<6>
<1> Only possible for encoder 1 (motor encoder)!
<2> The reference point (setting/shifting) will either be
permanently specified in the unit, or transferred via
an additional channel from the master.
<3> In the event of a fault the fault value will be active in
Gx_XIST2
1 = Encoder sum error
2 = Zero mark monitoring
4 = Terminate reference mark search
5 = Terminate collect reference value
6 = Terminate flying measurement
7 = Terminate collect measured value
8 = Terminate absolute value transmission on
A = Error in reading absolute track of the absolute
value encoder (EnDat-encoder)
<4> The reference value is shifted, for example, via an
analog switch which acts on the position offset of
the respective encoder.
<5> Trigger rough pulse
For referencing with zero pulse only, the rough
pulse (P178) is set to 1 for one cycle in state SD6.
Only possible for encoder 1 (motor encoder)!
<6> Measured value valid must be 1, otherwise a fault
message will be tripped (exception: No fault
message is activated if B70 is missing in states
SD1, SD7 and SD12).
