6.7.2X8absolutevalueinterfaces
The following absolute value interfaces will be available on encoder channel Ch3
depending on the X8 option being used.

2ndSin/Cosencoder(V2)

See also table in Section "Channel 3: Interface X8 (optional)" on page 74 as well.
They can be selected with P507[0] - ENC_CH3_Sel and P570[0] - ENC_CH3_Abs.
For details, see Section "Main parameters for encoder channel Ch3" on page 78.
6.7.3EnDat(cyclical)X8
Ch3: ENDAT(4) - Cyclical EnDat (2.1 or 2.2)
As the EnDat functionality of the parameters for encoder channel Ch3 is
predominantly identical to that of the parameters for encoder channel Ch1, it is
recommended to read the description for the Ch1 encoder channel parameters (see
Section "EnDat (cyclical)X7" on page 58).
The software versions required to run the EnDat interface are the standard software
versions for the MSD Servo Drive and MSDSingle-Axis Servo Drive Compact.
