Try bumping up the minimum hz to like 20 and see how it does. At 5 hz the motor is probably not going to generate any useable torque anyway. (Please disregard this advice if your not running a common 2 or 4 pole induction motor)

I'm on my way down to the shop right now...I'll give that a try and report back! If that solves the problem I owe you a case of Dom Perignon.
