故障含义：The DCM (Drive Communication Master, an ASIC on the NCU module that takes control of the drive bus) has not signaled when powering up the drive. In the 840D, a hardware fault is the possible cause of this error. (For the FM-NC, an incorrect configuration is also possible via the NCK MD 13010 DRIVE_LOGIC_NR).
