Other Parts Discussed in Thread: TMS320F28377S, DRV8316
We are using the DRV8316REVM. Here are our observations:
- We set control register 2 so that we use PWM_Mode 3x (no current limit). Under these conditions, we cannot move our motor. If we change reserved bit 6 from 1 to 0, then we can move the motor as we desire.
- If we set control register 2 so that we use 3x mode with current limit, then we cannot get the motor to move, no matter how reserved bit 6 is set. The current limit on the board is set to 8A, which is far beyond what we need for this motor.
Can you explain this behavior?
