TMS320F28069M: Can I build one project whose function covers lab6e + lab11e or lab11d + lab11e for two motors with hall sensors?

Part Number: TMS320F28069M

hello, 

you know  that motor with hall sensors is much cheaper than motor  with encoder. 

so, Can I build one project  whose function covers  lab6e + lab11e or lab11d + lab11e for two motors with hall sensors?

lab6e--Dual Motor Sensorless;--MOTION feature 

lab11d --Dual Motor Sensorless Velocity Control;  --FOC feature

lab11e--Hall sensor start-up with transition to FAST;----FOC feature

anothor question , I am running lab11e，and I find the motor is wandering when the BLDC mode is working at the very low speed.

but I do not know how to solve the problem.

    Instaspin-motion doesn't support hall sensor as lab11e, so you can't combine lab6d/e + lab11e to a project to run one or two-motor with instaspin-motion.

    You can implement the hall sensor control in lab11e to lab11d for two motor.

    The lab11e with hall sensor is just for improving the startup performance, doesn't optimize for low speed. You have to tune the control parameters and implement a higher PWM frequency if you want to run the motor at low speed with a hall sensor.

    Thank you, Quote

    You have to tune the control parameters and implement a higher PWM frequency if you want to run the motor at low speed with a hall sensor.---Can you provide more information? such as example or quantitative analysis paper.

    Please refer to the lab guide that includes all contents we can provide now. You might have to tune the control parameters according to the system and motor you are working on.
