Control Stepper Motor with NI USB-6009

Hi All,

I'm currently trying to create a motion control system using a dual motion actuator

http://www.haydonkerk.com/LinearActuatorProducts/StepperMotorLinearActuators/DualMotionLinearActuators/tabid/67/Default.aspx

and two bipolar chopper drives (See attached) which should supply power to the motor. We already have a NI USB 6009 in our lab so I was wondering if I could use it to send the signals to the two drivers to control the speed and direction of each axis on the motor?

The attached driver manual states that the input signals must be 0-5 V DC (TTL logic). I have been told by the motor distributor that the 0-5 V DC TTL signals the drivers required, are analogue. From reading the NI USB 6009 manual there are two 0-5 V analogue outputs on the usb daq so I could supply two of the signals?

There are often similar problems posted however it is usually a digital signal that the NI6009/6009 is sending to the driver. From looking at the driver manual, can anyone tell whether an analogue signal or required like i've been told, or I have been misinformed and a 0-5V DC signal will be sufficient. I can get in further contact with the distributor if there are any questions you guys think I should ask him.

Thanks in advance for any help! It is much appreciated.
