Hi Sir,
evm : DRV8301-69m-kit
motorware ver : v15
application : e-bike
motor pole pair : 7
user.h USER_MOTOR_MAX_CURRENT (5.0) --> for test
I used lab04. Iq=2.0 the motor run max speed = 3.4Krpm, I increase loader, the speed is no variable. when the loader is overhead , the speed is quickly count down to "0". then release the loader. The speed come back max speed.
I have used lab03b to test as below:
1. Set the SpeedRef_krpm = 3.4Krpm, I increase loader, the speed is no variable. when the loader is overhead , the speed is quickly count down to "0". then release the loader. The speed come back max speed.. That's as the same as the lab04.
2. Set the SpeedRef_krpm = 2Krpm, I increase loader, the speed can count down. When I increase the loader , the speed can be variable.
I don't know why ? If the motor run max speed. I increase the loader the motor can out of control ???
Please help me to solve it, thanks a lot.
