Diagnosis function and enforced dynamizing

The two stop paths are monitored by the frequency inverter every 32 ms. If at least one of the two
inputs S1IND (STOA) or S7IND (STOB) is switched off, the pulse block is activated. Additionally, a 5-
second monitoring cycle begins for the other stop path. If this path is not stop within 5 s, error F1205
is output.
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 nega-
tive, the frequency inverter cannot be switched on anymore, and error F1201 is signaled. Starting is
possible again only after the error has been repaired and the next diagnosis cycle has been completed
successfully.
