Tooling and additional equipment must be removed before the adjustment
process is started if they are likely to impede the adjustment work.
10.1.1 Measuring the backlash
Preconditions The drive assembly must be freely accessible, and it must be possible to
fasten the dial gauge to the beam.
The following aids are required:
Dial gauge with magnetic stand.
Spring balance with measurement range ≥ 400 N.
Procedure 1. Fasten the dial gauge (>>> Fig. 10-3) to the beam so that the probe is in
contact with the carriage.
2. Attach a spring balance at a suitable point on the carriage.
3. Pull the carriage with a force of 400 N (spring balance) in the plus direction.
4. Set the dial gauge to zero while maintaining the force.
5. Pull the carriage with a force of 400 N (spring balance) in the minus direc-
tion.
6. Read the measured value.
7. If the measured value is outside the range from 0.2 mm to 0.24 mm, the
backlash must be adjusted as shown in (>>> 10.1.2 "Adjusting the back-
lash" page 71).
8. If the measured value is within the range from 0.2 mm to 0.24 mm, the
backlash is correct.
9. Remove the measuring set-up.
Warning!
Unintentional motions of the linear unit, the robot and affected system com-
ponents can cause injuries and damage to property. If work is carried out on
an operational linear unit, the linear unit, the robot and affected system com-
ponents must be secured by activating the EMERGENCY STOP button.
Warn all persons concerned before putting it back into operation.
