In the power-on state, visually check whether the
fan rotates normally and aurally check whether there is any
abnormal noise. In case of any abnormality, find out the
cause and solve the fault.
In the power-on state, connect the upper computer
software ARM to the robot body with network cable for
communication, and test whether the robot can be servoed
and work normally with ARM. If the robot can work
normally, it indicates that the test signals of all fans are
normal. If the robot cannot work properly, find out the cause
and solve the fault. The robot may be servoed to work after
the alarm is cleared, or the cable may be in poor contact, or
the fan is damaged and needs to be replaced.
After power off, turn the fan with hand to test
whether the resistance of the fan is normal. If the resistance
is too large, replace the fan.
Clean the dust on the blades with appropriate
intensity. Wipe the dust off the surface with a clean cloth in
a cyclic manner until it is clean.
