Errors

Blink Codes #

LV Side #

Normal Operation #

  • No Error (Green LED on top illuminated. Good!)
  • Drive disabled (Yellow LED on top. Drive ready to go but disabled.)
  • Autophasing (Green and Yellow)

Errors #

  • Soft fault, resettable (Red LED blinks according to the list below)
  • Hard fault, bad! (All LEDs on top blink.)

Count the number of blinks of the red LED. Each number indicates a different class of faults.

LED Blink TimesErrorPossible Solution
1Command ErrorCommon during setup. Only really relevant to smart-serial
2Motor Feedback ErrorVerify motor feedback connections.
3Commutation Feedback ErrorCheck commutation feedback connections and configuration.
4Joint Feedback ErrorEnsure joint feedback is properly connected and configured.
5Position ErrorReview positioning mechanisms and settings.
6Saturation ErrorAdjust parameters to avoid saturation.
7Motor temperature highCheck for overheating issues or motor ptc misconfiguration.
8HV Side serial CRC ErrorEnsure data integrity during communication with the side.
9HV Side comms Timeout ErrorHV side is not powered or programmed correctly.
10HV Side over-temperatureCheck the fan, air intake/output obstruction or dust in the heatsink.
11HV Voltage out of rangeCheck if power supply is stable and if the dynamic braking circuit is working.
12HV Side FaultInvestigate specific faults reported by the HV side.
13HV current offset faultDamaged F3 micro ADC?
14HV Overcurrent RMSReduce average current consumption to stay within limits.
15HV Overcurrent PeakLimit peak current spikes to prevent overcurrent issues.
16HV Overcurrent HWThe motor power size is too high (or the bridge is broken)

HV Side #

Normal operation #

  • Green LED at power input

Errors #

  • Red LED blinks fast - Bootloader but no or broken firmware
  • Red LED blinks slow - No communication with F4
  • Red LED does not blink AND F4 not plugged in - No firmware or bootloader
