5.5.2 Online diagnostics
Encoders with purely digital serial interfaces (e.g. EnDat 21 and 22, Fanuc, Mitsubishi) do not
provide incremental signals. Therefore, the encoders cyclically output the valuation numbers
in order that the encoder functions can be evaluated. The ATS software displays these as bar
diagrams. The valuation numbers provide the current state of the encoder and ascertain the
encoder’s “function reserves.”
The scaling is the same for all HEIDENHAIN encoders; it is indicated as function reserve
(0 – 100 %).
The valuation numbers supported by the respective encoder (number of displayed bars) are
saved in the encoder memory (with EnDat encoders: visible in "Manufacturer parameters
EnDat2.2/Diagnostic status").
The following screenshots show the online diagnostics of an EnDat interface.
8 Double-click "Online diagnostics" to open the window "Online diagnostics/Diagnostic mode".
Note
Display and functions may vary depending on the product key and the connected encoder!
If the "Online diagnostics" is not displayed in the ATS menu, the encoder interface does not
support this function.
