I'm trying to do "6 Incremental build level 1" in "Quick Response Control of PMSM Using Fast Current Loop".

In "Figure 5.", the state of rumMotor is "MOTOR_RUN".

Originally the value of "runMotor" in example code is "MOTOR_STOP".

So I tried to change from "MOTOR_STOP" to "MOTOR_RUN" during debugging mode.

But, the state was not changed.

everytime I tried to change the state, I failed.

Is there some special setting?

Please let me know.

thank you.

I suspect the system sees some overcurrent protection signal or so. Check the status of TripFlagDMC. If it is set, try to clear it by setting 'ClearTripFlagDMC' to 1. If it does not help, you may have to verify the analog signals sensing the current feed back.

I am solving hardware problem. So, I will try your suggestion after solving the problem. Thank you.

Thank you for your reply.

'TripFlagDMC' is not set. In the below figure, 'TripFlagDMC' is not set. So, i think it is not no OC protection signal.

By the way, you said 'If it does not help, you may have to verify the analog signals sensing the current feed back'.

However, I didn't connect encoder and motor's UVW and I used 15V 2A adapter.

Do you mean I have to check M5(LEM-CurrentSense) and M6(OCP)?

In addition, I can check PWM wave in 'incremental build 1' according to application notes. Is it right?

Thank you.
