11.1.4 InterBus Loop-
Operator
The InterBus loop-operator is incorporated in a slip-on housing and is connected to a
IB-loop stub. InterBus (IB) and loop are specifications of the company Phoenix Contact,
Blomberg. The voltage supply is done over the loop from the series-connected loop-
bus terminal via a 2-wire, twisted cable together with the modulated data signals. The
isolation to the inverter is realized with optocouplers. The switching off of the inverter
has no effect on the IBS cycle.
After switching on the loop-operating voltage the inverter is adjusted to the fastest
possible transmission rate via the internal, serial KEB-DIN66019 protocol. For that
the application password (UD01=440) as well as the baud rate (UD07) and the inverter
address (UD06=1) are automatically adjusted.
Picture11.1.2
InterBus Loop-Operator
The connection of the operator to the loop is done by means of twisted, unshielded
loop-cables (Phoenix Contact) according to following scheme:
terminal 1
Loop In +
terminal 2
Loop In -
terminal 3
Loop Out +
terminal 4
Loop Out -
The last user is again connected with the loop-in interface of the bus terminal (Phoenix
Contact). Of course, other loop-users like digital I/O modules etc. can be connected,
too. In each case the polarity as well as the data direction IN / OUT must be observed.
