Other Parts Discussed in Thread: 2MTR-DYNO, , BOOSTXL-DRV8305EVM, DRV8305, SFRA, CONTROLSUITE, C2000WARE
Hello, i have a similar problem to this thread.
I have the same set: LAUNCHXL-F28379D, two BOOSTXL-DRV8305EVM's, and a 2MTR-DYNO.
I started working on the project in the title (and in the other thread) with the following voltage supply connected to the DRV8305's:
MEAN WELL
Model: UHP 1000 - 36
Output: 36V 19.6A
Jumpers JP1-JP5 are not populated, JP6 is populated, as the project suggested.
I followed the first steps (set MOTOR1_DRV and MOTOR2_DRV to DRV8305; Rebuild; Debug; CPU reset; Restart; Enable Real Time Mode; Resume; Set EnableFlag to 1).
While running the projekt (on Build Level 1), it stays in the loop below (FCL_SFRA_XL_DualServo.c)
#elif (MOTOR1_DRV == DRV8305) InitDRV8305Regs(&motor1, DRV1_GAIN); // motor1.drv8305.cntrl7_gd.bit.PWM_MODE = drv8305_PWM_mode_6; InitDRV8305(&motor1); while (motor1.drv8305.DRV_fault) ; // hang on if drv init is faulty #endif
because i have these error flaggs set (PVDD_OVFL, VCHP_UVFL):
The voltage supply is not adjustable, so the solution from the other thread is not an option (for now).
Also the DRV8035's supply voltage ranges from 4.4V to 45V, so 36V supply should be fine. Am i mssing something?
I would be thankful for any clue.
