Hi Peter > Where did you measure the current?
I measured one phase. > (you may indeed measure 600mA in the power > leads with current limiting (7.5A) in the driver) The 600 mA was mistake, current reaches 3.5 A actually. > If you see a red LED light on the 7I39, you have reached the current limit Oh, in deed it dose light up, it flickers a bit, though. I'll pull the current limit jumper and report back. Thanks. > Another thing to check is that you have not somehow limited the max PWM value > so you are not getting sufficient drive voltage (PWM does not get near 100% > or > near 0%) This would be done using hal scope, right? I'll try that.
