MCF8316A: MCF8316AEVM Performance problem

yingjiao LI

Part Number: MCF8316A

During the test, the product was powered on to control the motor operation. The first time it was powered on, the operation could be controlled eventually, but the start-stop control and speed regulation control could not be carried out, and the voltage recognition was deviated from the actual value.
Could you please help confirm the cause
thank you

Hi Yingjiao,

You are toggling DRVOFF signal. Motor faults may have triggered and if the fault is latched repeated ON/OFF will not recover.

Can you check configuration file for fault mode setting (No motor, Abnormal BEMF and Lock Retry times)

Can you connect to GUI and read fault . In your video Fault LED is not visible clearly.

Thanks and Best Regards,

At present, we can only turn on the motor once and then turn it off. Under normal circumstances, the motor cannot be used, and the fault alarm will be generated. However, the abnormal part cannot be used directly, and it cannot be read when connected to the computer.

The problem is: there is no fault state and alarm, and then can not control the switch, this problem is not always, or the communication will not be connected to the board and the gui communication, very unstable
