Well it is sort of.. in that it seems everything is working OK...

you can safely measure the voltage output by testing with a meter in parallel but current is a bit more difficult.. as you have to put the meter.. and yourself in series connection with the supply to do this...NOT RECOMMENDED unless you know exactly what your doing..... alternatively you can use a clip on meter designed to measure current using induction... but not many people have one of these lying about...

Best thing to do is try the motion against resistance.... GENTLY try and stop the axes from moving... if they have a good amount of torque then along with the speed test you performed this would suggest that all is working ok...
