Jog the X Axis 0.010" (0.25 mm) in the positive (+) direction.
Jog the X Axis 0.010" (0.25 mm) in the negative (-) direction.
Record the difference between these two values:
- the indicator value
- the X-Axis position on the control
If the difference is more than 0.0002" (0.005 mm), the backlash is too large.
Caution: Before you do the manual backlash test, make sure the machine is not in an alarm condition: Release [EMERGENCY STOP], and push [RESET] to stop each alarm.
Do a manual test of the backlash as follows:
- With your hands, push on the right side of the table.
- Set the indicator to 0.
- With your hands, push on the left side of the table.
If the indicator shows more than 0.0002" (0.005 mm), the backlash is too large.
