text: <s>[INST] PowerFlex DC Drive current limit Summary: How to achieve drive full O/L capacityIt seems that the PowerFlex DC drive will only allow an output current capacity relative to the motor name plate FLC, regardless of being in ND or HD mode, and will not output anymore current even though the drive is overrated for the motor. My situation is the motor FLC Parameter[179]=180A therefore the drive will only output 150% & 200% in ND mode = 270A/360A and 200% & 250% in HD mode = 360A/450A, even though the capacity of the drive is 250A (150% & 200% should be 375A/500A in ND mode). We are installing on a Steel Mill roller table which requires +425A at times on heavy sections. Any thoughts or advice please. [/INST] The drive may be oversized relative to the motor, but that's the point of parameter 179. Giving the motor nameplate current will permit the drive to set the overloads relative to the motor. 200% overload for your 180A motor is rather less than 425 that you want. Is the PFDC replacing something, or is this a new installation? Your statements would make it seem the DC motor is undersized for the loads. \\n </s>
