Table 10-19 Description of the individual signals in Gn_STW

Bit	Name		Signal status, description
0	Find	Status:	Valid for find reference marker and measurement on-the-fly.
1	reference	Function 1 - 4	Bit	Meaning
2	mark or flying	active
			0	Function 1	Reference marker 1
	measurement
3					Probe 1 rising edge
			1	Function 2	Reference marker 2
					Probe 1 falling edge
			2	Function 3	Reference marker 3
					Probe 2 rising edge
			3	Function 4	Reference marker 4
					Probe 2 falling edge
			Note:
			• Bit x = 1 function active
			Bit x = 0 function inactive
4		Status:	Valid for find reference marker and measurement on-the-fly.
5		Value 1 - 4	Bit	Meaning
6		available
			4	Value 1	Reference marker 1
7					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
			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.

8		Probe 1	1	Probe deflected (high signal)
		deflected
			0	Probe not deflected (low signal)
9	Probe 2 deflected		1	Probe deflected (high signal)
			0	Probe not deflected (low signal)
10	Reserved		-
11	Encoder fault acknowledge		1	Encoder fault acknowledge active
	active			Note:
				See under CTW.15 (acknowledge encoder error)
			0	No acknowledgement active
12	Reserved		-
13	Transmit cyclic absolute value		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.
				•	See Fig. 1-9
				•	See Gn_XACT2
			0	No acknowledgement
14	Parking encoder		1	Parking encoder active (i.e. parking encoder switched off)
