The InterBus host controller board is connected to the InterBus-Periphery bus and
represents an intelligent bus user. It is integrated in the KEB frequency inverter and
permits the fastest data transfer from the InterBus to the frequency inverter. The 15-
pole D-Sub connector CN1 represents the input terminal, via CN2 the next periphery bus
element is connected. If this controller board is the last in the segment, then CN2
remains free. Depending on the bus terminal used up to 8 inverters or other InterBus
modules can be connected per periphery bus. The connecting cables are supplied in
different lenghts complete with connector.
The voltage supply for the host controller board is taken from the corresponding bus
terminal (connection remote bus/periphery bus) via the periphery cable. Thus the
InterBus is ready for communication and operation even if the supply voltage of the
inverter is missing. (In case of missing operating voltage of the host controller board
the InterBus or the bus segment concerned is disconnected.) The bus interface of the
host controller board is isolated from the inverter by optocouplers.

LD1 (green) Operating voltage inverter on. Lights up at switched on inverter and
correct connection to the host controller board.
LD2 (green)
Operating voltage InterBus on. Lights up as soon as the operating
voltage is applied from the bus terminal over the periphery bus cable
and CN1.
LD3 (red) InterBus and host controller board reset. Lights up, when reset is
given by way of the InterBus or when the operating voltage for the
periphery segment is detected as being too low.
LD4 (yellow)
Communication active. Lights up, when communication data is read
or written via the InterBus.
LD5 (red) No connection to the inverter. Lighs up, when no voltage is supplied
to the inverter or when the inverter is still in the initialization phase.
LD6 (yellow) Connection established. Lights up, when the PCP-connection to the
host is established.
LD7 (red)
Communication not synchronized. Lights up briefly after bus starting
or in case of malfunction of layer 2.
