System Grounding

Figure 5A.49 and Figure 5A.50 illustrate the recommended 9/440
resolver–based grounding scheme. All grounds terminate on a single
point. Note there are two separate ground wires going to the system
module. One ground connects to PE of the system module power terminal
block, the other connects to the ground stud found just beneath the wiring
board on the mounting bracket for the 9/440 Resolver–based CNC
assembly.
