Ok. This is what I have so far.
I checked the VDC output from the power supply to the Stepper Driver and it was 24.25 Volts.
I called Kollmorgen and spoke with their technical support because I couldn't find a connection diagram for the 8-pin layout my motor has.
The link to it is here, http://www.kollmorgen.com/en-us/products/motors/stepper/_literature/stepper-and-synchronous-motors-catalog-en-us-revc/
On page 94-148 the motor’s Connection Information can be found under Part # GW0000F (8 Lead). The wire connector I was sent is wired for a Bipolar Parallel connection (verified). My wire connector is using the same color code that can be found in this .pdf.
Black to Phase A+
Orange to Phase A-
Red to Phase B+
Yellow to Phase B- All connections were verified
I checked with my voltmeter Pin # 9 or Direction Pin. It does give me voltage in the beginning of the program as expected, Value measured = 4.95 Volts
I checked also Pin # 8 or Step Pin. It never gave me any voltage reading even at 2,000,000 μsec or 2 sec pulses and 5,000 msec or 5 sec intervals.
I used your code dated, Edit 23 Jul 2016.
By the way, thank you for the "How to insert an Image" guide.
