Posted on August 25, 2017 at 11:12Hi,
i'm using the a STEVAL-IHM034V2 board for evaluation (PFC + FOC PMSM).
I imported the project in ST Workbench 4.3. Generated files and compiled with IAR is OK. Then board is programmed.
The motor starts but the PFC doesn't work.
I verified in the file Drive parameters.h that the PFC is enabled : the following line is present
#define PFC_ENABLED /* #define PFC_ENABLED to enable the PFC */
so the PFC should be enabled.
With serial communication i get the PFC_Status = 0x10
(Id 0x4D)
and the PFC Flags = 0x00100010
(Id 0x4E)
which means that the AC frequency is not in the correct range. The AC Mains Frequency is read as 0 with the serial communication (Id 0x51).
The pin for AC Mains is B4 (Timer 3 channel 2)
With an oscilloscope i measured the frequency on TP7 on the board, i have a square wave with 10ms period so the signal is OK.
Thanks
Philippe
