We are using a NEO on our climber. While testing, the breaker supplying power to the NEO tripped. At this point the NEO would not work. I wasn’t present at the time but I’m told the light on the Spark Max was blinking indicating that it didn’t have 12V power. USB wasn’t connected and 12V power was the only power supply present to the Spark Max. We power cycled the motor controller and it started working again.
Has anyone else encountered something like this?
We were/are considering swapping our CIMs out for NEOs on our swerve at our first event but if they aren’t robust against intermittent power drops then this would be a show stopper.
Our theory is that an internal cap is keeping the Spark Max alive while the breaker is tripping but the software state becomes invalid during this time. By killing power for a longer duration this forces a hard reset of the Spark Max.
