machine tool control system. Although it
illustrates typical connections encountered in most applications, this diagram does not address
every single connection possibility.
The left side of the diagram represents the control, and the right side illustrates the servos,
spindles, I/O connections, etc. Please note that the terminal block labels
TB1
and
TB2
on this
diagram consist of multiple terminal screws which will be discussed in more detail in this
chapter.
