主题:每日一贴之攻丝螺纹不正确 此问题出现在主轴有档位的情况,当主轴换档后,各进给轴的传动比使用的是与主轴档位相应的参数集设置。因此,需要设置MD31050和MD31060的[1]、[2]系统有6个位置控制伺服参数集,用于机床运行过程中,位置控制随着机床特性的改变进行快速地匹配,如主轴的换轴之间的动态匹配,如攻丝 下列数据跟参数集相关: Denominator load gearbox MD 31050: DRIVE_AX_RATIO_DENOM [n] Numerator load gearbox MD 31060: DRIVE_AX_RATIO_NUMERA [n] Servo gain factor MD 32200: POSCTRL_GAIN [n] Backlash compensation (SW 5 and higher)MD 32452: BACKLASH_FACTOR[n]
Feedforward control factor (SW 5 and higher) MD 32610: VELO_FFW_WEIGHT[n] Exact stop limits (SW 5 and higher) MD 36012: STOP_LIMIT_FACTOR[n] MD 36000: STOP_LIMIT_COARSE MD 36010: STOP_LIMIT_FINE and zero speed window MD 36030: STANDSTILL_POS_TOL Equivalent time constant MD 32800: EQUIV_CURRCTRL_TIME[n] Current control loop for torque feedforward control Equivalent time constant MD 32810: EQUIV_SPEEDCTRL_TIME[n] Speed control loop for speed feedforward control Time constant of MD 32910: DYN_MATCH_TIME[n] dynamic response adaptation Threshold value for MD 36200: AX_VELO_LIMIT[n] velocity monitoring
