SYNTEC CNC Application manual - Winter Holztechnik

SYNTEC CNC application manual• set the two value very close in the axle that move together ,or the process circle may not be acircle• Ferr check in motion ,it is important protect to machine ,when screen occur alarm messageof following error too big ,please go to the diagnosis procedure aboveLattice value setupphenomenon : continue Homing many times ,occur origin position err a revolutionof motor sometimes(ex: 4mm)reason : because the motion position of origin limit switch ,is close to theencoder INDEX position ,cause when find Home limit switch may before orafter INDEX ,so ,position of Home will err a revolution of motor .noun explain :limit shift distance : the distance from find Home limit switch ,to find INDEX ,thisvalue can read from diagnosis screen56(X) ,57(Y) ,58(Z) ,59(A) ,60(spindle) ,this value shows thepercentage ,normal is 20-80%lattice value : parameter can set the Min limit shift distance is 50% of pitch ,whenfind HOME ,if CNC find limit shift distance is smaller than this setvalue ,will find next INDEX ,use next INDEX to be origin of thisaxle ,parameter 941(X),942(Y),943(Z),944(A) ,in convenient CNCapplication person ,only set if start lattice protection or not ,CNC willset lattice value protection value automaticallyresult way :1. when test the machine ,set limit switch ,find Home2. enter into diagnosis screen ,see parameter 56(X),57(Y),58(Z) ,59 if this valueis too big or too small ,show distance of LIMIT and INDEX too close ,suggesttion :the position 20% to 80% of motor3. the principles of set the lattice value protection : let origin INDEX axle hasa safty distance to limit switch(1/5 revolution above) ,if the original limitshift value is 1/5-4/5 revolution of encoder ,do not start lattice valueprotection ,if shift value smaller than 1/5 or bigger than 4/5 revolution ,thenstart lattice value protection(contorller set 50% of ball screw automatically)4. after set the parameter ,do Homing again ,see if limit shift value bigger than1/2 revolution in every times ,if it did ,show that ignore INDEX near limitswitch ,this lattice value protection become effective5. if the quality of limit switch is too bad ,limit shift is too big when eachtime Homing ,can set the speed small in find HOME second step(parameter 841-860) ,it will rise the reapper of finding limit shift value ,help the setup of latticevalue protection110
