Can i connect an external signal generator to the NI7344 to use its PID characteristics to precisely control the output
I am using the flex motion board (NI7344) to control the force output of a linear motor. Using contouring and buffer operations i have successfully created a system which can output a controlled force which sinusoidal in form. I can achieve a reasonable output for waveforms of 10Hz, the use of higher frequencies is limited by the contouring operation ( a frequency of 10 Hz means i can only describe one period of a sine wave with 10 points ( 10ms between each point = 10Hz). Can i therfore connect an external anologue wave generator to the NI7344 use and use its PID characteristics to output wave forms of higher frequency ??? .....could i output an anolgue wave form from an E-series DAQ via the RTSI cable to the NI7344 and control this ???.any ideas or advice would be much appreciated.
You can use a DAQ card to output an analog waveform, but it will be a software call not part of an onboard program. RTSI can be used to pass clocks and trigger signals, so if you want to route a clock signal to do the control you could.
