Troubleshooting Chapter 9
Evaluate the Direct Drive Linear Stage
1. Power down the drive system.
2. Disconnect the drive from the linear stage.
3. By hand move the carriage through the entire range of motion. It should
move free and smooth.
4. If excessive resistance is felt, clean and relubricate the linear bearings.
5. Perform the procedures for a direct drive linear stage listed in the
troubleshooting tables on
page 78 .
6. If the problem persists, return for factory evaluation and possible repair.
Evaluate the Ball Screw Linear Stage
1. Power down the drive system.
2. Disconnect the drive from the linear stage.
3. Remove the rotary motor.
4. By hand move the carriage through the entire range of motion. It should
move free and smooth.
ATTENTION: Lockout and tagout input power before servicing
the linear stage.

TIP To make it easier to move a fine pitch stage, connect an
11 mm (0.44 mm) extension rod to the motor coupling. Move
the stage by turning the extension with a hand wrench.

Before disconnecting,
mark the current position
on the motor shaft.
