How to customize hardware and software parameters

It is quite easy to set up an operational evaluation platform with a drive system that includes

the STR750-MCKIT (featuring the STR750 microcontroller, where this software runs) and

an AC induction motor.

This section explains how to quickly configure your system and, if necessary, customize the

library accordingly.

Follow these steps to accomplish this task:

Gather all the information that is needed regarding the hardware in use (motor

parameters, power devices features, speed/position sensor parameters, current

sensors transconductance);

Edit, using an IDE, the configuration header file 75x_MCconf.h (as explained in more

detail in Section 2.2.1), and the following parameter header files,

–

MC_Control_Param.h

(see Section 2.2.2),

–

MC_encoder_param.h

(see Section 2.2.3) or MC_tacho_prm.h (see

Section 2.2.4),

–

MC_ACmotor_prm.h

(see Section 2.2.5);

Re-build the project and download it on the STR750 microcontroller.
