Detail Drive Configuration and Operation
1
Bits 0-15 only of parameter 155 [Logic Status] appear in the Input Image table of the ControlLogix controller.
2
The speed feedback sent from the PowerFlex 700S to the 20-COMM-R is not affected by parameter 73 [Spd Fdbk Scale].
Furthermore, the PowerFlex 700S automatically converts parameter 72 [Scaled Spd Fdbk], which is a floating-point parameter, to
an integer format before the value is transferred to the 20-COMM-R.
When the 20-COMM-R is configured as a ½ rack, the Reference and Feedback
values become words 2 and 3 in the Discrete I/O. The mapping for the Datalinks
sent over block transfer I/O stays the same. Words 0 and 1 in the block transfer I/
O become buffers.
The following example shows the message instructions for the block transfer I/O.
In this example, the 20-COMM-R was setup as a ¼ rack.
