I/O range - 0378 - 037f
under that is another I/O range;
0778 - 077f
under that;
DMA 01

Just for drill, try setting Port #1 to 778.

Hi Rick

Not sure if you got an answer to the compatability issue..... I am using md808's and they work fine. Like others have said if the motors lock when you power up that is fine.

Couple of questions:

Have you supplied 5vDC to the opto input?
is the power led on and the fault led off?
have you set the dip switches in the rear for the nuber of micro steps and current limit suited to your motors?
Your motor windings should be about 3ohms and open crt between them.


To make the drive work you only need:
opto.... 5vdc
pulse.... clock/step signal
dir... direction signal.

BTw these aere chopper drives and the comment that the ps voltage devided by the winding ressistance is the current draw is incorrect. the current limit is set by the dip switches and should vbe set to what is shown on the motor. ie 2 amps.


cheers
Mark

Thanks for the info Mark. I finally got up and running a couple of weeks ago. A separate 5v feed to my parallel port interface card was what was needed. She works fine now. Just been trying out different cam software and decided to go with Vectric products. Seems to be very easy to use and I like the results for what I'll be using it for. Thanks again.
