--- title: Errors slug: legacy-doc-gk2/errors icon: 🚨 createdAt: 2024-01-15T00:51:43.384Z --- Details about the detection and handling of errors on the micro**DRIVE** units. The micro**DRIVE** units datalog two separate error sectors. The two bitfields and the details of each entry can be found below. The bits are set when the described event occurs. ## Error 1 :::hint{type="info"} Bit meaning of the Error 1 field logged internally on micro**DRIVE **units. Error bit number matches CAN error code. ::: | **Error Bit** | **Name** | **Description** | | ------------- | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | 0 | Internal Error - Firmware | Internal error - contact us for assistance. | | 1 | Internal Error - Firmware | Internal error - contact us for assistance. | | 2 | Configuration Corrupt | The loaded configuration was corrupted on the unit. Connect to the configuration tool for reset. Unable to internally reset to defaults. The motor drive is disabled. | | 3 | Configuration Reset | The loaded configuration was reset to defaults. The configuration was corrupt. Successfully reset to defaults. | | 4 | Power Supply Fault 1 | An onboard power supply for the logic circuit faulted. Likely a hardware issue. Contact us for further details. | | 5 | Power Supply Fault 2 | An onboard power supply for the logic circuit faulted. Likely a hardware issue. Contact us for further details. | | 6 | Bridge Test Fault | The bridge test returned a negative result, indicating hardware or motor damage. Inspect or replace the unit. | | 7 | Over Voltage Fault | The bus voltage exceeded the unit maximum. The motor drive was shut down and will resume once the event clears. | | 8 | Under Voltage Fault | The bus voltage dropped below the unit minimum. The motor drive was shut down and will resume once the event clears. | | 9 | Over Config Voltage Fault | The bus voltage exceeded the configured maximum. The motor drive was shut down and will resume once the event clears. | | 10 | Under Config Voltage Fault | The bus voltage dropped below the configured minimum. The motor drive was shut down and will resume once the event clears. | | 11 | Absolute Over Temp Fault | The unit reached its absolute maximum over temperature limit (135 degrees C), and the motor drive was temporarily disabled. The event will clear after the temperature drops. | | 12 | Internal Error - Hardware | Internal error - contact us for assistance. | | 13 | Internal Error - Hardware | Internal error - contact us for assistance. | | 14 | Signal Input Lost | The loss of a valid signal input configured period will stop the motor drive output. The drive will resume when the signal is returned, and the throttle is 0%. The throttle 0% setpoint requirement can be overwritten when using CAN Bus signalling. | | 15 | Internal Error - Hardware | Internal error - contact us for assistance. | | 16 | Bootloader Reported Fault | The bootloader reported a fault with either firmware or recovery sections. Likely an update has failed or a hardware fault has occurred. | ## Error 2 :::hint{type="info"} Currently unused, reserved for future use. :::
