MCT8316Z: Calculating max motor current

My customer question:

I was referring the attached sheet for calculating the maximum current supported by the MCT8316Z device. The sheet is downloaded from https://www.ti.com/. I have few queries related to same.

Can you please clarify what is Motor Electrical Frequency and PWM Frequency?
