(YES): The IGBTs are tested on pow er up and every time a run command is sent. These tests cause a slight delay (a
few ms). In the event of a detected fault, the drive w ill lock. The follow ing faults can be detected:
-
Drive output short-circuit (terminals U-V-W): SCF display.
-
IGBT inoperable: xtF, w here x indicates the number of the IGBT concerned.
-
IGBT short-circuited: x2F, where x indicates the number of the IGBT concerned.

(1) Because, in this case, the detected fault does not trigger a stop, it is recommended to assign a relay or logic output to
its indication.
These parameters only appear if the corresponding function has been selected in another menu. When the parameters can
also be accessed and adjusted from w ithin the configuration menu for the corresponding function, their description is detailed
in these menus, on the pages indicated, to aid programming.
