SPINFamily Evaluation Software - BEMF Calculation

Hi,

When I am using the BEMF compensation configuration within the SPINFamily Evaluation Software, I input the Application Parameters and the Motor Parameters for my particular motor. 

 

 

 

When I press the ‘Evaluate’ button at the bottom right of the menu, the following Device Configuration Values are calculated:

KVAL_HOLD

KVAL_ACC

KVAL_DEC

KVAL_RUN

ST_SLP

INT_SPEED

FN_SLP_ACC

FN_SLP_DEC

 

These calculated values can then be written to the device and can be seen in the Phase current control tab within the ‘Device Configuration’ menu.

 

 

 

How are the Device Configuration Values calculated from the values that I have inputted?

Is there a particular calculation that must be used?

 

Kind Regards,

Ernest
