Manipulator Manual of AIR20-A Industrial Robot
Common Faults and Treatment
61
Fault
Classification
Possible Causes
Treatment
Vibration
Abnormal noise
Causes may not be
determined mechanically
1. Fault of the circuit inside
the controller, failure of
command to transmit to
the motor, or the motor
information not correctly
transmitted
to
the
controller
2. Fault of pulse encoder
and the position of motor
not correctly transmitted to
the controller
3. Failure of motor body to
perform
its
original
functions
4. Breakage of internal
motor cable of manipulator
causes the command not
to be correctly transmitted
to the motor and control
system
5. Voltage drop and no
guarantee for the specified
voltage
6.
Incorrect
control
parameters are input
1. For the fault of controller,
see the controller manual
2. Replace the motor of
vibrating Joint to confirm
whether it vibrates
3. Check the cables of the
manipulator body, between
the manipulator body and
control cabinet, and inside
the controller for damage,
and if so, replace the cable.
4. Check whether the cable
joint is in good contact. In
case of the poor contact or
looseness, re-tighten or
take appropriate measures
to ensure the good contact.
5. Check whether the action
control parameters are
correct, and if not, re-enter
the correct parameters.

The
mechanical
action
near
the
manipulator is closely
related to the vibration of
robot.
1. Mechanical electrical
noise from the manipulator
2. If the grounding wire is
not connected properly,
the electrical noise will mix
into the grounding wire,
causing the vibration of
manipulator due to the
interference
with
command
3. Poor connection of
grounding wire will lead to
the unstable grounding,
causing the vibration of
manipulator
due
to
electrical
noise
interference.
1. Connect the grounding
wire properly to avoid the
electrical noise mixed into
the manipulator
2. Please consult with us
