Question

What does the temperature spec of the drive mean? What is the conversion from Celsius to Fahrenheit?

Answer

The spec is –10*C to 50*C.

When the operating temperature is between 40*C and 50*C the following events must happen.
1.) The carrier frequency must be reduced to 2.1 kHz
2.) The output must be derated to 80%
3.) The top cover of the drive must be removed (this also nullifies the NEMA rating of the drive)

The conversion from Celsius to Fahrenheit is: F = 1.8 x C + 32.0
