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
● 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.
