Figure 9-8 Example of encoder interface (encoder-1: two actual values, encoder -2: one actual
value)
Encoder n control word (Gn_STW, n = 1, 2)
The encoder control word controls the encoder functions.
Table 9- 24 Description of the individual signals in Gn_STW
Bit Name Signal status, description
If bit 7 = 0, then find reference mark request applies:
Bit Meaning
0 Function 1 Reference mark 1
1 Function 2 Reference mark 2
2 Function 3 Reference mark 3
3 Function 4 Reference mark 4
If bit 7 = 1, then find flying measurement request applies:
0 Function 1 Probe 1 rising edge
1 Function 2 Probe 2 falling edge
2 Function 3 Probe 3 rising edge
3 Function 4 Probe 4 falling edge
Note:
• Bit x = 1
Bit x = 0

Functions
• The following applies if more than 1 function is activated:
The values for all functions cannot be read until each activated function
has terminated and this has been confirmed in the corresponding status
bit (ZSW.0/.1/.2/.3 "0" signal again).
• Find reference mark
It is possible to search for a reference mark.
• Equivalent zero mark
• Flying measurement
Positive and negative edge can be activated simultaneously.
