I build a platform, using STM32 send copley drive pulse, and the driver maxon with dc motor, the experimental purpose is to want to change the STM32 pulse duty ratio change the motor speed, but in the STM32 timer sends a pulse frequency constant, change the pulse duty ratio, the motor speed is constant, would you please tell me why this is, and the parameters of the drive performance about, thank you,
CodePudding user response:
PWM has changed, only level amplitude, did not change the pulse frequency, for dc motor speed can be changed, but for the stepping motor of pulse, will not change the speed,
CodePudding user response:
Problem has been solved, is copley drive configuration problem, should be configured as PWM mode, only can be achieved by changing the duty ratio change, the purpose of motor speed problems before because drive configuration in the direction of the pulse mode,
