1-2 SA500 Power Modules
1.1 Distributed Power System (DPS) Overview
The SA500 is a member of the AutoMax Distributed Power System (DPS) family of
drives. DPS is a programmable microprocessor-based control system that is capable
of real-time control of AC and DC drives. Each Universal Drive Controller (UDC)
module (B/M O-57552) in the AutoMax rack allows the AutoMax Processor to control
up to two drives (20 maximum from one rack). The UDC module communicates over a
fiber-optic link with the PMI located in the SA500 Power Module. The Power Module
can be located up to 750 meters (2500 feet) from the AutoMax rack.
Each DPS drive is controlled by an application task running in the UDC module. All
programming and configuration of the SA500 drive is performed using the AutoMax
Programming Executive software. The SA500 drive requires version 3.4 or later of the
Programming Executive.
