Hello Riddersholm, Have you noticed which was the fault code displayed on 611A spindle drive module? Does your spindle has direct mounted encoder i.e. encoder mounted on spindle shaft (apart from motor encoder). Where spindle encoder is inetrfaced? i.e. to drive or controller/PLC? Since you are suspecisious about temp related issue, have you checked temp inside cabinet after 24 hrs operation? How much is ambiant temp? How much is percentage loading of spindle drive? Please check above points which may help to analyse/daignosis problem. HTH |

Hello Riddersholm, Few questions - 1. How you measure PLC input signal interuption time (35 msec)? 2. You mentioned M19 spindle orientation shifting problem? I guess, there must be gear box between spindle motor & spinlde shaft. Check if M19 works only at particular gear stage. Cross check if any relation exist between the ocuurance of problem if the spindle works with the same gear stage.
Is the same spindle motor is used for it or other motor is used for M19 operation? In case of M19 orientation operation, there must be BERO sensor (proxy) for spindle position idetification, check if its operatinng dog position is loose. Check the tention of drive belt, if it is timer belt -check tooth condition. Confirm there should not be any chance of transimission slipage. Does your spindle has clamping, hydraulic or mechanical)? If yes check its correct operation. HTH |
