Separate logic and HV DC powers

Is it possible to provide external 5 V voltage source for the ODrive so that the MCU and encoders stay powered on and running while HV DC is disconnected?

We need some way to assure safe operation and we will have multi step E-stop

  • software based stop commanded
  • HV DC bus disconnect (after short delay)

It would be great if recovery from HV DC bus disconnect would not require the encoders to be recalibrated and the axis re-homed/referenced before continuing.

Yes. You can apply 5V to the programming header.
