error: Property[ODrive.Error]
vbus_voltage: Float32Property

Voltage on the DC bus as measured by the ODrive.

ibus: Float32Property

Current on the DC bus as calculated by the ODrive.

A positive value means that the ODrive is consuming power from the power supply, a negative value means that the ODrive is sourcing power to the power supply.

This value is equal to the sum of the motor currents and the brake resistor currents. The motor currents are measured, the brake resistor current is calculated based on config.brake_resistance.

ibus_report_filter_k: Float32Property

Filter gain for the reported ibus. Set to a value below 1.0 to get a smoother line when plotting ibus. Set to 1.0 to disable. This filter is only applied to the reported value and not for internal calculations.

task_times: ODrive.TaskTimes
system_stats: ODrive.SystemStats
user_config_loaded: Uint32Property
misconfigured: BoolProperty

If this property is true, something is bad in the configuration. The ODrive can still be used in this state but the user should investigate which setting is problematic. This variable does not cover all misconfigurations.

Possible causes:
  • A GPIO was set to a mode that it doesn’t support

  • A GPIO was set to a mode for which the corresponding feature was not enabled. Example: GPIO_MODE_UART_A was used without enabling config.enable_uart_a.

  • A feature was enabled which is not supported on this hardware. Example: config.enable_uart_c set to true on ODrive v3.x.

  • A GPIO was used as an interrupt input for two internal components or two GPIOs that are mutually exclusive in their interrupt capability were both used as interrupt input. Example: Axis:config.step_gpio_pin of both axes were set to the same GPIO.

oscilloscope: ODrive.Oscilloscope
can: ODrive.Can
test_property: Uint32Property
otp_valid: BoolProperty
class ODrive.Error

At least one control iteration was missed.

The main control loop is supposed to runs at a fixed frequency. If the device is computationally overloaded (e.g. too many active components) it’s possible that one or more control iterations are skipped.


The DC voltage fell below the limit configured in config.dc_bus_undervoltage_trip_level.

Confirm that your power leads are connected securely. For initial testing a 12V PSU which can supply a couple of amps should be sufficient while the use of low current ‘wall wart’ plug packs may lead to inconsistent behaviour and is not recommended.

You can monitor your PSU voltage using liveplotter in odrivetool by entering start_liveplotter(lambda: [odrv0.vbus_voltage]). If you see your votlage drop below config.dc_bus_undervoltage_trip_level (default: ~ 8V) then you will trip this error. Even a relatively small motor can draw multiple kW momentary and so unless you have a very large PSU or are running of a battery you may encounter this error when executing high speed movements with a high current limit. To limit your PSU power draw you can limit your motor current and/or velocity limit Axis:controller.config.vel_limit and Axis:motor.config.current_lim.


The DC voltage exceeded the limit configured in config.dc_bus_overvoltage_trip_level.

Confirm that you have a brake resistor of the correct value connected securely and that config.brake_resistance is set to the value of your brake resistor.

You can monitor your PSU voltage using liveplotter in odrivetool by entering start_liveplotter(lambda: [odrv0.vbus_voltage]). If during a move you see the voltage rise above your PSU’s nominal set voltage then you have your brake resistance set too low. This may happen if you are using long wires or small gauge wires to connect your brake resistor to your odrive which will added extra resistance. This extra resistance needs to be accounted for to prevent this voltage spike. If you have checked all your connections you can also try increasing your brake resistance by ~ 0.01 ohm at a time to a maximum of 0.05 greater than your brake resistor value.


Current flowing back into the power supply exceeded config.dc_max_negative_current. This can happen if your brake resistor is disabled or unable to handle the braking current.

Check that config.enable_brake_resistor is True and that (V_power_supply / Brake_resistance) > (total motor.config.current_lim + total motor.config.current_lim_margin).


Too much current was pulled from the power supply. ibus exceeded config.dc_max_positive_current.


config.brake_resistance is non-positive or NaN. Make sure that config.brake_resistance is a positive number.

