While measured output DC link voltage is 540V while power on condition and after enable given it slowly drops to 100V !!!. I seperated the DC link from the other motor modules and tested again we have same result. What could be the possible fault.? BLM faulty ? Because the drive system was Just commissioned and it was working fine. All of sudden while power On we have these fault and not able to reset this. Any suggestions Please. Thanks in advance.
