Testing Functional Safety
Safety-relevant functions of HEIDENHAIN position encoders with the purely serial EnDat 2.2
interface with option "safety-related applications" (Functional Safety) are tested with the ATS
software function "Functional safety encoder check" (belongs to the Diagnostics function group).
Encoders of this type are distinguished by the word "Safety" printed on the ID label.
Note
The Functional safety encoder check features an "Assistant" (wizard) function.
This wizard must run all tests without any error! If there is any error in the "Safety" tests,
the defective position encoder has to be replaced!
Attention
After installation and exchange of "Functional Safety" components, an acceptance test
according to the machine instructions must be performed.