You also need to set the corresponding GPIOs to GPIO_MODE_UART_A. Refer to [interfaces](interfaces.md) to see which pins support UART_A. Changing this requires a reboot.

enable_uart_b: BoolProperty

Enables/disables UART_B.

You also need to set the corresponding GPIOs to GPIO_MODE_UART_B. Refer to [interfaces](interfaces.md) to see which pins support UART_B. Changing this requires a reboot.

uart_b_baudrate: Uint32Property

Defines the baudrate used on the UART interface.

See uart_a_baudrate for details.

uart_c_baudrate: Uint32Property

Not supported on ODrive v3.x.

enable_can_a: BoolProperty

Enables CAN. Changing this setting requires a reboot.

enable_i2c_a: BoolProperty

Enables I2C. The I2C pins on ODrive v3.x are in conflict with CAN. This setting has no effect if enable_can_a is also true. This setting has no effect on ODrive v3.2 or earlier. Changing this setting requires a reboot.

usb_cdc_protocol: Property[ODrive.StreamProtocolType]

The protocol that’s being run on the device’s virtual COM port on USB. Note that the ODrive has two independent interfaces on USB: One is the virtual COM port (affected by this option) and the other one is a vendor specific interface which always runs Fibre. So changing this option does not affect the working of odrivetool.

uart0_protocol: Property[ODrive.StreamProtocolType]
uart1_protocol: Property[ODrive.StreamProtocolType]
uart2_protocol: Property[ODrive.StreamProtocolType]
max_regen_current: Float32Property

The bus current allowed to flow back to the power supply before the brake resistor module will start shunting current.

brake_resistance: Float32Property

Value of the brake resistor connected to the ODrive.

If you set this to a lower value than the true brake resistance then the ODrive will not meed the max_regen_current constraint during braking, that is it will sink more than max_regen_current into the power supply. Some power supplies don’t like this.

If you set this to a higher value than the true brake resistance then the ODrive will unnecessarily burn more power than required during braking.

enable_brake_resistor: BoolProperty

Enable/disable the use of a brake resistor.

Setting this to False even though a brake resistor is connected is harmless. Setting this to True even though no brake resistor is connected can break the power supply. Changes to this value require a reboot to take effect.

dc_bus_undervoltage_trip_level: Float32Property

Minimum voltage below which the motor stops operating.

dc_bus_overvoltage_trip_level: Float32Property

Maximum voltage above which the motor stops operating.

This protects against cases in which the power supply fails to dissipate the brake power if the brake resistor is disabled. The default is 26V for the 24V board version and 52V for the 48V board version.

enable_dc_bus_overvoltage_ramp: BoolProperty

Enables the DC bus overvoltage ramp feature.

If enabled, if the measured DC voltage exceeds dc_bus_overvoltage_ramp_start, the ODrive will sink more power than usual into the the brake resistor in an attempt to bring the voltage down again.

The brake duty cycle is increased by the following amount:

  • ODrive:vbus_voltage == dc_bus_overvoltage_ramp_start => brake_duty_cycle += 0%

  • ODrive:vbus_voltage == dc_bus_overvoltage_ramp_end => brake_duty_cycle += 100%

  • This feature is active even when all motors are disarmed.

  • This feature is disabled if brake_resistance is non-positive.

dc_bus_overvoltage_ramp_start: Float32Property

See enable_dc_bus_overvoltage_ramp.

Do not set this lower than your usual ODrive:vbus_voltage, unless you like fried brake resistors.

dc_bus_overvoltage_ramp_end: Float32Property

See enable_dc_bus_overvoltage_ramp.

Must be larger than dc_bus_overvoltage_ramp_start, otherwise the ramp feature is disabled.

dc_max_positive_current: Float32Property

Max current the power supply can source.

dc_max_negative_current: Float32Property

Max current the power supply can sink.

You most likely want a non-positive value here. Set to -INFINITY to disable. Note: This should be greater in magnitude than max_regen_current

will fall through to idle

IDLE = 1 (0x1)

Disable motor PWM and do nothing.


