IONI BLDC motor Commutation

When commutation from IONI, I wonder about the amount of movement.
Could you give me an answer?

My hardware configuration:
-BLDC motor Lineaer

Hi Younhwan

Assuming position mode, one step pulse (or quadrature pulse) will result in movement of one encoder CPR step. This also assumes MUL = DIV in the configuration parameters.

If the linear encoder has total resolution of 1000 pulses/mm, then that amount of pulses is needed in order to move the motor 1 mm.

Detailed configuration instructions are here:

Kind regards,

Dear, Esa
I do not understand your answer well.
What I would like to know is that when commutation runs, I want to know the approximate moving distance. I am using a resolution encoder of 100pulse / mm. At this time, I would like to know the amount of moving distance during commutation operation.

Best Regards,

Hi Younhwan

Do you mean the moving distance in the motor initialization?

If not, please explain what do you mean with “commutation operation”.

Kind regards,

I think he means Phasing, also known as phase search:

Thank you for your help.
