You cannot change the signal interconnection within the block. However, the interconnection
between blocks can be changed by interconnecting the inputs of a block with the appropriate
outputs of another block.
The signal interconnection of the blocks is realized, contrary to electric circuitry, not using
cables, but in the software.

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)

Symbols for binector and connector inputs and outputs
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.
Interconnecting signals
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.
