I am new to BLDC motor with the Odrive .
I am using this : NEPTUNE PRO 8020 100KV
Hardware Used :
- Bench power supply : 48v 5A
- Motor driver : Odrive pro (firmware v0.6.7)
- motor Kv : 100Kv
- motor website : NEPTUNE PRO 8020 100KV
here are my parameters(copied from step 2 pyhton conmmand advance user ) :
odrv = odrv0
odrv.config.dc_bus_overvoltage_trip_level = 50
odrv.config.dc_bus_undervoltage_trip_level = 46
odrv.config.dc_max_positive_current = 5
odrv.config.dc_max_negative_current = -1
odrv.axis0.config.motor.motor_type = MotorType.HIGH_CURRENT
odrv.axis0.config.motor.torque_constant = 0.0827
odrv.axis0.config.motor.pole_pairs = 18
odrv.axis0.config.motor.current_soft_max = 10
odrv.axis0.config.motor.current_hard_max = 18
odrv.axis0.config.motor.calibration_current = 4
odrv.axis0.config.motor.resistance_calib_max_voltage = 47
odrv.axis0.config.calibration_lockin.current = 4
odrv.axis0.controller.config.input_mode = InputMode.PASSTHROUGH
odrv.axis0.controller.config.control_mode = ControlMode.TORQUE_CONTROL
odrv.axis0.controller.config.vel_limit = 10
odrv.axis0.controller.config.vel_limit_tolerance = 1.2
odrv.axis0.config.torque_soft_min = -0.1654
odrv.axis0.config.torque_soft_max = 0.1654
odrv.axis0.config.load_encoder = EncoderId.ONBOARD_ENCODER0
odrv.axis0.config.commutation_encoder = EncoderId.ONBOARD_ENCODER0
Please let me know if put any wrong parameter above.
While doing the calibration I am getting the following error.
PHASE_INDUCTANCE_OUT_OF_RANGE and PHASE_RESISTANCE_OUT_OF_RANGE
Connected to ODrive Pro 3466367C3330 (firmware v0.6.7) as odrv0
In [1]: odrv0.axis0.config.motor.phase_inductance
Out[1]: 0.0
In [2]: odrv0.axis0.config.motor.phase_resistance
Out[2]: 0.06416109949350357
Please tell me if i am missing something.
Thanks for the help.
