INSTASPIN-BLDC: Cant get Insaspin running with own inverter

Daniel Ruescher

Part Number: INSTASPIN-BLDC
Other Parts Discussed in Thread: MOTORWARE

Hi,

I'm trying to get my own inverter running with Instaspin.
I am using a lauchxl-f28027f and Lab_2b for motor identification.

In the Instaspin gui it is not possible to enable the the system (Checkbox)
I already changed the parameters for voltage and current sensing.

I added the wiring to the attached circut diagram

Is there a problem in my wiring?
Or is it impossible to run instaspin without the drv Ic?

Wich parameters in the code do I have to change?

Kind Regards

If you are running InstaSPIN using your own hardware without a DRV83xx device, I would recommend using a lab that's for the High Voltage kit as it doesn't rely on a DRV IC either. Also, please use labs 1b/1c from Motorware 18 to determine if your signal chain circuitry is correct before moving on to ID'ing the motor.

Thank you for your answer!

If I run lab 1b it says no error.
Also I can run motor ID it measures all the offsets correctly and says motor itentified.
Measuring the speed of the motor is also possible.

There are no PWM Signals from my launchpad.
PWM's were connected to GPIO0 to GPIO5.

For current measurement I´m using ACS711 Sensors

What could be a typical error that there are no PWM signals?

Kind Regards

Are you successfully entering the mainISR?

Yes, it reaches the breakpoint on the line " CTRL_setup(ctrlHandle);"

Also there is no signal on the PWM ports during LAB1b/c...
