MCSPTE1AK344 encoder mode

Canberk — Thu, 02 Feb 2023 07:52:45 GMT

I have got MCSPTE1AK344 and I wanna operate pmsm motor with encoder. I set Encoder Macro to 1 and changed motor_pp and encoder pulses variables to my motor's specification but still I couldn't run the motor with encoder mode. there are some other changes that I need to make. I shared the changes that I make

Thanks

Hi,

Thank you so much for your interest in our products and for using our community.

To use the encoder mode, in addition to following the Getting Started you have to do the following:

Connect the encoder to connector JP1 (check DEVKIT-MOTORGD Schematics if necessary).
Change the macro #define ENCODER 1 and load the program on the board.
In FreeMASTER, Sensors tab define the resolution of the encoder (in my case 1000 pulses).

In the Project tree, go to Encoder Sensor/Speed

In the variable watch define the speed required

Finally change the state from STOP to RUN

And you can see the speed in encoder mode in the scope.

Hope it helps you. Please let me know if you have more questions about it.

Have a nice day!

Thanks for your answer. I tried your solution and I can see encoder speed value but I could'nt run motor with encoder mode. when I switch to encoder mode motor was vibrating.

How can I run motor with encoder mode
