Yadda GE Fanuc ke Kawar da Kwaɗayin “Sauri ko Daidaito”
Yawancin tsarin sarrafawa suna tilasta ka zaɓa tsakanin zagaye masu sauri da kuma daidaito mai matuƙar tsauri. GE Fanuc tana cire wannan kwaɗayin. Hardware-synchronous bus ɗinta yana haɗa “logic” da “motion” a cikin lokaci guda ɗaya. Tsarin yana daidaita lankwacen hanzari (acceleration curves) ta atomatik bisa ga ainihin bayanan nauyi da aka auna. Saboda haka, kana ci gaba da samun sauri mai yawa ba tare da rasa daidaito ba.
Daidaidawar Rhythm a Rufe (Closed-Loop): Wuce Tsarin Daidaita Layi da Hannu
Daidaitawa da hannu tana kasa aiki bayan kayan aiki sun fara sawa ko yanayin zafi ya canza. GE Fanuc tana amfani da closed-loop rhythm adaptation maimakon haka. Tsarin yana sa ido kan kowane zagayen tashoshi a ainihin lokaci.
