ERROR_INVALID_STATE — 0x00000001
An invalid state was requested.
You tried to run a state before you are allowed to. Typically you tried to run encoder calibration or closed loop control before the motor was calibrated, or you tried to run closed loop control before the encoder was calibrated.
ERROR_DC_BUS_UNDER_VOLTAGE — 0x00000002
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 controller.config.vel_limit and
motor.config.current_lim.
ERROR_DC_BUS_OVER_VOLTAGE — 0x00000004
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.
