Using NXP S12Z MagniV, we are rotating a 3 phase BLDC motor.
We are using "Current Sense Amplifier and Overcurrent Comparator" in the GDU.
The GDU is driven by PWM from the PMF module.
Present implementation -
When over current situation occurs, the OC comparator trips and cause the GDU output to be OFF.
Since this point, the motor stops permanently till the MCU reset.
Requested modification -
When the OC comparator trips and cause the GDU to be OFF, is there a way to clear this trip condition using software such that the PWM output from the GDU can be re-started ?
If yes, what is the procedure/settings for this ?
