Unlit LED
For NEMA 23/34 Models:
Check DC voltage at the power connector into the ClearPath motor using a voltmeter.
For NEMA 56/143 & IEC D100 Models:
Check AC voltage at the power input of the ClearPath motor.
Red LED
Return the motor to Teknic. To complete an RMA (return merchandise authorization) request, visit the RMA section of your account.
Blinking Yellow LED
Do not return the ClearPath motor. This is an application error that may disallow motion, not a motor failure. Note: depending on the exact error type, there will be anywhere from 2 to 7 blinks between pauses.
Troubleshooting steps:
Solid Yellow LED
Do not return the ClearPath motor. The LED is indicating that the motor is powered but not receiving an enable command (the Enable signal tells ClearPath to bring power to the motor phases to prepare for a command to move; a disabled motor cannot follow a command).
Troubleshooting steps:
Yellow/Green Alternating LED
Do not return the ClearPath motor. It is working properly, but there is a software conflict. One of the two solutions below should solve the problem:
Blinking Green LED
Do not return the ClearPath motor. This is an application issue or warning that may disallow motion, not a motor failure. Note: Depending on the exact error type, there may be 2, 3, or 4 blinks between pauses.
Troubleshooting steps:
Flickering Green LED
Do not return the ClearPath motor. The LED is indicating that the motor is enabled and ready to accept commands.

Blinking Yellow LED
Do not return ClearPath motor. The motor has an "Exception" which is stopping it from running.
Troubleshooting steps:
Solid Green LED
Do not return ClearPath motor. The LED indicates that ClearPath is disabled (windings de-energized)
Solution: Your application code must call the Enable command to energize the motor. Please see the sFoundation "sdk Example-Motion" for details.
Flickering Green LED
Do not return ClearPath motor. The LED is reporting that the motor is enabled and ready to accept commands from your software application code.
Step through your code to make sure the commands are being sent to ClearPath as expected.

Verify that your USB cable is 1) fully rated for USB 2.0 high-speed data communication, 2) is properly shielded, and 3) is 10' or less in length. Some USB cables (particularly those designed specifically as "charging only" cables) may not have the required data conductors. In addition, low quality cables often have poor grounding and/or shielding provisions.
