Siemens SINUMERIK 828D

Special Motion Commands
4.8 Extended measuring function (MEASA, MEAWA, MEAC) (option)
Job planning
264 Programming Manual, 07/2010, 6FC5398-2BP40-0BA0
Note
MEASA and MEAWA are non-modal; they can be programmed together in one block. However, if
MEASA/MEAWA is programmed together with MEAS/MEAW in the same block, an error message is
output.
Significance
Command: Axial measurement with deletion of distance-to-go
MEASA
Effective: non-modal
Command: Axial measurement without deletion of distance-to-go
MEAWA
Effective: non-modal
Command: Continuous axial measurement without deletion of
distance-to-go
MEAC
Effective: non-modal
<axis>
Name of channel axis used for measurement
Two-digit number indicating the operating mode (measuring
mode and measuring system)
Measuring mode(units decade):
0 Cancel measuring task.
1 Up to 4 different trigger events can be activated
simultaneously.
2 Up to 4 trigger events can be activated consecutively.
