DESCRIPTION
Part number: A20B-3900-0052
Description: 16/18/21iA SRAM MODULE 512KB
Product Series: A20B-3900
The FANUC Series 16i, 160i, 18i, 180i, 21i, and 210i are super–compact ultra–thin CNC models with built–in liquid crystal displays. Each CNC unit is a mere 60 mm deep and features, immediately behind the liquid crystal display, a small CNC printed circuit board developed by utilizing state–of–the–art LSI and surface–mount technologies. Super–compact ultra–thin open CNC models are also available. The CNC printed circuit board incorporates PC functions that are fully compatible with the IBM PC.
The amount of cabling in the electrical unit of the machine can be significantly reduced by using a high–speed serial servo bus, which connects the CNC control unit and multiple servo amplifiers by a single optical fiber cable. Another innovation which simplifies the electrical unit of the machine tool is the use of compact distributed I/O modules, which can be separately mounted on the machine operator’s panel and control panel.
The number of all controlled axes is the sum of the number of machine controlled axes and the number of loader controlled axes. The machine controlled axes include Cs axis.
