5-8 Using the I/O
The Drive I/O Control program ( Figure 5.4 ) defines the I/O needed to
control the drive.
PLC-5 Example
Figure 5.4 PLC-5 Ladder Logic Example for Drive I/O Control
In this example, an operator station is wired into the local PLC-5/40C rack as follows:
O:000/0 Drive Ready
O:000/1 Drive Active
O:000/2 Drive Forward
O:000/3 Drive Reverse
O:000/4 Drive Faulted
O:000/5 Drive At Speed
O:001 Operator Speed Feedback
I:000/0 Stop (Normally
I:000/1 Start (Normally Open Pushbutton) Open Pushbutton)
I:000/2 Jog (Normally Open Pushbutton)
I:000/3 Clear Faults (Normally Open Pushbutton)
I:000/4 Forward / Reverse Selector Switch
I:001 Operator Speed Reference
In this example, a PowerFlex 40 drive with installed 22-COMM-C ControlNet adapter is mapped as follows:
N9:0 Logic Status N10:0 Logic Command
N9:1 Speed Feedback N10:1 Speed Reference
Rungs 0000 through 0005 move the Logic Status from the drive to the operator station.
