block diagram of 7344 controller

[jimmyjimmy2000]

Hi,
Before building up my system, I'd like to simulate the control system model with Matlab. But I cannot know the 7344's system block diagram in detail. Can you provide the whole working block diagram of 7344 include position loop and velocity loop. And by the way, I want to know how the vff ,aff and vbf works in 7344 control loop. Thanks.

Jimmy,

I attached a block diagram of the PID control loop, that is what we are allow to give out, the motion board ends after the Kdac block.

The control loop of the 7344 is well explained in the document called: Understanding Servo Tune here in the Developers Zone, please check it out, the gains you are looking for are explained at the bottom of it.

Good luck!
