I have a stepper motor (CS-M23480) with built in encoder for closed loop feedback which is connected to a driver CS-D1008 via a vga cable.

I have two problems:

1. I have no idea how to control the feedback from the motor to know its position; since there is no output connection from the driver into the arduino, so how am I supposed to know the location of the motor? Also, the driver data sheet specifically states that the R232 connection can only be using for tuning not for feedback.

2. the vga connection that came with the driver has 7 wires coming out of it instead of 6 with two black wires, one looks the same as the rest of the wires and the other is much thicker, and according to the data sheet the black wire isn't the ground wire, either.


any help is greatly appreciated

PS : I tried to upload the data sheets to ease the process but the site says they are too large to be uploaded here.
