Fanuc A02B-0259-C221#A Operator Panel. This hand held controller allows functional control over axes and spindle in a different location to the main machine tool operator station. The CNC handwheel in pendant form runs with 16i/18i control systems, though ours runs with a 16i-MB controller. This unit interfaces back to the CNC via the I/O interface on the operator. This unit is twinned with the A02B0259C220 interface unit.
