I've started setting up my VFD, but can't get very much speed out of the spindle. Display shows about 8-12Hz and spindle is turning very slowly and whistles slightly.

Spindle is the 1.5Kw water cooled one from 'lovehappyshopping', freq 400Hz, speed 8000-24000rpm, 8A, 3phase, 220V. Checked the windings with multimeter and there are no shorts.

VFD is Moeller DV51-322 (1.5kW). I so far have set the following:
H203 (power) 1.5Kw
H204 (poles) 2 (also tried 4)
H207 (voltage) 230V
A016 (max current) 8A

A003 (base freq) 133Hz
A004 (max freq) 400Hz
A044 (V/F mode) linear constant torque

The rest I've left as defaults. I've also installed drive software on my PC which enables easy viewing of the rest of the settings. There are perhaps 100-150 settings listed and I don't know which ones to change to get the spindle to run quicker.

Any ideas?
