hi guys there is an alarming rate at which these type of drives are failing in our company.are we missing an important parameter?.in one machine alone in a span of 6months we changed two of them.one was giving a groundfault alarm which you cant reset even if you disconnect the motor.we changed to another one which after a period of 3months could not give any output the BOP just went blank.
apparently the same faults appear to other drives in other machines.recently we also lost an ABB 11KWDRIVE with the ground fault alarm.the delta and sinamics type we havent lost any since we installed.
the dc drives also from siemens these are worse they burn the fuses plus the scr in the drive. what can be the problem here?:no::no:
