Fieldbus adapter
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 section Control interface on page 252, 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 section Control interface on page 252, 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 section Control interface on page 252, 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.
Actual Values
As described earlier in section Control interface on page 252, Actual Values are
words containing drive values.
