6.2.2 Timing Belt Replacement
The timing belt is used in the robot for the driver system of the J2, J3, J5 and J6 -axis. Although
the belt tension has been adjusted before the robot delivery, the timing belt will wear depending on
the working conditions. The belt tension might be lower than the standard after operating for a long
time. The timing belt should be periodically checked, maintained and replaced.
Timing Belt replacement period
When the maintenance time is up to (six month), check the belt tension. If the tension is
insufficient, adjust the belt tension. If the belt is excessively worn (wearing about half of the tooth
width), the belt tooth is cracked or the belt is broken, replace the belt, but you are required to re-origin
the points to correct the points.
When replacing the belt, the robot system origin may deviate.
In this case, the position data must be rechecked if the origin
is offset. Please refer to section 4.1 for Zero-position setting.
