Super Vexta UDK5114NA Drive

Hi, Can anyone tell me if this drive can be driven by step/direction from output Mach3.

Information on these drives is hard to come by.

Thanks.

Hi, I came a cross this link for information on 5 phase Vexta Drives and Steppers in another thread in this forum.

Yes, you can control these drives by setting the Pulse Input Mode Switch.
This is true for Super Vexta UDK5114N but not sure about Super Vexta UDK5114NA

Does any one know what the A stands for?

The UDK5114NA drive can be used with step and direction signals. They have a switch near the top that says 1P or 2P which means 1 pulse or 2 pulse. Use single pulse for you application.
Another type of Vexta UDK5114 drive doesn't have any readily accessible pulse switches on the outside but if you look inside the cover there is a small red switch on the back of the circuit board that isn't marked and this is the 1 pulse 2 pulse switch.
They are a very good drive and I will be using a few of them for my next router build. A 800mm x 800mm router and 200mm Z axis which is nearly finished.
The biggest problem I have is with step down transformers and finding a suitable one at the right price is very hard, unless you want to pay $225 for one.
The UDK5128N is the high speed type and with a size 23 motor I was able to get 1,140 rpm out of it (but not much torque as you know) I tried it on a 34 stepper and could only get 800 rpm out of it before it became unstable so I guess motor induction plays a significant role in the top speed.

There is plenty of information out there for these drives but you have to know where to look. :-)
