HITEC servo control with NI-USB 6351

[dani89]

I have a servo motor from HITEC (model HS-805BB) and the multifunction DAQ card NI-USB 6351. I would like to use the counter/timer terminals of the card in order to send a PWM signal to the servo and control its motion. How should I make the connections? Do I need to have an additional circuit to provide more current to the motor?

I am very new to motor control, especially when it comes to electronics.

Thank you!

HI dani89,

I took a look at the specs of your servo:

It seems that it calls for a pulse of 3 - 5 volts, which the 6351 can supply, so I wouldn't worry about using amplification at this point. 

As for the connections, you should be able to simply connect your digital lines to the servo to transmit pulses. Have you already begun programming your PWM through hardware timing?
