II. Core Functions

HMK-3993 is the standard operation keyboard and interface board of Yaskawa's old CNC system. Its main functions are:

Machine tool operation input: numeric keys, function keys, axis movement, program editing, start / stop, mode selection

HMI interface: connects the system host and the operation panel, transmits key signals

Status feedback: LED indicator lights display system operation, alarms, axis status

Signal processing: key debounce, level conversion, photoelectric isolation

Plug-and-play: supports online replacement, compatible with J50M and other old systems
