Using Logic Command/
Status The Logic Command is a 16-bit word of control data produced by the
controller and consumed by the adapter. The Logic Status is a 16-bit word
of status data produced by the adapter and consumed by the controller.
PowerFlex 750-Series drives have a 32-bit Logic Command/Status—but
when using a 20-COMM-C or 20-COMM-Q adapter only the first 16 bits
can be used.
This manual contains the bit definitions for most compatible products
available at the time of publication in
Appendix D , Logic Command/Status
Words . For other products, see their documentation.
Using Reference/Feedback The Reference is produced by the controller and consumed by the adapter.
The Feedback is produced by the adapter and consumed by the controller.
The size of the Reference/Feedback is determined by the drive and can be
displayed with adapter Parameter 07 - [Ref/Fdbk Size].
