enable of the AND function block
P2802 [In000] = 1 Individual enable of the TIMER function block
P2850 = 5.0 Set the TIMER delay time: 5 seconds
P2849 = r0722.0 Connect the status of DI0 to the TIMER input
r0722.0 = Parameter that displays the status of digital input 0.
P2810 [In000] = r2852 Connect the TIMER output to the 1st input of the AND
P2810 [In001] = r0722.1 Connect the status of DI1 to the 2nd AND input
r0722.1 = Parameter that displays the status of digital input 1.
P0840 = r2811 Connect the AND output to the control command ON/OFF1
