Optimization strategyDifferent optimization strategies are used, depending on the operating range of the spindle:● A robust setting is selected for speed controller and position controller for the spindleoperation and tapping. The optimization aggressiveness is reduced for the spindle and theservo gain factor is limited to 3 [1000/min].● In addition to the speed control mode, the position control mode is also optimized, e.g. forSPOS: Servo gain factor maximum 3 [1000/min].● The same optimization strategy that was selected for the path axes is selected for the axismode. If only one drive data set (DDS) is defined, this strategy will also be used for the othermodes. If the speed controller adaptation is also enabled in the drive, the speed controllergain and the integral time are attenuated at higher speeds.● For tapping, the spindle mode with gear stages and position control is used. The pathcalibration with the relevant path axis is needed for tapping. Ensure that all gear stages usedduring tapping are calibrated both in the spindle and along the path axis.Optimization resultThe optimized parameters are displayed in the "Controller data overview" dialog:During tapping, the same values are set in the following machine data for the spindle and allfurther axes:MD32200 $MA_POSCTRL_GAIN Servo gain factorMD32800 $MA_EQUIV_CURRCTRL_TIME Equivalent time constant current control loop for feed‐forward control [s]MD32810 $MA_EQUIV_SPEEDCTRL_TIME Equivalent time constant speed control loop for feedfor‐ward control [s]MD32900 $MA_DYN_MATCH_ENABLE Dynamic response adaptationDrive tuning10.4 Spindle optimization (automatic)CNC Commissioning: NC, PLC, Drive314 Commissioning Manual, 12/2019, A5E48312804B AA
