Recording motor amps and battery amps

Hi.

I have a problem with the SBL2360 controller.
When making a step-response in open loop from the input 300 to 550 and recording the data, I can easily record the setpoint (input) and the encoder RPM (output) with a samplerate of approximately 10 Hz.
I would like to add motor amps to my recording in order to get the parameters of the motor I'm using, but when I record the amps, a lot of the samples are NaN and the samplerate is drastically lowered.
Is there a way to record motor amps at the same rate so I can calculate my parameters?

I am using the most recent firmware version for the SBL2360 (v.1.8d, January 08, 2018)

EDIT: I am only using the Robteq+ software, not Microbasic scripting

It is curious that you are seeing logged NaNs. Our controllers do not currently use any floating point values that are accessible from their query interface, so I imagine that the NaNs are originating in Roborun+ itself.

Post an example log with the NaNs. It will help provide some troubleshooting insight. The key should be finding out where the NaNs are being generated, since it should not be on the controller.

Hi Gabriel

I have posted 2 txt files in the first message, one with the NaN's and one without.

When plotting the signals and working with the data, I am using Matlab.

I have found and fixed the issue. I am living in Denmark, the data from the motor amps are separated with a comma "1,2" and Matlab can only use periods "1.2".

I just opened the .txt file, changed the commas to periods, and now it works

Haha, yep, I run into decimal confusion all the time. Glad you figured out what was going on!
