synchronized to the AC line frequency and does not have a speed reference.
The feedback value sent to the 20-COMM-x adapter is the measured AC
line frequency, where a value of 32767 corresponds to 100.00 Hz.
The Converter supports 16-bit data links so if all data links are configured in
the 20-COMM-x then the Connection Parameters in the Logix Processor
must be setup as shown here. This defines twelve 16-bit words sent from the
20-COMM-x to the Logix, and ten 16-bits words sent from the Logix to the
20-COMM-x.
The data is utilized as shown below:
Logix to 20-COMM-x
