7.2 Interface
The following interfaces are available for controlling a technology applicaon:
•
Fieldbus in
terface [0]
•
System bus interface [1]
The
selecon of the interface is performed in »EASY Starter«:
•
Select the Sengs tab, then the Technology applicaon parameter dialog.
When changing the parameter, the inverter must be inhibited.
During a switch-over, both the control words and the status words are switched over. Depend-
ing on the t
echnology applicaon chosen, the bits of the respecve control words and status
words are already pre-assigned.
Assignment of control words and status words:
4Con
trol signals ^ 92
4Status signals ^ 93
The following illustraon shows the basic signal ow within the technology applicaon and
the change-over mechanism of the Interface selecon parameter.