Run the startup procedure.

the actual sequence is defined by the config.startup… flags


Run motor calibration and then encoder offset calibration (or encoder index search if <axis>.encoder.config.use_index is True).


Measure phase resistance and phase inductance of the motor.

  • To store the results set motor.config.pre_calibrated to True

and save the configuration (save_configuration()). After that you don’t have to run the motor calibration on the next start up. * This modifies the variables motor.config.phase_resistance and motor.config.phase_inductance.

Turn the motor in one direction until the encoder index is traversed.

This state can only be entered if encoder.config.use_index is True.


Turn the motor in one direction for a few seconds and then back to measure the offset between the encoder position and the electrical phase.

  • Can only be entered if the motor is calibrated (motor.is_calibrated).

  • A successful encoder calibration will make the encoder.is_ready

go to true.


Run closed loop control.

  • The action depends on the controller.config.control_mode.

  • Can only be entered if the motor is calibrated

(motor.is_calibrated) and the encoder is ready (encoder.is_ready).

LOCKIN_SPIN = 9 (0x9)

Run lockin spin.

Can only be entered if the motor is calibrated (motor.is_calibrated) or the motor direction is unspecified (encoder.config.direction == 1)


Run encoder direction search.

Can only be entered if the motor is calibrated (motor.is_calibrated).

HOMING = 11 (0xB)

Endstops must be enabled to use this feature.


Rotate the motor in lockin and calibrate hall polarity

ODrive assumes 120 degree electrical hall spacing. This routine determines if that is the case and sets the polarity if the halls are on 60 degree electrical spacing

class ODrive.Motor.Error

The measured motor phase resistance is outside of the plausible range.

During calibration the motor resistance and [inductance](https://en.wikipedia.org/wiki/Inductance) is measured. If the measured motor resistance or inductance falls outside a set range this error will be returned. Check that all motor leads are connected securely.

The measured values can be viewed using odrivetool as is shown below: ``` In [2]: odrv0.axis0.motor.config.phase_inductance Out[2]: 1.408751450071577e-05

In [3]: odrv0.axis0.motor.config.phase_resistance Out[3]: 0.029788672924041748 ``` Some motors will have a considerably different phase resistance and inductance than this. For example, gimbal motors, some small motors (e.g. < 10A peak current). If you think this applies to you try increasing config.resistance_calib_max_voltage from its default value of 1 using odrivetool and repeat the motor calibration process. If your motor has a small peak current draw (e.g. < 20A) you can also try decreasing config.calibration_current from its default value of 10A.

In general, you need `text resistance_calib_max_voltage > calibration_current * phase_resistance resistance_calib_max_voltage < 0.5 * vbus_voltage `


The measured motor phase inductance is outside of the plausible range.


DRV_FAULT = 8 (0x8)

The gate driver chip reported an error.

The ODrive v3.4 is known to have a hardware issue whereby the motors would stop operating when applying high currents to M0. The reported error of both motors in this case is ERROR_DRV_FAULT.

The conjecture is that the high switching current creates large ripples in the power supply of the DRV8301 gate driver chips, thus tripping its under-voltage fault detection.

To resolve this issue you can limit the M0 current to 40A. The lowest current at which the DRV fault was observed is 45A on one test motor and 50A on another test motor. Refer to [this post](https://discourse.odriverobotics.com/t/drv-fault-on-odrive-v3-4/558) for instructions for a hardware fix.


The bus voltage was insufficent to push the requested current through the motor. If you are getting this during motor calibration, make sure that config.resistance_calib_max_voltage is no more than half your bus voltage.

For gimbal motors, it is recommended to set the config.calibration_current and config.current_lim to half your bus voltage, or less.


The current sense circuit saturated the current sense amplifier. This can be caused by setting config.current_lim higher than config.requested_current_range. If this happens, increase the requested current range, save the configuration, and reboot the controller.


The motor current exceeded motor.config.current_lim + motor.config.current_lim_margin. The current controller is a PI controller, so it can experience overshoot. The PI gains are automatically calculated based on config.current_control_bandwidth and the motor resistance and inductance (pole placement). Some overshoot is normal, so a sensible solution is to increase the current limit margin if your current limit is large.

