I have a 400hp motor that is running in sensorless vector control. After the original tuning and commissioning, the system was put into service. The process required roughly a 70% load for the motor. After a few days, the motor load for the same process conditions jumped to 98%. If the drive is put into V/Hz mode, the current returns to 70%. Load readings were taken from the drive keypad. Any ideas on potential causes?
