The problem of sensor less mode setting failure

Hello everyone, I’m a newcomer
I came across some situations
QQ截图20210129153438 UN2WQNT{%BGVSG85)}WJCQ
odrv0.axis0.requested_state
odrv0.axis0.controller.vel_setpoint
Invalid setting

This is my setup
odrv0.axis0.controller.config.vel_gain = 0.02
odrv0.axis0.controller.config.vel_integrator_gain = 0.05
odrv0.axis0.controller.config.control_mode = 2
odrv0.config.brake_resistance=1
odrv0.axis0.motor.config.motor_type=0
odrv0.axis0.motor.config.pole_pairs = 7
odrv0.axis0.motor.config.current_lim = 20
odrv0.axis0.sensorless_estimator.config.pm_flux_linkage = 5.51328895422 / 700
odrv0.axis0.motor.config.direction = 1
odrv0.axis0.controller.vel_setpoint = 300

odrv0.save_configuration()
odrv0.reboot()

odrv0.axis0.controller.vel_setpoint = 300
odrv0.axis0.requested_state = AXIS_STATE_SENSORLESS_CONTROL
