Power Distribution
Once you have planned your system layout, you can begin connecting
power and components to your system. In this section we discuss:
how ac power is distributed through the system
connecting the main power supply and operator interface power supply
main and operator panel power supply input power specifications
protective grounding
The external ac power connections to the control and operator panel are
covered in this section. For information on external ac power source
connections to servo amplifiers, servo motors, and I/O modules, refer to
the sections that cover these components. For details on external ac power
source connections to an analog servo amplifier or analog servo motor,
refer to the documentation provided by the manufacturer.
Figure 3B.1 shows the power distribution from the supply to the control
and its components.
