Testing DRIVE-CLiQ Functional Safety
The testing wizard "Functional Safety encoder check" is also available to examine not functionally
safe DRIVE-CLiQ (DQ) encoders, as the interface side expects certain information and behavior
also of encoders without Functional Safety.
Encoders that have contributed to the failure of a safety function in the application must be
returned to HEIDENHAIN Traunreut. Encoders may be repaired exclusively by trained
HEIDENHAIN technicians.
Encoders of this type are distinguished by the word "Safety" printed on the ID label.
8 Double-click "Functional Safety encoder check" to start the wizard.
List of diagnostic functions:
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.
