3.8 Approaching a fixed point in JOG
Extended Functions
188 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
– MD32431 $MA_MAX_AX_JERK [0] (maximum axial jerk for path motions in the
dynamic response mode DYNNORM)
Note
MD32431 $MA_MAX_AX_JERK is only effective when the axial jerk limitation for
single-axis movements has been enabled for the machine axes to be traversed:
MD32420 $MA_JOG_AND_POS_JERK_ENABLE [<axis>] == TRUE

3.8.4 Programming
System variables
The following system variables that can be read in the part program and in the synchronous
actions for the "Approach fixed point" function.
System variable Description
$AA_FIX_POINT_SELECTED [<Axis>] Number of fixed point to be approached
$AA_FIX_POINT_ACT [<Axis>] Number of the fixed point on which the axis is
currently located
3.8.5 Supplementary Conditions
Axis is indexing axis
The axis is not traversed and an alarm is output if the axis to be traversed is an indexing axis
and the fixed point position to be approached does not match an indexing position.
Frames active
All active frames are ignored. Traversing is performed in the machine coordinate system.
