Hi I used TMDSHVMTRPFCKIT and F28035 with self servo motor.
Hi
I used TMDSHVMTRPFCKIT and F28035 with self servo motor.
It didn't run smooth on HVPM_Sensorless level 2 and level 3 build that run jiggle and nosie.
I didn't clear The servo motor parameters.
But It can run fine with Demo code that flash at F28035(control card ) and HVMTRPFCKIT-GUIv1.
Could you give me The parameters on Demo code ???
How can I make it run smooth ???
How can I make it synchro ???
Regards,
Jimmy
Jimmy,
Level 2 and level 3 builds still perform a forced D-axis angle. The sensorless observer is not being used to find the D-axis angle yet. Once you get to build level 5, the motor should run smoothly.

Hi Erc,
I was still jiggle on level5.
Maybe , I didn't tune fine PID on current loop.
Did I tune PID on lsw=1???
How can I tune it ???
Check pid1_id.Fdb in the watch windows with continuous refresh feature whether or not it should be keeping track pid1_id.Ref for PID_REG3 module. If not, adjust its PID gains properly.Check pid1_iq.Fdb in the watch windows with continuous refresh feature whether or not it should be keeping track pid1_iq.Ref for PID_REG3 module. If not, adjust its PID gains properly.
Level5 - DualTimeA-1 : clarke1.As DualTimeB-1: Smo1.Theta
Did you update the settings for your motor in HVPM_Sensorless-Settings.h?
Are you following the user guide on how to tune the Id, Iq, and Speed PI controllers?

Hi ,
I have tune Id and Iq .
But, when I run on level5 , It auto run revers. You see that the smo1.Theta revers with rg1.Out .
This servo motor can run very well on HVMTRPFCKIT-GUI-FlashImagev1.out .
DualTimeA-3 : smo1.Theta DualTimeB-3 : rg1.Out
I look for DMClib Configuration.
On System Parameters & Requirements (i.e. User inputs) field, I don't known which parameter match with Designed voltage gain constant in switching function , Cut-off frequency of low-pass filter and Deadband requirement for Inverter ???
Does the DMClib Configuration be used on HVMTRPFCKIT-GUI-FlashImagev1.out???
Hi Chris ,
I review my servo motor then tune I loop Ok.
I have a phenomenon. when I enable Realtime Options (Halt the target before any debugger access) on Code Composer Studio , The F28035 responded to Motor control too late .
How can I read data on realtime and DCU work fine ???
