Product description
The Fanuc A87L-0001-0084 is a bubble memory unit for legacy CNC controls in which programs and machine data are stored in non-volatile memory. Within the A87L-0001 family, the complete identification number denotes a 320 m bubble-memory board with a storage capacity of 128 KB. The board is associated with Fanuc System 6 and System 11 and is installed within the control as a separate memory assembly. Magnetic bubble memory retains data without an applied supply voltage and therefore differs functionally from volatile working memory. Adjacent variants in the same family have different capacities: A87L-0001-0085 represents 640 m and 256 KB, while A87L-0001-0086 represents 1280 m and 512 KB. The replacement table also lists assembly A16B-2201-0132 for the memory size of the A87L-0001-0084. Programs, parameters, tool offsets and other control-specific contents belong to the memory set of the respective machine and are not part of an empty replacement assembly. Slot, control family, software version and existing BMU variant therefore define the relevant configuration attributes. The A87L-0001-0084 is built as a plug-in printed circuit board and is clearly distinguished from other A87L versions by its complete Fanuc identification number. This defines it as a specific memory component for maintenance and spare-parts stocking of legacy Fanuc CNC systems. Dimensions and weight support mechanical and logistical classification; the part number present on the board remains decisive for identity.
