Siemens SINAMICS G120 CU240B-2 - BICO Technology: Example

Introduction

What sources of information do you need to help you set parameters using BICO
technology?
● This manual is sufficient for simple signal interconnections, e.g. assigning a different
significance to the to digital inputs.
● The parameter list in the List Manual is sufficient for signal interconnections that go
beyond just simple ones.
● You can also refer to the function diagrams in the List Manual for complex signal
interconnections.
1.6.2 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/OFF1 command and interconnecting them.

Figure 1-4 Example: Signal interconnection for interlock
The signal of digital input 0 (DI 0) is fed through a time block (PDE 0) and is interconnected
with the input of a logic block (AND 0). The signal of digital input 1 (DI 1) is interconnected to
the second input of the logic block. The logic block output issues the ON/OFF1 command to
switch-on the motor.
Table 1- 9 Parameterizing an interlock
Parameter Description
P0700 = 2 Selecting the command source: Digital inputs
P0701 = 0 Enable ("open") digital input 0 (DI 0) for BICO parameterization
P0702 = 0 Enable ("open") digital input 1 (DI 1) for BICO parameterization
P20161 = 5 The time block is enabled by assigning to runtime group 5 (time slice of
128 ms)
