UGRMEM-01SNQ12 is an original Yaskawa dedicated memory expansion PCB, specially designed for Motoman XRC robot controllers and YASNAC CNC control systems. It provides data cache and permanent storage space for system operating programs, mechanical origin parameters, servo setting data, user editing programs and fault history information of robot and numerical control equipment. The board is installed via plug-in gold finger structure on the main backplane slot inside control cabinet, matching perfectly with previously listed cabinet accessories including SZRCR-NTU02 power supply unit and SL series terminal bases. This memory board is widely used for maintenance replacement of arc welding, handling robots and Miyano TSV series CNC machining centers. Original mass production has been terminated; available stock mainly consists of pre-tested used and refurbished spare components for aftermarket equipment repair.
