Encoder n status word (Gn_ZSW, n = 1, 2)
The encoder status word is used to display states, errors and acknowledgements.
Table 9- 25 Description of the individual signals in Gn_ZSW
Bit Name Signal status, description
Valid for "Find reference mark" and "Flying measurement"
Bit Meaning
0 Function 1 Reference mark 1
Probe 1 rising edge

Note:
• Bit x = 1 function active
Bit x = 0 function inactive
Valid for "Find reference mark" and "Flying measurement"
Bit Meaning

available
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.
