Repairing After Collisions

Overview

Components of the axis may be damaged or destroyed as a result of a collision.

NOTE: After a collision, inspect the mechanical drive elements, the linear guide, and the elastomer coupling for damage according to the instructions in the following sections.

WARNING

FALLING OR EJECTED PARTS

oThoroughly inspect all components of the axis and all components attached to the axis, including the motor and the gearbox, for damage after a collision.

oDo not use the axis if any of the components are damaged or suspected to be damaged.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Verifying the Components

Step	Action
1	Verify components for completeness. If any components are missing, locate the same and remove them from the surrounding machinery.
2	Replace damaged or missing components.

Verifying the Toothed Belt

Step	Action
1	Verify the toothed belt by a visual inspection for damaged teeth and abrasion. To perform a visual inspection, maybe it is necessary to remove the toothed belt.

NOTE: A damaged toothed belt must be replaced. For detailed information, refer to Replacing the Toothed Belt.

Verifying the Linear Guide

Step	Action
1	Inspect the carriage for backlash. If the carriage has backlash, the preload has been modified or the linear guide is worn out. For further information, contact your local Schneider Electric service representative.
2	Remove the toothed belt.
3	Verify the roller guide or recirculating ball bearing guide by a visual inspection for damage.
4	Manually move the carriage (without toothed belt) and inspect for irregular noise or vibration. Irregular noise or vibration indicates a deformation in the linear guide. Deformation causes rapid wear.

NOTE: Damaged parts of the linear guide must be replaced. Contact your local Schneider Electric service representative.

Verifying the Elastomer Coupling (Optional Equipment)

Step	Action
1	Remove the motor and/or the gearbox as described in Replacing the Motor and Gearbox.
2	Verify the elastomer coupling by a visual inspection for damage.

NOTE: A damaged elastomer coupling must be replaced. For detailed information, refer to Replacing the Elastomer Coupling.

Verifying the Cover Strip (Optional Equipment)

Step	Action
1	Verify the cover strip by a visual inspection for damage.

NOTE: A damaged cover strip must be replaced. For detailed information, refer to Replacing the Cover Strip.
