Communication
10.1 Communication according to PROFIdrive
Encoder n status word (Gn_ZSW, n = 1, 2)
The encoder status word is used to display states, errors and acknowledgements.

Signal status, description
Valid for "Find reference mark" and "Flying measurement"
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 mark" and "Flying measurement"
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" of the Control Unit.
•
1 Probe deflected (high signal)
0 Probe not deflected (low signal)
