Rockwell Automation 22-COMM-P PowerFlex Profibus Adapter - Manual (Page 53)

Using I/O Messaging 5-3
The Logic Command is a 16-bit word of control produced by the
controller and consumed by the adapter. The Logic Status is a 16-bit
word of status produced by the adapter and consumed by the controller.
When enabled, the Logic Command/Status word is always word 0 in the
I/O image.
This manual contains the bit definitions for compatible products
available at the time of publication in
Chapter C , PowerFlex 4-Class
Drives Logic Command/Status Words . For other products, refer to their
documentation.
The Reference (16 bits) is produced by the controller and consumed by
the adapter. The Feedback (16 bits) is produced by the adapter and
consumed by the controller. When enabled, Reference/Feedback begins
at word 1 in the I/O image.

Using Reference/Feedback
Size Drive Valid Values (1)
(1) The Reference/Feedback for a PowerFlex 4-Class drive is set in Hz and not in engineering units like
PowerFlex 7-Class drives. For example, “300” equates to 30.0 Hz (the decimal point is always
implied) for all PowerFlex 4-Class drives except PowerFlex 400 for which “3000” equates to 30.00
Hz. In all cases, a minus value equates to reverse motor direction, and a plus value equates to
forward motor direction.
