Industrial 57652-A Drive Controller Module Extended Memory

Reliance Electric AutoMax Universal Drive Controller Module Ext. Mem. 57652-A is a rack‑mounted drive controller that provides universal drive control for one or two AC and/or DC drives within an AutoMax backplane. It uses extended memory (EM) and non‑volatile flash memory to store UDC tasks, drive configuration information, and operating system data for both the UDC and Power Module Interfaces, enabling reliable startup and operation across power cycles. The module features dual‑port memory accessible by both the AutoMax processor and the UDC microprocessor, allowing coordinated data exchange and faster recovery after resets. In a typical AutoMax rack, up to 10 UDC modules can share a single backplane, enabling control of up to twenty drives across the rack. Applications include industrial automation tasks such as conveyors, pumps, and machine tools where centralized, flexible drive control is required and precise coordination between multiple drives is essential.
