1800rpm (or a little less) would be 2 pole pairs. That could be affecting your motor's behavior when it tries to spin. I had it set to 2 pole pairs by default.

It's a german motor so I would expect the numbers to be based on 50 Hz. Motor is rated to 9700 rpm, so would it be 165 Hz for a 2 pole motor, 330 Hz for a 4 pole motor, or just under 500 Hz for a 6 pole motor?
