Some body know abaut Delta asda a2 servo and drive

You need to Enable the servo circuit. Quick look at the manual tells me you use pin 9 on the Digital inputs.
The way this is done is using relay that turns on all the the drives at same time using the Enable OUTPUT of PMDX. So when Mach3 is Enabled it takes control of the motors.

So Relay Coil is controlled via PMDX using Enable OUTPUT. Then Run the wire from VDD on drives thru the relay contacts and back to Pin9.

Thanks, i work this weekend on yours directions and i let know the outcome

I follow your instructions and i get movement from the servo motors I slave "A" motor to "X" axis, now the problem is the movement is to slow, on the asda a2 manual said "1280000 pulse/rev" but in mach3 said 2000 steps, which is a good number for that box in tunning window and get a good rapids.

The steps Per setting is not something you can guess or what sets the Rapid speed. It's an exact number which ensures you move the correct distance for one unit of measurement derived from calculation of the Encoder Resolution divided by the distance traveled for Revolution.

So if your Encoders are 2500ppr and they are quadrature this number becomes 2500 x 4 =10,000ppr. And your using Ballscrews with 10mm pitch connected directly to the motors. Then the steps per setting would be 10,000 / 10 = 1000 Steps per.

However if your using a Ratio to connect screws to motor, which with servos you probably will be doing then calculation gets a little more involved. See the Mach manual and it will explain how to calculate this depending on your setup.
