6.5.1.3 Extend telegrams and change signal interconnection
When you have selected a telegram, the inverter interconnects the corresponding signals
with the fieldbus interface. Generally, these interconnections are protected so that they
cannot be changed. With the appropriate inverter settings, these interconnections can be
changed.
Extending a telegram
Every telegram can be extended by "attaching" additional signals.
