Using the I/O Chapter 5
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.
When using a ControlLogix or CompactLogix controller, the Logic Command
word is always INT 0 in the output image and the Logic Status word is always:
• INT 0 in the input image when using the drive Add-On Profile.
• INT 2 when using the Generic Profile.
This manual contains the bit definitions for compatible products available at the
time of publication in Logic Command/Status Words: PowerFlex 525 Drives
on
page 157.
Using Reference/Feedback
The Reference is a 16-bit word that is produced by the controller and consumed
by the adapter. The Feedback is a 16-bit word produced by the adapter and
consumed by the controller.
When using a ControlLogix or CompactLogix controller, the Reference is always
INT 1 in the output image (see I/O Image for PowerFlex 525 Drives
on page 64)
and the 16-bit Feedback is always:
• INT 1 in the input image when using the drive Add-On Profile.
• INT 3 when using the Generic Profile.
The Reference and Feedback are 16-bit INT values represent drive speed. The
scaling for the speed Reference and Feedback is 0.01 Hz. For example, a 16-bit
INT Reference value of ‘3000’ would equal a Reference of 30.00 Hz. Note that
the commanded maximum speed can never exceed the value of Host parameter
P044 [Maximum Freq]. PowerFlex 525 Drive Example Speed Reference/
Feedback Scaling on page 65 shows example References and their results for a
PowerFlex 525 drive that has its:
• Host parameter P043 [Minimum Freq] set to 10.00 Hz.
• Host parameter P044 [Maximum Freq] set to 50.00 Hz.

Network Reference Value Speed Commanded Value Output Speed Network Feedback Value
10000 100.00 Hz 50.00 Hz
(1)
(1) The drive runs at 50.00 Hz instead of 100.00 Hz or 65.00 Hz because Host parameter P044 [Maximum Freq] sets 50.00 Hz as the
maximum speed.
