Description
SIEMENS CNC servo drive
Model: IFK7083-5AF71
Failure phenomenon: ALMll21 alarm
Failure analysis: the model for the German SIEMENS (SIEMENS) 802D system dedicated servo system. ALMll21 alarm is the meaning of "follow error of Y axis is too large (YCLAMPING MONITORING)" manual movement Y axis, found on the CRT Y axis coordinates display changes, but the actual Y axis servo motor without movement, when the Y arrived that follow error limit machine parameters after the set, namely 1121 alarm. Check the servo unit of the machine tool, when the fault occurs, the corresponding servo controller on the H1/A warning lights, said the servo motor overload. According to the above analysis, the failure may be caused by the resistance of moving parts. In order to determine the fault position, the maintenance will be servo motor and mechanical parts from, inspection found that the mechanical load is light, because the Y axis of the tool is the use of servo motor with a brake, initially identified the failure was due to defective brake. In order to confirm the operation of the servo motor brake, by adding the external power supply, to confirm the normal operation of the brake. Further check the brake connection line, found that the brake power supply connection is poor, cause the brake is not able to completely loose; re connect, the fault disappeared.
Failure repair: after the connection of the brake is firmly connected to the normal power.
