Use S12ZVML-MINIBRD to control the motor, use FreeMASTER to control motor speed, Can FreeMASTER change the current limit ? FreeMASTER current can only be transferred to 10A.
I assume you use Complete BLDC motor control application software package for S12ZVML-MINIBRD board.:
When you compile the demo and flash it to the miniboard connected with BLDC motor you can start to run the motor from the FreeMaster project and actually you can set DC bus current limit in case the DC bus current that is being filtered and measured can potentially extend this limit. In such case the speed of the motor will be slowed down to prevent any high current.
