Cause: There's debris on the ball screw.
Probability How-To Steps Need More?
Low
Clean the ball screw.
Debris on the ball screws can rapidly
accelerate wear and reduce the
lifespan of your machine. Evaluate if
additional measures are required to
protect your machine's ball screws and
ways (like supplemental dust
collection).
Cause: There's a thermal trip or an electrical short on an axis driver.
Probability How-To Steps
Low
1. Examine the LEDs on the axis drivers.
If there's a red LED on the driver, that means it's tripped.
2. Power the machine on and off, and the trip should reset.
3. If the problem continues, examine the wiring for shorts and test the motor resistance. (For more information, see
"There's a defective motor or motor connection." earlier in this section.)
4. If the problem continues, replace the axis driver.

Before You Begin
WARNING! Electrocution Hazard: When servicing the machine from inside the electrical cabinet, always use caution. Points in the
electrical cabinet have high voltages that can electrocute or shock you. Even after you've powered off the machine, electronic
devices in the electrical cabinet may retain dangerous electrical voltages. Only qualified electrical machinery technicians should
perform maintenance or troubleshooting procedures inside the electrical cabinet while power is still on.
Some procedures in this section require servicing the machine from inside the electrical cabinet. Before you begin, you must identify a
qualified electrical machinery technician to perform the procedures.
Cause: There's a loose wire connection or failed connector.
Probability How-To Steps Need More?
High / Low
Power off the machine (see "Power Off the Machine" (page35)). Then,
tighten all screw connections.
