s32k144 pmsm control

Hello ,

Since open loop control of pmsm doesnt require voltage measurements , we were trying to remove unnecessary blocks . When we commented out the ADC blocks shown above , the motor doesnt run and pwm is also not generated. We commented out the fault block which took Vdc and Idc as input.

Can you help us understand what's wrong

Hello Sriram,

Here you can find the modified project as you want (without Vdc bus and Idc bus measurements and protections). We use to add those two parameters for protection.

I think your project didn't work with those two parameters removed due to another interconnected block (PDB config block). This PDB block is used to trigger the ADC measurements. So the ADC measurements were triggered but were not read.

Best regards,

Adrian
