Used belt is the one having been installed and used for more than 12 hours.
Compared with the new timing belt, the force value decreases 15% and the frequency value
decreases 28% when the timing belt has been installed and used for more than 12 hours but less
than 150 hours. When the timing belt has been installed and used for more than 150 hours, both
the force and frequency values decrease 30%.
The value range is only for reference.
Action
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the robot
working area.
Gain access to each timing belt by removing
the cover.
Check the timing belts for damage or wear.
Check the timing belt pulleys for damage.
If any damage or wear is detected, the part
