With MD21166 = 0, the axis-specific limit value from MD32301 $MA_JOG_MAX_ACCEL iseffective instead of the channel-specific acceleration limitation.NoteWith MD21166 $MC_JOG_ACCEL_GEO [], there is no direct limitation toMD32300 $MA_MAX_AX_ACCEL.NoteWhen a transformation is active, MD32300 $MA_MAX_AX_ACCEL determines the maximumpossible axis-specific acceleration.Maximum jerk when manually traversing geometry axesThe maximum jerk when manually traversing geometry axes in the SOFT acceleration mode(acceleration with jerk limitation) can be specified for each channel via the machine data:MD21168 $MC_JOG_JERK_GEO []With = 0, 1, 2With MD21168 = 0, the axis-specific limit value from MD32436 $MA_JOG_MAX_JERK iseffective instead of the channel-specific jerk limitation.NoteMD21168 $MC_JOG_JERK_GEO acts only when the axis-specific jerk limitation in JOG modehas been enabled for the base machine axes:MD32420 $MA_JOG_AND_POS_JERK_ENABLE [] == TRUEMaximum jerk when manually traversing orientation axesThe maximum jerk when manually traversing orientation axes can be specified for eachchannel via the machine data:MD21158 $MC_JOG_JERK_ORI []For MD21158 to take effect, the channel-specific jerk limitation for the manual traversing oforientation axes must be enabled via the following machine data:MD21159 $MC_JOG_JERK_ORI_ENABLE == TRUENoteOrientation axes are not affected by the machine data MD32301 $MA_JOG_MAX_ACCEL andMD32436 $MA_JOG_MAX_JERK.See alsoManual traversing of geometry axes/orientation axes (Page 183)Manual traversing of the spindle (Page 181)H1: Manual and handwheel travel4.3 Parameter assignment (general)Extended Functions156 Function Manual, 10/2015, 6FC5397-1BP40-5BA3
