Warnings

details about the detection and handling of warnings on the micro drive units the micro drive units datalog two separate warning sectors the two bitfields and the details of each entry can be found below the bits are set when the described event occurs warning 1 bit meaning of the warning 1 field logged internally on micro drive units warning bit name description 0 motor started motor is running 1 motor saturated the esc detected a motor saturation and started reducing the output drive (foldback) for a period of time 2 esc over temperature limit the temperature on the esc exceeded the configured temperature limit 3 bus over voltage config limit the bus voltage crossed over the configured voltage limit 4 bus under voltage config limit the bus voltage crossed under the configured voltage limit 5 bridge tests failed the start up bridge tests failed, indicating a hardware failure or motor short the unit should be inspected or replaced 6 bus over voltage absolute limit the bus voltage crossed above the absolute limits of the hardware, resulting in a hard shutdown 7 bus under voltage absolute limit the bus voltage crossed below the absolute limits of the hardware, resulting in a hard shutdown 8 bus voltage maximum ripple the unit requires extra capacitors on the bus or repairs if in service for some time (capacitors worn out) 9 firmware updated the firmware was successfully updated within the last boot up of the unit 10 firmware corrupt an error in the firmware section was detected last boot and successfully repaired indicates possible firmware update failure, or less likely, a memory fault 11 back up corrupt an error in the back up/recovery section was detected last boot and successfully repaired indicates possible firmware update failure, or less likely, a memory fault 12 can bus off occurred a bus off error was reported from the can system it may indicate a hardware fault is present 13 motor sense error the motor temperature sensor has experienced an error, typically indicating a hardware fault 14 afw engaged afw is currently engaged no warning action is necessary useful for debugging purposes 15 not using calibration factory calibrated values are currently not in use, measurements will have an error 16 watchdog fired hardware watchdog has been fired and the unit has reboot serious fault, contact hargrave 17 can out of memory the can handler has run out of memory the bus could be overloaded/not responding 18 motor parked motor is parked when using prop parking warning 2 currently unused, reserved for future use
