<2>
The contents of position actual value 2 (Gn_XIST2) at [4704] depends on Gn_STW and Gn_ZSW.
This can be done as follows:
– Undefined for a parking encoder (Gn_ZSW.14 = 1).
– For Gn_ZSW.15 = 1 the fault code for encoder faults is located here.
– Position actual value at the reference mark (for Gn_STW.7 = 0 and Gn_ZSW.4...7 > 0; with handshake).
– Position actual value due to flying measurement (for Gn_STW.7 = 1 and Gn_ZSW.4.7 > 0; with handshake).
– Cyclic absolute position value (free-running value, e.g. from the EQN absolute track (for Gn_ZSW.13 = 1).
