官方故障排除步骤
Message value: %1 Drive object: All objects Reaction: NONE Acknowledge: NONE SINAMICS-Alarms Cause: The drive unit did not accept the receive configuration data. Alarm value (r2124, interpret decimal): Return value of the receive configuration data check. 0: Configuration accepted. 1: Connection established to more drive objects t han configured in the device. The drive objects for process data exchange and their sequence were defined using p0978. 2: Too many data words for input or output to a drive object. A maximum of 16 words is permitted for SERVO and VECTOR; and a maximum of 5 words for A_INFEED, TB30, TM31 and CU320. 3: Uneven number of bytes for input or output. 4: Setting data for synchronization not accepted. 5: Drive still not in cyclic operation. 6: Buffer system not accepted. 7: Cyclic channel length too short for this setting. 8: Cyclic channel address not initialized. 9: 3-buffer system not permitted. 10: DRIVE-CLiQ fault. 11: CU-Link fault. 12: CX32 not in cyclic operation. Remedy: Check the receive configuration data. Re alarm value = 1: Check the list of the drive objec ts with process data exchange ( p0978). With p0978[x] = 0, all of the following drive objects in the list ar e excluded from the process data exchange.
