官方故障排除步骤
Message value: Fault cause: %1 Drive object: All objects Reaction: A_INFEED: OFF2 (OFF1) SERVO: OFF2 (OFF1, OFF3) VECTOR: OFF2 (OFF1, OFF3) Acknowledge: IMMEDIATELY Cause: A fatal error was detected when downloading a project using the commissioning software. Fault value (r0949, interpret decimal): 1: Device status cannot be changed to Device Download (drive object ON?). 2: Incorrect drive object number. 3: A drive object that has al ready been deleted is deleted again. 4: Deleting of a drive object that has already been registered for generation. 5: Deleting a drive object that does not exist. 6: Generating an undeleted drive object that already existed. 7: Regenerating a drive object al ready registered for generation. 8: Maximum number of drive objec ts that can be generated exceeded. 9: Error while generating a device drive object. 10: Error while generating target topology parameters (p9902 and p9903). 11: Error while generating a dr ive object (global component). 12: Error while generating a drive object (drive component). 13: Unknown drive object type. 14: Drive status cannot be changed to Ready (p0947 and p0949). 15: Drive status cannot be changed to Drive Download. 16: Device status cannot be changed to Ready. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 17: It is not possible to download the topology. T he component wiring should be checked, taking into account the various messages/signals. 18: A new download is only possible if the factor y settings are restored for the drive unit. 19: The slot for the option module has been configured several times (e.g. CAN and COMM BOARD) 20: The configuration is inconsistent (e.g. CAN for Control Un it, however no CAN configured for drive objects A_INF, SERVO or VECTOR ). Remedy: - use the current version of the commissioning software. - modify the offline project and carry out a new download (e.g. compare the number of drive objects, motor, encoder, power unit in the of fline project and at the drive). - change the drive state (is a drive ro tating or is there a message/signal?). - carefully note any other message s/signals and remove their cause.
