Generic profile technical data
Overview
The generic profile aims to fulfill the industry-standard drive profile for each protocol 
(e.g. PROFIdrive for PROFIBUS, AC/DC Drive for DeviceNet).
Control Word
As described earlier in Control interface the 
CONTROL WORD is the principal means 
for controlling the drive from a fieldbus system. For specific 
CONTROL WORD content, 
see the user’s manual provided with the FBA module.
Status Word
As described earlier in Control interface, the contents of the 
STATUS WORD is status 
information, sent by the drive to the master station. For specific 
STATUS WORD 
content, see the user’s manual provided with the FBA module.
Reference
As described earlier in Control interface, the 
REFERENCE word is a speed or 
frequency reference.
Note: REF2 is not supported by the Generic Drive profiles.
Reference scaling
REFERENCE scaling is fieldbus type specific. However, at the drive, the meaning of a 
100% 
REFERENCE value is fixed as described in the table below. For a detailed 
description on the range and scaling of the 
REFERENCE, see the user’s manual 
supplied with the FBA module.
