I checked power cable all the possible pairs of any 2 wire leads - there are no shorts. I connected the motor directly to 7i39 card (with very short (~30 cm) test wires) - it works just fine. Also jogging, when linked to PID (I had to hold it by hand to create at least some kind of load, otherwise it goes wild) works great. So the problem was in the cable. I already started to think about replacement cable and somehow decided to check it all once again with multimeter and while trying to put one multimeter leg to a particular pin in plug in motor end, I noticed that one wire seemed too loose than it should be. Little surgery of plug body with knife and I found that the wire had broke off of the pin leg. It was a matter of good luck for multimeter to show this particular wire lead to be ok. The end result is - a little soldering and problem solved! Machine works!
