Help VPI SDS Issue

I took the plunge and got the SDS. Wow what a difference but I am having an issue. (I am using the 600 rpm motor) In order to get the motor to spin the platter I have to push it to start it moving. The motor is on but it sound like to is hesistating. I unplugged the SDS and no issue it starts right away. Is this an issue with the 600 vs 300 motor?

If I'm not mistaken, the only voltage adjustment available for the SDS is for the 'steady state' voltage, i.e. the SDS always starts at 115v (for maximum motor torque), and after a few seconds drops to whatever 'run', or 'steady state' voltage you've selected (for a more quiet motor).

I've got a feeling that the issue is the 600rpm motor-I've never had a problem with my Aries 2.
