Spindle machine diagnosis Q and A :SYNTEC CNC application manual1. tool machine use frequency converter to be spindle control ,command is controlledby analogy voltage that axle card output ,so frequency converter need to setrelated variable ,ex: TelTa frequency converter ,Pr-00 set to d0000 ,Pr-01 setto d0002 ,open the machine after finishing setup , frequency converter displayshould show the revolution opposite this analogy voltage ,if not ,should theparamter setup error2. spindle clockwise and reverse ,control by two relay on relay board ,one isclockwise ,one is reverse ex: TelTa set Pr-38 d0000 ,use FWD ,REV ,DCM contacts ,frequency converter display should show the control status of clockwise andreverse ,if not ,should have error in connecting wire or parameter setup3. emergency stop(switch contact output)go into frequency converter directly ex:台 達 frequency converter E.STOP connect to MI1 ,Pr-39 set to d0007 (NC-contact) ,frequency converter display should show the status of opposite E.STOP , ifnot ,should have error in connecting wire or parameter setup4. parameter setup ,set the frequency converter to the max frequency that system need ,publicform : r.p.m= 120*f/P ex: 4P motor ,60Hz ,R.P.M.=1800r.p.m.,controller setup parameter1671 ,spindle motor gained ,because reaction motor is controlled by slip ,actual speed is lowerthan command speed ,therefore , frequency converter can set to higher revolution5. frequency converter only recieve +10V-0V one way voltage ,when check the wire ,depend onthe spindle speed the screen showed ,use electric meter measure spindle input command value iscorrect or not ,opposite the value ,above frequency converter interface ,should map a frequencyvalue ,if not ,should the error of connecting the wire6. if there is an encoder in spindle ,can set parameter 1711 equal to 1 ,at this time ,screen ofspindle speed shows the actual speed of spindle ,if frequency converter display outputfrequency is steady ,but screen of spindle speed jumped very big(10% above) ,should there is aproblem during encoder installation ,or during connect the wire ,when there is an encoder inspindle ,should set NO. 1651 parameter encoder pulse number each revolution7. when there is an encoder in spindle ,use S 1000 ,the screen should show 1000 revolutionround ,if not ,please check related parameter ,because frequency converter use slip control ,soactual speed a little smaller than set speed ,therefore ,can let paramter 1671 spindle gaineddecrease 5% round ,the actual motor speed will more close to the command value8. tool machine spindle acceleration and deceleration is important ,please set the time 2s (TelTaparameter )113
