UDC-HI error while running a 24V PMSM with DEVKIT-MOTORGD

steven_zhang — Tue, 27 Apr 2021 03:44:05 GMT

i cut the short-circuit line of J15 on DEVKIT-MOTORGD board so i can power the board and S32K144 board with an 24V adpter and driving a 24V PMSM. but i got UDC-HI error with below settings,how to set the voltage limitation for MCAD.

#define I_MAX (31.25F)
#define U_DCB_MAX (45.0F)
#define N_MAX (3500.0F)
#define WEL_MAX (1099.56F)
#define E_MAX (36.0F)

//Application Fault Triggers
//----------------------------------------------------------------------
#define U_DCB_TRIP (40.0F)
#define U_DCB_UNDER (16.0F)
#define U_DCB_OVER (30.0F)
#define I_PH_OVER (5.0F)
#define TEMP_OVER (110.0F)

Hello Steven,

Thank you for contacting us. I would need more details to help you.

Are those macros you printed here copied from MCAT tab - Output file or from PMSM_appconfig.h file?

Could you tell me version of the SW you are using?

When does this fault occur? immediately or during motor operation?

Does it work at 12V?

Thanks!

Regards,

Marek

thanks for your apllier

Are those macros you printed here copied from MCAT tab - Output file or from PMSM_appconfig.h file?-----from PMSM_appconfig.h ，but the macros are the same.

Could you tell me version of the SW you are using? ---------- S32DS for ARM 2018.R1 and MTRDEVKSPNK144_S32DS

When does this fault occur? immediately or during motor operation? -----immediately.

Does it work at 12V? ------it works at 12V for some low current motors such as a Linix.

I would recommend to download latest SW from product page:

https://www.nxp.com/mcspte1ak144

Nevertheless, could you make a snapshot of the FreeMASTER variable as below?

Marek
