Lab10a not working

Other Parts Discussed in Thread: DRV8301, LAUNCHXL-F28027, MOTORWARE

Hi,

I'm working with a DRV8301 board and launchxl-f28027 board. Besides this, I use the teknic_2310P motor. I followed step by step the Lab 10a but the motor never spins, no matter the value in gMotorVars.SpeedRef_krpm.

Bellow a screenshot with the values into the main variables (svgencurrent.IgnoreShunt is in a loop…ignore_a-ignore_b-ignore_c).

I have checked the motor with others labs and it’s working fine, but not with this lab. Any suggestion?

Many thanks in advance

Could you please try downloading the newest MotorWare v17 and trying lab10a from that release?

We recommend that pwm and ctrl loop have same frequency for OVM functions in lab10a.

So, please change the following two defines like this by default in user.h . The USER_PWM_FREQ_kHz can be manipulated properly for your system.

#define USER_NUM_PWM_TICKS_PER_ISR_TICK (1)

#define USER_PWM_FREQ_kHz (15.0) //
