Other Parts Discussed in Thread: SYSCONFIG
Team,
My customer is working on motor control design using F280041C, and he has questions:
I downloaded and Installed TI System Configuration Tool that let me configure the micro’s pins. I attached the file. There are couple things I would like Piccolo and Motor Control teams to give me OK for.
- I was reading Reference Manual for the microcontroller. I am not familiar how EPWM modules are utilized by motor control software but I assume three of them have to be synchronized. The information on pages 1825 and 1892 tells me that if I use EPWM modules 1, 2, and 3 I’ll be OK. The problem I have with that is PCB layout (one last pin is on the other corner). Can I utilize EPWM modules 1, 2, and 4?
- Please check analog signals assignment. I assigned three motor phase current to channel 1 on three ADCs respectively. I assigned three BEMF signals to channel 2 on three ADCs respectively. Is this OK for motor operation? Are there any restrictions where Battery Voltage and Temperature signal can be? I will not use PGAs. I will use only ADCs since a gate driver chip will amplify phase current signals.
- Please check if I did anything wrong for motor control operation.
Note e2e will not allow me to attach the syscfg file, please let me know whom I can email it to?
Thanks
