7-10-5 Ladder Program
•
Transfer the created protocol to the Communications Board.
•
The following example describes how to control the Inverter with this protocol.
•
Before using this program in your system, be sure to check the word and data memory allocations and
change them if necessary so that there will be no word or data memory duplication.
•
This program will stop all communications if a communications error or fault occurs. Be sure to set n68
for communications time-over detection selection to 0 through 2 so that the system will stop with time-
over detection.
