Siemens / F30851
Series: DCM-6RA80
Power unit DRIVE-CLiQ (CU): Sign-of-life fault
DC drive
Meaning: %2 Message class: Internal communication (DRIVE-CLiQ) fault (12) Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S Component: Power section Propagation: LOCAL Reaction: OFF2 (OFF1, OFF3, None) Acknowledgment: Immediately Cause: A fault has occurred in DRIVE-CLiQ communication between the control unit and the associated power unit. The sign of life from the DRIVE-CLiQ component to the control unit is not set. Fault cause: 10 (= 0A hexadecimal): The sign-of-life bit is not set in the received telegram. Note on the message value: Detailed information is encoded in the message value (r0949/r2124) as follows: 0000yyxx hexadecimal: yy = Component number, xx = Fault cause
