I finally got suspicious as it was staying so cool with the fan on it and read several sections of the manual. The page describing the error codes wasn't very clear at all. "electronic overtemp" sounded to me like the drive was overheating, but what they really meant was the digital motor protection function had decided the motor averaged above nominal current for too long. So, I turned that feature off and did 160 holes last night. The motor never got above warm. It is designed for plug reversing off 440 V mains.
I do have a braking resistor on it, and it gets a little warm, but that's all. Without the resistor, it would get overvoltage alarms.
