Chapter 3 Communication Configuration
PowerFlex 755T 20-COMM-x Network Adapter Compatibility
At initial release, 20-COMM-x adapters cannot be used with PowerFlex 755T
products.
Scaling of Reference and Feedback
The PowerFlex 700S drive parameters for network ‘SpeedReference’ and
‘SpeedFeedback’ data using a 20-COMM-E communication adapter are scaled
for 32767 = 1.0 PU. A Logix value of 32767 written to network DPI Port 5
‘SpeedReference’ 32-bit integer pre-defined output DataLink will equate to a
parameter P40 [Selected Spd Ref ] internal value of 1.0 PU, which is displayed
in RPM where 1.0 PU = P4 [Motor NP RPM].
