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