SoftMotion with Analog Input Position feedback

[Kalluru]

Hi,

I have a cRIO system (9025 controller, 9269 Voltage Output and 9229 Analog Input module) which I wants to use in motion control application.

I have a third party drive (Maxon), which will accept -10 to 10V set point and feedback from the motor is also analog signal of -10 to 10V.

With the above configuration, is it possible to use SoftMotion? if so, where exactly I need to map the AO and AI channel in AXIS Configuration. Sharing any sample code available with the above requirements is really helpful.

Hi Bhaskar,

I'm no expert, but there are some examples in the NI SoftMotion module to get you started.  One example that comes to mind is the Basic Servo (9263 & 9401) example.  9263 is an AO module like your 9269, but the 9401 is a DI module that accept digital encoder signals, unlike your 9229 AI module.  You'll have to do some modifying of the code to fit the modules that you're working with.
