1. Kusistimu yokulawula ye-PLC yomshini wokusaha we-CNC, isignali yesenzo esivame ukuvuleka noma evamise ukuvaleka yethulwa endaweni yokufaka yesignali ye-PLC, futhi ukuqala nokuma kwenjini yomshini wokusaha kulawulwa uhlelo.

2. Ukusebenzisa izinga lokushisa ukuze kuvikelwe injini yomshini wokusaha, usebenzisa amadivaysi ashisayo noma ukumelana nokushisa, ikona lika-thermoelectric likala izinga lokushisa lemoto futhi linikeza isignali yokushisa ngokweqile ngesilawuli sokushisa ukuze kuvikelwe injini.

3. Sebenzisa i-thermal relay ukuze ulinganise ukuthi i-current iyalidlula yini inani lamanje elilinganiselwe le-CNC band saw motor. Lapho ukulayisha ngokweqile kufinyelelwa, misa injini bese unikeza isignali ye-alamu ukuze uvikele i-band saw motor.

4. Ngokusho kobukhulu bamandla emoto yomshini wokusaha we-CNC, khetha i-transformer yamanje efanelekile, uyifake ebhokisini lokulawula likagesi, bese wethula isignali yesenzo ku-loop yokulawula. Uma kunokungalingani kwezigaba ezintathu noma umsinga omkhulu, i-relay eshisayo izosebenza, futhi iluphu yokulawula izonqamula ukunikezwa kwamandla.
