2.4 Actions in synchronized actions
Configuration example
MD18860 $MN_MM_MAINTENANCE_MON = TRUE (Activate recording of maintenance
data)
MD33060 $MA_MAINTENANCE_DATA[0]=1 (Config. of the recording of maintenance data)
MD33060 $MA_MAINTENANCE_DATA[1]=1
MD33060 $MA_MAINTENANCE_DATA[2]=1
... Activates the system variables for total travel distance, total travel time and travel count for
the first 3 axes
System variables
The following system variables can be read from the part program and from synchronized
actions:
$AA_TRAVEL_DIST
$AA_TRAVEL_TIME
$AA_TRAVEL_COUNT
$AA_TRAVEL_DIST_HS
$AA_TRAVEL_TIME_HS
$AA_TRAVEL_COUNT_H
S
$AA_JERK_TOT
$AA_JERK_TIME
$AA_JERK_COUNT
Example Distance during part program processing
Repeat read-outs can be used for example to determine the total travel distance of an axis
within an area of a part program.
; Start of processing area in part program
R1 = $AA_TRAVEL_DIST[X]
...
...
R2 = $AA_TRAVEL_DIST[X]
R3 = R2 -R1
