Using the MCF8316AEVM, the motor never gets into closed loop control. Instead, it locks into a random position. This is not braking, but rather maintaining torque at zero speed, thus consuming current.
I followed the steps of the GUI. The communication with the board is okay, demonstrated by the ability to read all 80 registers from the device. I am also able to read the bus voltage and other parameters I select from the algorithm. The two auto read flags are selected, and I see no faults. The open loop operation occurs as expected, with I believe to be the MPET cycle. The motor runs for few seconds and then stops, locking in position as described above.
Questions:
1. Should the transition between open and closed loop occur automatically, with the motor spinning continuously, or is there a step I'm missing between the two modes?
2. Why is the motor locked in place?
3. How can we identify whether the MPET cycle is complete?
4. Once we program the EEPROM, how do we prevent the MPET process to run every time the board is powered up?
Thank you!
