Working Principle
High-speed PCIe x4 bus transmits ultra-precision motion trajectory commands and parameter data from semiconductor industrial PC host to DMC-9940 onboard 64-bit RISC motion processor. The processor executes 31 µs ultra-fast synchronous PID closed-loop control algorithms for 4 independent axes, generates high-frequency differential pulse or 16-bit ±10 V analog servo drive commands output to external high-precision servo amplifiers. 32 MHz differential encoder position feedback signals from micro-positioning stage motors transmit back to card encoder input channels; 32-bit floating-point position registers calculate sub-micron axis position error for continuous high-speed PID correction. Per-axis dual hardware position latch circuits capture encoder position values at nanosecond trigger signal arrival for laser firing and semiconductor wafer alignment registration. Optically isolated high-speed digital DI channels receive micro-limit, home and laser trigger signals to execute instant motion safety interlock logic; isolated DO channels output high-speed actuator trigger signals to field precision equipment. All motion algorithms and tuning parameters are stored in 1 MB onboard flash memory for power-off permanent retention.
