text: <s>[INST] Can incorrectly programmed Motor NP Power parameter cause drive/motor failures? We've been having issues with drive/motor failures and I found that the VFDs were programmed as if the units were in HP rather than kW. So instead of being programmed to be 5 HP like the nameplate has, it was set to 5 kW. Could this cause any failures? [/INST] Carlos, Simply put - yes, what you have just described can cause motor (not drive) failures. One of the primary functions of a VFD is to protect a motor from overloading. 1 KW is roughly 34% more power than 1 HP. So if that motor is only loaded up to consume 5 HP, then there is no issue. However, if that motor is loaded to consume 6.5 HP continuously, it will burn up the motor over time. Basically the motor cannot dissipate the heat generated quickly enough and eventually overheats and fails. With the motor nameplate entered correctly, the drive would detect this overloaded state and fault. However, the drive should be unaffected by this since it is rated up to the maximum programmable power it can transfer, and when the motor insulation fails it should produce some output short fault. Now if you repeatedly restart the drive into a shorted condition, the drive can fail. It would be like dropping the clutch on a transmission after revving the engine to 8000 rpm (on a tradition sedan). The transmission can absorb this punishment a few times, but eventually if you kept doing this, it would fail. Hopefully this helps you troubleshoot the issue. I would strongly advise you reach out to our technical support team if you need further consultation. \\n </s>
