Hi,

 

I am working on MTRCKTSBNZVM128 eval kit .

I am running Hall sensored motor algorithm firmware.

The sample code is provided by NXP itself.

 

Query is only 

Motor RPM calculation I found is to be incorrect.

Observing the HallPeriod array and Hall patterns,only 3 Hall pattern sequences are observed (4,5,6).

So the commutation is found to be not 120 commutation.

 

Please guide as to how to rectify the commutation issue,such that all hall patterns are observed.

Also I have another query.

I am using the ZVML64 where PT3-1 are used for Hall Sensor signals and IOCO_0 is used for capturing PWM input

Is it possible to use them simultaneously?

It was an hardware issue.

Rectified it.

Also would like to know MOTOR_STALL_1MS_COUNT,HallPeriodMax(10900) was defined?
