Baldor drive

[ptonsparky]

HW Saturation:

High output current condition detected (greater than 400% of rated output current). On B2 size controls, a desat error can indicate any of the following: low line impedance, brake transistor failure or internal output transistor overtemperature.

Started a seasonal operation today, attempted anyway, after a winters worth of moving equipment. An auger with a Baldor drive plugged & shut down. After clearing, resetting & getting it started again it will no longer operate the motor either with or without a load above 28 Hz. Same setup has worked for years @ 40 hz and worked part of yesterday and a good share of the morning. One of the faults is listed above.

We are about 300' from the service, #12 to drive, with line & load reactors, Voltage is 500+ which is typical for this plant. 5hp. I am guessing drive failure but sure would take some hints. A drive will be difficult to get tomorrow but can & will be done if needed.

At that sort of size, a new drive might be the best and most cost-effective option.
But I think you should check the motor too. Ground fault, output line current balance, winding resistance checks - all the usual stuff.

New drive did the trick. Had to rob Peter to pay Paul, but Peter is good until Wednesday.
