Rockwell Automation SA3100 AutoMax Distributed Power System - Manual (Page 30)

2-10 AutoMax Distributed Power System Overview
The faceplate contains transmit and receive ports for one channel of fiber-optic cable
and 15 LEDs to indicate the status of the PMI and inverter circuitry, the feedback
device, the drive I/O, and the communication link to the UDC module. The resolver
feedback connector is shared by the resolver interface and the analog input in the
same manner as on the Resolver & Drive I/O module in the PMI rack. The faceplate
also provides a connector for drive I/O. Two rail ports on the module’s faceplate
provide connection to AutoMate digital and analog rails.
2.4.2 SA3000 Medium Power Drives (70-240 Amp)
The hardware components of a SA3000 Medium Power drive are the four-slot PMI
rack and the Medium Power SA3000 AC Power Modules. These are shown in
figure 1.3 and are described in detail in the following sections.
2.4.2.1 SA3000 Four-Slot PMI Rack and Modules
The same four-slot PMI rack is used for Medium Power SA3000 drives that is used for
SD3000/SF3000 DC drives. The first three slots contain the same Power Supply
module, PMI Processor module, and Resolver & Drive I/O module found in the DC
PMI rack. For AC drive control, however, the rightmost slot contains an AC Power
Technology module. Refer to figure 2.5.
