    Jun 09, 2009 That torque-speed curve shifts horizontally to the left as the frequency goes down. That's the key difference. So, when a motor is standing still, the drive starts it with 0, then 1, then 2, then 3hz. This is equivalent to shifting the torque-speed curve so far to the left that only the sync speed and a little of the curve is visible.

So '1' on the X axis means '100% speed', and '1' on the Y axis simply means '100% rated torque'. The blue line is the rated torque of the motor/VFD combination. Torque remains constant as speed changes.
