F40895 — CX32 DRIVE-CLiQ (CU): Cyclic data transfer error

F40895 is issued on the G130, G150, S120 and S150 when a DRIVE-CLiQ communications error occurs on the link from the CX32 controller extension involved to the Control Unit. The fault is raised at the DRIVE-CLiQ Hub Module (Hub). The fault cause recorded for this code is 11 (= 0B hex): a synchronization error during alternating cyclic data transfer. The manuals of all four families describe the code identically, so the same meaning and the same remedy apply on every one of them.

• A DRIVE-CLiQ communications error has occurred from the controller extension involved (the CX32) to the Control Unit.
• The fault cause reported in this case is 11 (= 0B hex): a synchronization error during alternating cyclic data transfer.

1. Carry out a POWER ON (switch-off/switch-on) of the drive.
2. If the fault recurs, the remedy for this code cross-references p9915 (DRIVE-CLiQ data transfer error shutdown threshold master).

• The drive stores the component number and the fault cause in the message value, which can be read at r0949 (fault value) or r2124 (alarm value).
• Coding: 0000yyxx hex, where yy = component number and xx = error cause.
• For this code the error cause reads 11 — synchronization error during alternating cyclic data transfer.

• r0949 (fault value): shows the coded message value 0000yyxx hex for this fault, i.e. the component number and the error cause.
• r2124 (alarm value): the second location where the same coded message value is stored.
• p9915 (DRIVE-CLiQ data transfer error shutdown threshold master): the threshold the manual names in the remedy cross-reference for this DRIVE-CLiQ data transfer error.

The fault must be acknowledged immediately; while it is active the drive coasts down (OFF2) and does not restart until it has been cleared. The remedy the manual gives is a POWER ON: switch the drive off and then on again. No further reset or repair steps are described for this code.
