Signal status, description
Valid for find reference marker and measurement on-the-fly.
Bit Meaning
0 Function 1
1 Function 2
2 Function 3
3 Function 4
Note:
Bit x = 1 function active
•
Bit x = 0 function inactive
Valid for find reference marker and measurement on-the-fly.
Bit Meaning
4 Value 1
5 Value 2
6 Value 3
7 Value 4
Note:
Bit x = 1 value available
•
Bit x = 0 value not available
Only one value can be fetched at a time.
•
Reason: There is only one common status word Gn_XIST2 to read the values.
The probe must be configured to a "high-speed input" DI/DO on the Control
•
Unit.
1 Probe deflected (high signal)
0 Probe not deflected (low signal)
1 Probe deflected (high signal)
0 Probe not deflected (low signal)
-
1 Encoder fault acknowledge active
Note:
See under CTW.15 (acknowledge encoder error)
0 No acknowledgement active
-
1 Acknowledgement for Gn_STW.13 (request cyclic absolute value)
Note:
Cyclic transmission of the absolute value can be interrupted by a
function with higher priority.
