Other Parts Discussed in Thread: MCF8315A, MCT8316A
Hi Team,
Motor control:
Open-loop control: PWM signals with different duty cycles are directly output through the FPGA.
Closed loop control: Sets different speed and controls the PWM signal through PID algorithm.
Issue:
Open-Loop Control: when start-up, the motor is stationary or swings left and right. Both RD and FG signals are high at this time, and RD and FG signals are shown in Figure 1, the motor controller chip lock is shown in Figure 2.
Closed loop control: the issue is as same as the open loop control's.
This issue is not common and only can be seen on one device. The motor runs normally at the beginning, with occasional start-up issue.
Figure 1
Figure 2
And please see the circuit below:
Could you help check this case? Thanks.
Best Regards,
Cherry
