Topic-icon Resolver setup and test not referenced in manual

Hello,

I have a new RGBL1896 which is supposed to run a BLDC-motor which uses a resolver as position feedback.

In the user manual (V1.8 ) I see resolver referenced a couple of times, but the part that describes the resolver calibration seems to be missing. Or are you supposed to use the same calibration sequence as for sin/cos sensor?
I need to know the correct way to calibrate the resolver feedback because as it is now, I don’t know if I am having issues with the resolver wiring or the calibration sequence.

Any help with describing the calibration steps for resolver would be greatly appreciated.

Best Regards,
Niklas

In the current release firmware it performs a calibration step when you switch to sinusoidal.

Can you post the resolver you are trying to use? It may draw too much current - we can only drive ~250mA on our RGBL1860 Resolver Excitation.
