ABB ACS560 - About the Control Profiles

446 Fieldbus control through the embedded fieldbus interface (EFB)
About the control profiles
A control profile defines the rules for data transfer between the drive and the fieldbus
master, for example:
• if packed boolean words are converted and how
• if signal values are scaled and how
• how drive register addresses are mapped for the fieldbus master.
You can configure the drive to receive and send messages according to one of the
two profiles:
• ABB Drives
• DCU Profile.
For the ABB Drives profile, the embedded fieldbus interface of the drive converts the
fieldbus data to and from the native data used in the drive. The DCU Profile involves
no data conversion or scaling. The figure below illustrates the effect of the profile
selection.
