AWV compressor vfd output high
Issue with two AWV’s where line side of breaker for both units had cables stolen. After cables were replaced I’m running into issues with the output side of the VFDs having high amps and compressors are unable to stage up with the high amp draw. One unit is using Yaskawa A1000 drives and the other is using Danfoss VLT drives. I can see in the Danfoss drive that the motor current is set higher than what the compressor is rated for. I don’t have any submittal info on these units. Does anyone have info on setting up paramerters on these drives or seen this type of issue after power failures? Waiting to hear back from Daikin tech support and plan on getting on the phone with Danfoss and Yaskawa tomorrow morning
