SYNTEC CNC Application manual - Winter Holztechnik

SYNTEC CNC application manualServo system set the machine probable problem:1. phenomenon:after connecting wire,E.STOP open,find the servo motor still soft,orJOG machine, but machine doesn’t movepossible problem:1. CW,CCW wire does not connect2. OT wire does not connect, driver parameter 41 does not set to 01102. phenomenon:JOG machine,machine start running,but just a moment,return to stop,controller occur follow error too big alarm(or lost position command)possible problem:1. CW,CCW and encoder pulse feeback direction opposite2. the setup is not the same in electronic rate of gear wheel and encoder pulsefeeback3. Kp setup and driver PG2 setup are differentDiagnosis method:1. INC_JOG*1000 run a step,diagnosis screen 40-43 of value increase 1000,ifCW,CCW reverse,and screen 24-27 of value increase negative2. INC_JOG*1000 run a step,diagnosis screen 40-43 of value increase 1000,ifscreen 24-27 of value do not increase 1000,and when move a step more,errorwill accumulate, should be the wrong at rate of gear wheel and encoder setup3. INC_JOG*1000 run a step,diagnosis screen 40-43 of value increase 1000, andscreen 24-27 of value also increase 1000 ,when CON_JOG ,Ferr diagnosis 8-11is not equal to 32-34,should CNC circuit gain does not equal to driver PG2setup3. phenomenon:static status,motor has vibration voicepossible problem:1. VG2 set too big, adjust the value can solve it4. phenomenon:INC JOG*1000, motor has overshot situation, Ferr has positive andnegative exchange situation can be seen by diagnosis screen 8-11possible problem:1. PG2 set too big ,adjust the value can solve it2. VG2 set too smanll5. phenomenon:diagnosis screen 8-11 Ferr in INC JOG*1000 situation ,converge slowlypossible poblem:1. VIC set too big,suggestion:20ms2. PG2,VG2 set too small6. phenomenon:CON JOG diagnosis screen 8-11 Ferr value jump big(ideal jump should104