CONTROLLER_FAILED = 2097152 (0x200000)

The motor was disarmed because the underlying controller failed. Usually this is the FOC controller.

I_BUS_OUT_OF_RANGE = 4194304 (0x400000)

BRAKE_RESISTOR_DISARMED = 8388608 (0x800000)

An attempt was made to run the motor PWM while the brake resistor was configured as enabled (config.enable_brake_resistor) but disarmed.

The most common cause is that you just set config.enable_brake_resistor to True but didn’t arm the brake resistor yet (by either rebooting or running odrvX.clear_errors()).

Otherwise, the brake resistor can be disarmed due to various system-wide errors. The root cause will usually show up under system when you run dump_errors(odrvX).

To re-arm the brake resistor reboot the ODrive or run odrvX.clear_errors().

SYSTEM_LEVEL = 16777216 (0x1000000)

The motor had to be disarmed because of a system level error. See ODrive:error for more details.

I_leak_max: Float32Property

In almost all scenarios, the currents on phase A, B and C should add up to zero. A small amount of measurement noise is expected. However if the sum of A, B, C currents exceeds this configuration value, the motor gets disarmed immediately.

OVERSPEED = 1 (0x1)

Motor speed exceeded config.vel_limit * config.vel_limit_tolerance and config.enable_overspeed_error was enabled.

Try increasing config.vel_limit. The default of 2 turns per second gives a motor speed of only 120 RPM. Note: Even if you do not command your motor to exceed config.vel_limit, sudden changes in the load placed on a motor may cause this speed to be temporarily exceeded, resulting in this error.

You can also try increasing config.vel_limit_tolerance. The default value of 1.2 means it will only allow a 20% violation of the speed limit. You can set config.enable_overspeed_error to False to disable this error.


The config.input_mode setting was set to an invalid value. See InputMode for available values

Input modes and control modes are separate concepts. A control mode sets the type of control to be used, like position, velocity, or torque control. Input modes modify the input given (input_pos, etc) to give desired behavior. For example, in position control mode, the position filter input mode will smooth out input_pos commands to give smoother motion.


motor.config.bandwidth was set too high to create a stable controller.


An invalid axis_to_mirror was selected


An invalid load_encoder_axis was selected


Indicates the encoder estimation module declined to output a linear position or velocity value and the exception was caught.


Indicates the encoder estimation module declined to output a circular position value and the exception was caught.


The motor mechanical power and electrical power do not agree. This is usually caused by a slipping encoder or incorrect encoder offset calibration. Check that your encoder is not slipping on the motor. If using an Index pin, check that you are not getting false index pulses caused by noise. This can happen if you are using unshielded cable for the encoder signals.

class ODrive.Encoder.Error

Confirm you have entered the correct count per rotation (CPR) for [your encoder](https://docs.odriverobotics.com/encoders). The ODrive uses your supplied value for the motor pole pairs to measure the CPR. So you should also double check this value.

If you are still having issues, you can try to increase config.calib_scan_distance up to a factor of 4 above the default.

If your encoder cpr and motor pole pair settings are correct, this error can be caused because motor cogging makes the motor move less or more than commanded. You can fix this by increasing config.calib_scan_distance.

Note that the AMT encoders are configurable using the micro- switches on the encoder PCB and so you may need to check that these are in the right positions. If your encoder lists its pulse per rotation (PPR) multiply that number by four to get CPR.

NO_RESPONSE = 4 (0x4)

Confirm that your encoder is plugged into the right pins on the ODrive board.


Hall effect encoder only have 6 valid states out of 8 (2^3) possible states. An invalid state can be caused by noise or a hardware fault. If you get this error and you are sure that your electrical connections are correct, add 22nF capacitors between the encoder A,B,Z pins and ground to filter out noise.


Check that your encoder is a model that has an index pulse. If your encoder does not have a wire connected to pin Z on your ODrive then it does not output an index pulse.
