6.6 Diagnosis function and enforced dynamizing

The test required for monitoring the stop paths is performed by the frequency inverter automatically.
Via automated enforced dynamizing, the stop paths are checked for errors. If the test result is negative,
the frequency inverter cannot be switched on anymore, and an error of the group "F12" (in example
F1201) is signaled. Starting is possible again only after the frequency inverter was completely discon-
nected from voltage supplies and error has been corrected.
