TMS320F28054M: 3 phases Linear motor sensored inertia ID

Part Number: TMS320F28054M

Hi Ti.

I am working on a linear motor control and got stuck on the INSTASPIN lab12a. The motor doesn't move during the inertia ID and keep generate error ID 2003,2004 AND 2006.

I double checked the phases ABC and encoder AB wiring, and also did all other wiring combination test. Still no improvements or fix. 

The linear motor works well with Torque/current loop control, speed loop control. Not very stable through MOTION-Lab6a.b,c, but it can run the plan.

If I can control this linear motor through the previous labs(lab1-11), does this mean that I can 100% control this linear motor with MOTION position loop(lab12-13)?

    Not sure, we didn't test the instaSPIN-motion on any linear motor by now. It seems like the connection order of the motor wires or encoder wires is not right. Please make sure both the motor and encoder wires are connected properly and set the encoder lines correctly as well.
