RPM vs Torque curve

Yau Tsang

Hi, just a quick question here.

Is it possible to plot a RPM vs Torque curve with Code Composer Studio? I've been attempting to do so with the graphs tool (Tools > Graph), but I haven't found a way to have both gMotorVars.Torque_Nm and gMotorVars.Speed_krpm plotted against each other on the same graph.

Thanks.

have you tried looking at the example in InstaSPIN_motion proj_lab05f?

Chris,

Yes, it opened up two plot windows, with plot A showing Speed vs time and plot B showing Torque vs time. Ideally, I want the speed to be the x-axis, and have the torque as the y-axis, both in the same graph.
Both 'Single Time' and 'Dual Time' graph tools seem to have 'time' as the mandatory axis variable just as the names suggest, and they don't give me the option to change that.

I'm sure this can be done, but I haven't.
Let me move this to the CCS forum and see if we can get a response.
