The curve shows pps- pulses per second. If you use 1/2 stepping, 400 pulses represents 1 rev. which figures to 17.5 rev/sec which is 1050 rpm where you are getting almost no torque.
Sw5-8 control stepping. The one entry missing from the table is all switches on- that may give you full steps, or might fry the driver. Check the manual.
I also tried the combination of ON ON ON ON - thinked that would be fullstepping but its not, its much more precious than 400steps/rev.
Someone on the forum told me about inductance, that I should have around 90-100 volts of voltage from powersupply for 6.8 mH of inductance.... what do you think?
