Mitsubish manual servo parameter setup(J2 ,J2 super):SYNTEC CNC application manualPcmd(Pulse)M_ENC*CDV(4)CMX(3)+-PG(J2 35J2S 06)VG2(37)VIC(38)1/SrevDriver(sec-1)Speed circuitoutput(Pulse)*ENR(27)(rev)Position circuitServo system block chartDriver chartManual set machine parameter description:PG1:position circuit gain real setup value(J2 parameter 35,J2 super:parameter 06)VG2:speed circuit gain real setup value (parameter 37)VIC:speed integral circuit real setup value(parameter 38)Manual parameter setup description:Step 1、parameter change to manual servo parameter adjust:1. driver parameter 19 change to ABCD(origin is 0001)2. parameter 2 change to(J2:0202 ,super:0308),cancel AUTO TUNNING3. shutdown and reset4. adjust PG1,VG2,VICstep 2、position circuit gain adjust(J2 adjust PG2(35),J2 super adjust PG1(06) ):1. first set the needed servo circuit gain Kp in CNC system,CNC parameter 181(CNCtool machine,encoder Kp set to 30,optical ruler set to 20)2. adjust servo parameter PG1,let Ferr jump theory value equal to real value (CNCdiagnosis screen parameter 8,9,10 equal to 32,33,34,35)step 3、VG2 adjustion(speed circuit rigidity):1. VG2 is the adjustion of speed circuit rigidity,VG2 bigger ,rigidity stronger,reacha value ,the machine will vibrate, decrease this value 10-20%2. use 1m/min speed,Ferr jump small at 20μm(the smaller is better)3. CNC tool machine in usual,direct connect situation VG2=PG1*(10~40)Step 4、VIC adjust(integral constant):1. VIC speed circuit integral machine suggest set to 20ms ,the machine bigger thesteady stay error is bigger ,servo response become lowerP.S.1. J2 super NO.3 parameter CMX,setting value is J2 4 times(by 4)2. parameter NO.4 CDV setting value is J2 1/2 times(divide 2)102
