7344 torque control

[jadcock]

I have an application for a double-ended 300+ HP dynamometer test stand. The input is in speed control and the output is in torque control. The 7344 is already set up to perform speed control, but our torque transducer output is a +/-5V. I have been told that closed loop torque control can be accomplished by routing the digital representation of the analog input channel as the encoded position, but I have no idea of how to do this. Example code – vi’s would be helpful. Thanks.

I am not sure I understand your application completely. You are setting up the 7344 to do a velocity move and now you want to use the +-5 volt signal as feedback to close the control loop? Let me know if this is how you want to do it in order for me to suggest something.
