ODU Compressor Running Issues

VGani.1
Associate II

Hi, 

I am using STEVAL-CTM010V1 to drive the compressor. I am using Workbench 5.4.7 for dual motor control. I am able to run the Drive2(Fan motor). when it is running, I am trying to run the compressor. Immediately, communication is getting disconnected. What could be the reason? Please Suggest. 

 

Thanks&Regards

Vijay

Hello,

It could come from the fact that CPU is overloaded, could you please try by decreasing PWM value (from 20K to 15K e.g.)?

hi @GMA 

Currently, the PWM frequency of Compressor is 6kHz.

Hello,

Unfortunately, Workbench 5.4.7 is no more available on ST site (for STEVAL-CTM010V1, example is available with WB5.4.8 or it is available on WB6.2.1) and I cannot check on FW side but could you please check with a debugger if an error has not been trigged internally and not reported to the tool? On WB5.4.8, a table STM[] contains a "fault occurred" variable.

Hi,

On WB5.4.8, a table STM[] contains a "fault occurred" variable. Can you just send me a screenshot where we can see these values in live expressions??
