Welcome to the forum. That appears to be a standard L297/L298 setup. Should probably work fine.

If you want to build a drive, you should also check out www.pminmo.com . He has details for many different drives. This one http://www.pminmo.com/l297-8/l297-8.htm should be very similar to the one you linked.

Well, thanks for suggestion...

But i have 2 bipolar and 1 unipolar motor for my CNC-mashine
And i found something, well at least i think is error.,.
Look at this driver

I says that is unipolar driver but it only have 4 connectors for motor..?!
So i decide for this french version..
Thanks

Don't unipolar motors work on bipolar drives if wired differently?
