Communication 9.2 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. Table 9- 25 Bit 0 1 2 3 Description of the individual signals in Gn_ZSW Name "Find reference mark" or "Flying measurement " Signal status, description Status: Function 1 - 4 active Valid for "Find reference mark" and "Flying measurement" Bit Meaning 0 Function 1 Reference mark 1 Probe 1 rising edge 1 Function 2 Reference mark 2 Probe 1 falling edge 2 Function 3 Reference mark 3 Probe 2 rising edge 3 Function 4 Reference mark 4 Probe 2 falling edge Note: • Status: Value 1 - 4 available 4 5 6 Bit x = 1 function active Bit x = 0 function inactive Valid for "Find reference mark" and "Flying measurement" Bit Meaning 4 Value 1 Reference mark 1 Probe 1 rising edge 5 Value 2 Probe 1 falling edge 6 Value 3 Probe 2 rising edge 7 Value 4 Probe 2 falling edge 7 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. • 8 9 Probe 1 deflected Probe 2 deflected 10 Reserved 11 Encoder fault acknowledge active 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) 1 Probe deflected (high signal) 0 Probe not deflected (low signal) 1 Encoder fault acknowledge active Note: See under STW.15 (acknowledge encoder error) 0 No acknowledgement active Function Manual 594 Function Manual, 06/2012, 6SL3097-4AB10-0BP4
