ABB PU512V2 3BUR001401R1 Robot axis computer board

ABB PM802F/ABB PM803F Features:

High efficiency superscalar RISC CPU
Coprocessor for dedicated system bus and controller redundancy connection communication
ABB PM802F main memory uses static RAM with battery-holding function and starts quickly when the main power supply recovers
ABB PM803F main memory adopts synchronous dynamic Random access memory (SDRAM), which can be quickly started when the main power supply is recovered. It has battery retention function, but the retention time is shorter than ABB PM802F due to its large capacity
The main memory has automatic error checking and modification capability (EDC unit), which can check for 2-bit errors and modify data words with 1-bit errors
Hardware configuration and diagnostic data are stored in 16K EEPROM
The pulse train quickly erases the EPROM for fast ROM operation. This part is mainly used to store the controller curing program, ensuring software upgrade without replacing the EPROM chip
RS232 serial interface for controller diagnostic services and wireless clock signal interface. This interface is a standard 9-pin type D interface on all types of power modules while supporting redundant controller mode operation
Switches for basic operations of the controller are also set on all types of power modules, such as: run/stop work switch, controller reset switch, redundant manual switch
