The job step of the system is：
（1）, industrial computer motor driver is started by motion control card control, and driven by motor driver controlled motor
Axle moves；
（2）, according to the feedback of optoelectronic switch, motion control card determines the flow of back to zero action；
（3）, if the feedback of optoelectronic switch zero signal, moved to positive direction, until leaving optoelectronic switch zero-bit letter
After number, after moving to optoelectronic switch zero signal to negative direction, continue negative direction motion, found in half-turn pitch position rotary
Decoder internal zero signal, detect that the motion of rotary encoder zero-bit back to zero is completed, do not detect rotary encoder
Zero signal, rotary encoder zero-bit is detected in the range of positive direction half pitch；
（4）If, without photoelectric switching signal feed back, motion module to positive movement after optoelectronic switch is just spacing,
After motion module moves to the signal for detecting optoelectronic switch zero-bit to negative direction, continue negative direction motion, half-turn pitch position
Interior searching rotary encoder internal zero signal, detect that the motion of rotary encoder zero-bit back to zero is completed, do not detect
