The robot vibrates
because of other
surrounding
equipment in the
working environment
（

）
Resonance occurs when
the robot and peripheral
devices operate
simultaneously;
（

）
The operation of
peripheral devices cause
electromagnetic interference
to the robot.

Check the connection of the
ground wire and ensure it’s effective.
The robot makes
abnormal noise in the
following two
situations:
（

）
Restarting after
a long-term
shutdown
（

）
Start operation
after replacement of
grease.
In the two situations, running
and operation exist in the
early stage of robot’s
operation.
（

If operation in low-speed mode
for 1-2 days does not improve the
noise issue, internal parts may be
damaged. Please consult our

The abnormal external
voltage or electromagnetic
environment interferes with
the movement of the control
cabinet leading to vibration.
