3.1 Outline3-23.1 OutlineThe Position Correction Table is used to drive the Servomotors while correcting the positionbased on the correction amounts set in the table in order to minimize wasted torque producedby mechanical differences in the machine.Using this function can reduce cycle time because it can drive the Servomotors without pro-ducing wasted torque between two axes.The SERVOPACK adds the correction amount to the reference position from the host control-ler, and then it moves the slave axis.For this reason, the coordinate position of the slave axis is offset from the reference positionfrom the host controller by only the added correction amount.Master axis Slave axisPm1Pm2Pm3Pm4Pm5Ps1Ps2Ps3Ps4Ps5Master axis Slave axisTorqueTorqueSpeedTimeMaster axis00Slave axisTimeTorqueTimeTorqueSpeedTimeTension is produced between the axes when theServomotors are driven due to mechanicaldifferences, and this produces wasted torque.Wasted torque produced due to mechanical differencescan be minimized by driving the Servomotors whilecorrecting the position of the slave axis based on thecorrection amounts set in the table.Wasted torque isnot producedbetween themaster and slaveaxes.This muchwastedtorque isproduced.InformationMaster axis Slave axisReference positionfrom host controllerCorrection amount
