Fault
Fault classification
Possible cause
Solution
Drop of manipulator
axis
◼
The brake fails completely and
the axis drops quickly
◼
The axis slowly drops after the
brake is locked
1.It may be because the brake
drive relay is damaged, and the
brake is always in the energized
status, having no braking effect.
2.It may be because the braking
effect is reduced due to wear to
the brake and damage to the brake
body
3.It may be because the
lubricating oil and grease enter the
motor, which causes the brake
slipping
1.Check whether the brake drive
relay is damaged, and if yes,
replace it
2.If the brake is worn, the brake
body is damaged, or the grease
has entered the motor, replace it.
3.Please contact the company
Position offset
◼
The
manipulator
motion
deviates from the teaching
position
◼
The
manipulator
’
s
repositioning accuracy is greater
than the allowable value
Mechanical fault:
1.If the repositioning accuracy is
unstable, it may be caused by the
failure of the mechanical system,
loose screws, etc.
2.After certain deviation, the
repositioning accuracy is stable. It
may be because the base surface
and the joint surface between the
castings of the axes and the
reducer slide due to excessive
loads such as collision.
3.It may be because the motor
encoder is faulty
1.When
the
repositioning
accuracy is unstable, please refer
to the vibration, abnormal noise
and shaking items to eliminate the
mechanical fault
2.When
the
repositioning
accuracy is stable, please modify
the teaching program. If the
collision no longer occurs, there
will be no position offset.
3.If the motor encoder is faulty,
please replace the motor or
encoder
4.Please contact the company
◼
The position offset is only
involved with specific peripheral
equipments
Position offset of peripheral
equipment:
1.It may be because the peripheral
equipment is subjected to external
forces, which causes it to be offset
from the manipulator.
1.Please change the position of
the peripheral equipments
2.Please modify the teaching
program
3.Please contact the company
◼
The position offset occurs after
changing the parameters
Parameters:
1.It may be because the origin of
the manipulator is lost due to
modification of the calibration
data
1.Re-enter the previously correct
calibration data
2.In case of uncertain calibration
data, please recalibrate the
manipulator
3.Please contact the company
