PGA411Q1EVM: Pga411qevm

Part Number: PGA411Q1EVM

hello I use the PGA411Q1EVM

for a project. in encoder mode can a phase shift be created between the mechanical and electrical angle of the motor. I get the u1, v1 and w1 signals on the ord0, ord2 and ord3.

Thank you

Hi,

Does it mean that you want to have a delay when you read the angle information from u1, v1 and w1?

Hi
Yes .
sometimes the motor and the resolver do not have the same angle. I have to compensate electronically.
And aligne the output u ,v and w to the real u ,v and w of the motor.
I can do it mechanically but if it's possible with the board it will be great.
Thank you

Hi,

I dont think we have feature to delay the angle reading from the u,v, and w. Compensating electronically is the best options to these kinds of applications.

I want to make a phase shift between the reading of the resolver

and the U, V and W outputs on DRO0, DRO1 and DRO2

Hi,

Are you reading SPI register to read the resolver angle? I mean, what method are you using to read the resolver?

But, we dont have a mechanism to delay U,V and W outputs.
