Using I/O Messaging
Figure 5.5 Example ControlLogix Ladder Logic Program for I/O Messaging (Cont.)
This rung displays the Feedback word from the 1305 drive. Note that the value is in an engineering unit, where "32,767"
equals the Parameter 19 [Maximum Freq] value and "0" equals 0 Hz. The relationship is linear. For example, if Parameter
19 = 60 Hz (default setting), then:
32,767 = 60 Hz
16,384 = 30 Hz
8,192 = 15 Hz
4,096 = 7.5 Hz
0 = 0 Hz (etc.)
