Is there a direction input available on the driver unit for your dervo motor?

Mainstream servo drives control direct and torque (or velocity) via a +/-10V control signal. Positive voltages produce one direction of rotation, while negative voltages produce opposite direction of rotation.

Sounds like we need more details on you driver hardware

I got theree cable from servo. one is for +5v, 2nd cable for ground and 3rd one is for Pulse.So I have connected all wire in the DAQ.  I n generating pulse and it is running one direction.

Do you have literature for the servo? What does it say?

Manufacturer and model # would be useful, without any further info on your servo, I cannot suggest any thing.

I got the solution.
