Troubleshooting and Test Functions 3
6
Check the tension of the belts.
For this use the Torque2.mac and measure the torque for each axis.
7 Exchange the gripper arm assembly (part number G1313-60010).
8 Adjust the belt tension.
• If the measured torque value is too low, the belt needs to be tightened.
• If the measured torque value is too high, the belt needs to be loosened.
For this, slide the motor (X or theta) on the holder bracket in the
appropriate direction and test the tension with the
torque2
macro. Repeat
this steps until the values are in the appropriate torque range.
9
Exchange the sample transport assembly (G1329-60009).
10
Exchange the main board (part number G1329-69520).
Table 13
Typical ranges Theta (both) 30-50
X-axis (both) 50-90
Z-axis (both) 90-130
Gripper open 30-65
Gripper closed maximum 30

If the Gripper open/closed torque is not in the range, proceed with STEP 7. If the theta or X
torque is not in the range, proceed with STEP 8 (if you think you can adjust the torque),
otherwise proceed with STEP 9.
