Hello minhdat, Please do not change any parameters since it is not related with any parameter setting issue. Since this test is obligetory, it must have valid reason for it & let us honor design procedures & try to maintain those instead of trying to bypass or play with it. Now as your alarm indicates overtravel, brake is not operating at its rated capacity. (I guess this brake test purpose is to cross check the working of rated torque of brake & in your present case, brake operation is failure) So check if the brake is external or servo motor brake. If external brake, check type of brake i.e. whether hydraulic or electromagnetic. If hydraulic type, check the hydraulic pressure. If electromagnetic, check brake coil resistance & its brake plates. In brakes there are two types of metal plates, - 1 with gear tooth is inner plate 2 with out gear tooth - outer or pressure plates. You need to check, if those are wear out or bend. This will cause detoriation of brake torque. If needed take help from local expert for testing of brake. If brake is inbuit in servo motor, I suggest you to get it repaired from your nearest Siemens support center. HTH. |

Thank you ! you guided very clearly . we tried changing parameter of brake torque at no.36966 reduce 20% however the machine inform error . Thanks All ! I already understood this problem , this problem is at servo motor and DMG service in VietNam. what is note ? when we replace new motor as reference for position or encoder |
