Binectors and connectors
Connectors and binectors are used to exchange signals between the individual blocks:
● Connectors are used to interconnect "analog" signals. (e.g. MOP output speed)
● Binectors are used to interconnect "digital" signals. (e.g. 'Enable MOP up' command)
Binector/connector outputs (CO/BO) are parameters that combine more than one binector
output in a single word (e.g. r0052 CO/BO: status word 1). Each bit in the word represents a
digital (binary) signal. This summary reduces the number of parameters and simplifies
parameter assignment.
Binector or connector outputs (CO, BO or CO/BO) can be used more than once.
When must you interconnect signals in the converter?
If you change the signal interconnection in the converter, you can adapt the converter to a
wide range of requirements. This does not necessarily have to involve highly complex
functions.
Example 1: Assign a different function to a digital input.
Example 2: Switch the speed setpoint from the fixed speed to the analog input.
How much care is required when you change the signal interconnection?
Always take care when establishing internal signal interconnections. Note which changes
you make as you go along since the process of analyzing them later can be quite difficult.
The STARTER commissioning tool offers signals in plain text and simplifies their
interconnection.
Where can you find additional information?

● The parameter list in the List Manual is sufficient for more complex signal
● You can also refer to the function diagrams in the List Manual for complex signal
